With the end of 2014 coming closer, I've been having a look at the challenge schedule for 2015.

Here's the schedule as it is currently. Dates are in MM-DD-YYYY format.

Date start Date end Duration Project Challenge 1-3-2015 1-18-2015 15 days GFN Long Year of the Sheep - Ram edition 1-3-2015 1-18-2015 GFN Short Year of the Sheep - Lamb edition 3-15-2015 3-20-2015 5 days SR5 Solar Eclipse 4-15-2015 4-17-2015 2 days SGS Lunar Eclipse 5-1-2015 5-9-2015 8 days WOO LLR World Expo 6-1-2015 6-4-2015 3 days ESP Sieve Summer of Sieving 8-10-2015 8-12-2015 2 days TRP Sieve Perseid shower 9-10-2015 9-15-2015 5 days ESP LLR Reign Record 10-4-2015 10-7-2015 3 days TRP LLR World animal day 11-12-2015 11-17-2015 5 days 321 LLR Leonids 12-19-2015 12-22-2015 3 days PPS Sieve Winter Solstice


There are several things to take note of in this schedule. In no particular order they are:

Last year I promissed to take a SoB challenge under serious consideration, as at that time it wasn't practical with a significant change in the size of workunits. I have done so and looking at the average time needed to complete one test (~14 days) I decided it would be for the best to not run a SoB challenge. The challenge would have to last all month and with the Tour de Primes following all month in February, that would be just too much. Not too mention the clean up, with timeouts taking two months a piece.

Returning participants might miss a PPS LLR (any variant) on the challenge schedule, as this has always been there. I have decided not to put it in, as SGS is getting pushed slowly to the end of the top 5000 primes and having a PPS LLR challenge would significantly speed up this process. This is at the moment not desirable form a PrimeGrid-wide point of view.

Finally there is the "Reign Record" challenge in september. The theme (and possiby dates) is dependent on Queen Elizabeth of the UK still being alive and ruling by then, as at that point she will be the longest reigning monarch of the UK.

With regards to the challenge leaderboard scoring I do not expect to implement any changes. Looking at the this years participant numbers, PSP and PPS had over 1000 participants, while the rest* had between 600 and 800. Therefore, 300 scoring positions seems still adequate to me.
Team numbers are also still between 100 and 300*, with peaks for PPS and PSP.
* With the obvious exception of GFN Long challenge, but that's an exceptional case.

Message 80424 - Posted: 20 Oct 2014 | 11:42:33 UTC - in response to Message 80419.

Please note that my comments in this post in no way reflect my minor administrative role here at PG--these are my personal views. As such, I have two suggestions regarding the 2015 challenge:

1) We still are not running a Cullen challenge? I have suggested this multiple times, but to my memory I do not recall ever running one. We have run multiple Woodall challenges, and now that project is significantly farther along than Cullen. I would suggest that we replace the Woodall challenge in May with a Cullen one instead.


2) The scoring of the GFN long challenge should be reduced. The bonus for this challenge in 2014 is much too high and has created a situation where those who did not run that challenge suffer on the overall ranking deficit more than others who have not participated in multiple other challenges. For example, only 4 individuals that did not participate in the GFN long challenge this year are in the top 50 overall participants (and all 4 of these have scored in all the other challenges). On the other hand, 6 individuals that did the GFN long challenge, but who have skipped other challenges (often multiple other challenges) are in the top 50. Additionally, another three users who scored in the GFN long challenge, but who failed to score in one or more of the other challenges are also in the top 50.

The GFN WR work is the most exclusive of all our projects (i.e., it excludes all/most CPUs and includes only higher-end GPUs and some mid-tier GPUs), which means that it excludes more users than any other work. Compounding that with an inordinately high bonus challenge credit seems ill-advised. For me personally, it has made this year's challenge series not fun.

Thanks for the feedback Scott.

We have actually run a Cullen challenge this year in May, so that's why thought it'd be nice to have a Woodall again this year.

I'll crunch the numbers a bit on the overall standings and how GFN WR influences the standings somewhen soonish. After I've done that I'll get back to you with an actual useful reply and to that part of your post.

I'm surprised to see no challenge celebrating PrimeGrid's 10th Birthday on June 12. As Woodall Prime Search is the oldest subproject that is still running, I suggest rescheduling the WOO LLR challenge to start or end on June 12, renaming it "PrimeGrid's 10th Birthday", and maybe extending it to 10 days.

The ESP Sieve challenge could then fill the World Expo slot from May 1 to May 4.

Another point: The Lunar Eclipse is on April 4, so date and theme don't fit together for that challenge.

Scott,

TL;DR: I don't mind lowering the point advantage, but it shouldn't be eliminated.

My take on the GFN-WR bonus is a little different. GFN is a project where you have both CPU and GPU participants, but the GPU program is very efficient and runs MUCH faster. Bonus or no bonus, the people with a bunch of big GPUs are going to dominate the leaderboards Even a crazy fast optimized CPU is still going to be 5 or 6 times slower than even a mid-range GPU. For someone such as yourself with a massive amount of computers at their disposal, but with (presumably) comparatively fewer big GPUs, I could see how that could skew the results against you and make it "less fun" as you say.

The bonus for the WR tasks doesn't change that. What it does change whether those GPUs are running the long or short tasks in the challenge. Since there's always an inherent advantage to running short tasks, and we want people running the long tasks, we either need to provide some incentive during the challenge for people to run n=22 rather than n=20, or we need to only run the n=22 challenge. In theory, we could just run an n=20 challenge, but it's n=22 that we want to promote.

That being said, while I think we need an n=22 incentive, I suspect even a small incentive would be effective. Perhaps lowering the challenge point bonus is warranted.

But even eliminating the bonus completely for the n=22 challenge won't change what you observed. Even with equal scoring, there's only 2 15-day challenges this year and one of them is GPU-only. People who don't participate in either challenge are going to be at a big disadvantage. Those two GFN challenges account for 30 challenge days in 2015, while the rest of the year has 36 challenge days. Each of the GFN challenges is therefore almost 25% of the total challenge for 2015. That's a huge chunk of points when you're looking at the overall standings.

Also, I'm a bit concerned that if we lower the bonus too much, all the GPUs will move to n=20. Not only is that not what we want for the project, but it would mean that the GPUs would dominate the n=20 challenge and people with only CPUs are going to be negatively affected.

(FYI Charley makes the decisions regarding the challenge. I'm providing the input on PrimeGrid's needs. The only time I would overrule him is if technically we can't do what he wants.)

Sorry...I was looking at previous years and forgot about this year. That said, however, I still would argue that Cullen deserves another run. Here is the distribution of all previous challenges (2008-2014 including those scheduled not yet completed) by active sub-project:

11- PPS LLR
8 - 321 LLR
6 - PSP Sieve
5 - TRP Sieve
5 - SGS LLR
5 - PPS Sieve
4 - Woodall LLR
4 - TRP LLR
3 - PSP LLR
3 - GFN (Short) *includes one GFN before short/WR division, but these were shorter than current GFN short
2 - SR5 LLR
1 - GFN WR
1 - Cullen LLR

(Defunct/Suspended projects included 2 - AP26, 2 - CW Sieve, 1 - TPS LLR, 1 - 321 Sieve)

As is clear from this list, Cullen is still behind all of the other larger LLR projects (especially considering that it was available before projects like TRP LLR, etc.)

Scott,

TL;DR: I don't mind lowering the point advantage, but it shouldn't be eliminated...



To be clear, I do not think a bonus should be eliminated. I just think that the bonus level this year was far too large (e.g., the 1st place GFN WR individual would currently be 43rd if they had run nothing else all year) given the exclusivity of the equipment to do the work.

I suggest running challenges that generate more heat in the northern hemisphere winter. What is the number of active PG members North vs Sourth of the tropics?

PrimeGrid has always done that in as much as during the northern summer months we either run sieve (low power) challenges or no challenges at all.

I don't have hard numbers at my disposal (and I don't have time to look them up), but the only major concentration of computers in the southern hemisphere is in Australia. Other than that, the vast majority of computers are north of the equator.

I suppose my thought is that running / not running a wr gfn is a user choice. Your pointing out the standing and results makes me think real hard on running the wr side next year. However, I did make a choice to run only the small gfn this year so in my humble opinion it's all about user priority. Of course I'm taking this as a comment on the challenge only.

Just my 2 cents, Rick

Would it be possible to have SOB challenge concurrent with short Genefer or Cullen? Replacing world record Genefer by running a separate challenge? Would world record task throughout become less if short Genefer were included with SOB tasks?

Maybe a 4 week challenge for SOB and for two of those weeks- short Genefer. This would create a separate two week challenge for World record. Or a SOB/CUL challenge for three weeks? Having a SOB/CUL challenge keeps Short/world record challenge as planned.

Is the server capable of sending a limit of SOB tasks to hosts? Two task for Quad core/ one task for dual core- if this concept is applied to CPU Genefer shorts being sent at the same time? Maybe create a BOINC notice along with message board notice explaining requirements to help minimize SOB clean up. (If server sends more tasks than physical cores [not counting HT]- please abort them.)

With a dual core Ivy- the CPU runtime to complete one instance of SOB- with other core free- 3-5 CPU AVX Genefers or 5-7 Cullen tasks can be completed. With a FMA Haswell quad core and quad AVX Ivy Bridge- CPU Genefer/SOB/CUL throughout is higher.

What if, instead of having simultaneous GFN-short and GFN-WR challenges, we ran a single challenge that accepted results from both projects?

On the plus side, there's a built-in incentive to run the long tasks because of the credit bonus (which is reflected in challenge scores).

On the minus side, people without GPUs can compete -- but almost certainly will not do very well going up against GPUs. It's the "don't bring a knife to a gunfight" scenario.

I'd have to re-write several scripts to make that happen, but it's probably doable.

Along a similar vein, addressing SoB, we could run a "Sierpinski Problem" challenge, where SoB, PSP, and ESP could all be used. Running the longer tasks, which have a bigger credit bonus, would yield more challenge points, so there would be an incentive to crunch SoB, while people with slower computers would still be able to participate.

It doesn't even have to be a 15 day challenge. People with really fast computers can crunch SoB in 4 days. Even my 32 bit Sempron can crunch ESP in 4 days.

Although I'll have to rewrite some of the code, assuming there's no unexpected roadblocks this has the advantage of not messing up BOINCstats.

Although I'll have to rewrite some of the code, assuming there's no unexpected roadblocks this has the advantage of not messing up BOINCstats.




I like this idea a lot! There are many users that run a widely mixed bag of CPUs and GPUs, and doing the above would allow for maximum participation in a number of ways.

Gets my vote,. I'll fit in anywhere tbh. Seems a shame to not at least attempt a SoB-ish challenge.

Definitely need to do something for 12 Jun. Maybe move the WOO + ESP/PSP sieve around a bit (WOO being just 1 exception to the rule of not doing LLR during hotter months).

Since there is code work to do, how about trying to schedule for 2016, since you want to make sure it works before giving it to the public.

I liked how 2014 has gone and how 2015 is shaping up. Some great ideas out there. I agree Woodall seems to have been missing from the challenge a lot and now seeing the numbers would like to see the Cullen one changed to Woodall for another year. Still up to you guys, but there is a lot of chit chat toward that.

The 10 year idea has some merits, also. Switching things around to fit that anniversary would be nice to see. I mean, 10 years of BOINC crunching of Primes, where things were then and where they are now. Could post all kinds of statistics about the numbers back then compared to now, including but not limited to, amount of users, computers, what the top of some of the project numbers were/are, etc.

Just some rambling from someone who likes this project a lot.

Random thoughts:

Flip the SR5 and SGS challenges, and make the SGS challenge a 1-day affair on March 20. I like the 1-day challenge idea as a test of my boinc management skills.

No SoB challenge == good

I liked the parallel GFN challenges in January 2014 and am happy to see them proposed for next year.

Lunar eclipse maximum is April 14 12:01 UTC.

Since we had "World Animal Day" challenge this year, how about "Octoberfest!" for 2015? (just a name change)

--Gary

p.s. The March 20 challenge could also be styled "Svalbard" or "North Pole" as the eclipse will actually be visible there. OK, in practical terms it probably won't be, as it will most likely be cloudy. And yes I've been to both places, so I'm biased :-)

Not necessary. There's no coding needed to make the challenge(s) run, per se. Most of the special "challenge code" is related to the scoring, which is just extracting information from the database. The rest is related to automating the challenge related changes to the home page.

If it doesn't work at first, there's plenty of time to fix it. Last year I substantially rewrote how the challenge code works, and didn't start until halfway through December. By comparison, this would likely be a much simpler change. With more than two months to go, we've got plenty of time to talk about what we want to do and then make it happen.

My 2 cents:
Make only one GFN challenge with short and WR. The latter credit bonus is a good.incentive to run them instead of short ones for crunchers with capable GPUs. This will also reduce the random luck factor. More than half of the participants of this year's GFN WR challenge did only 1 or 2 WUs, but theddifference in challenge points was huge between the 105th and the 170th, albeit both did just one WU.

At the same time, run a SoB challenge. Cpus are somewhat inefficient running GFN, so using cpus for SoB and GPUs for GFN at the same time would maximize the output.

Would introducing GFN @ N=21 ("GFN - medium") help at all? Or is that just a horrible idea?

When the N21s come online, will CPUs be able to crunch them, or will they require GPUs?

Alternatively, is it possible to have a CPU-only GFN challenge separate from a GPU-only GFN challenge?

The GFN software has limits, the value of B can only be so high before the software does not work.

n=21 won't start until we're done with n=20.


Only when the n=20 search reaches b=∞ can the n=21 search begin? /JeppeSN


That's only true if "we're done with n=20" means the same thing as "we've fully searched n=20". They don't mean the same thing, so no, we don't have to wait until b=∞.

For what it's worth, my current (and very tentative and subject to change) thoughts on this subject is that we'll search n=20 until about b=700k and then do something. We'll almost certainly start running n=21 as the short GFN with GPU apps. What's unclear is whether we'll also run n=21 CPU apps (they'll be rather long), and it's also unclear whether we'll continue to run n=20 as a CPU-x87 app on either BOINC or PRPNet. Running x87 transforms it's going to be really slow and it's not at all clear there will be much demand for such a project.

n=20 takes about 30 hours on my Haswell using the FMA transform. Using the x87 transform it's estimating 326 hours -- just a bit over 10 times slower.

Edit: n=21 is estimated at 137 hours using the FMA transform and 1405 hours (almost 2 months) using the x87 transform. For comparison, my GTX580 using the OCL app does n=20 in about 7.5 hours and n=21 in about 30 hours.

Thanks for all the great input people :)
I've been keeping up with the posts and PMs, but havent really had time to sit down and type a decent reply to the lot. So here goes (without quotes).

TLDR;
Some challenges will be moved
GFN WR bonus credit in a different form
Cullen will appear somewhere
First challenge might become shorter


GFN WR Challenge points
If I recall correctly the bonus percentage given took a bit of discussion to get to the rate it was set to. Looking at the current standings though these are things which stand out to me:
* Overall top 50 only has 4 people that didn't run GFN WR at all and another 15 that weren't in top 50 GFN WR
* 46 out of top 50 participated in both GFN WR and Short
* 20 people in top 50 overall were in top 50 for both GFN WR and Short

Decreasing the bonus on WR to 25% (i.e. halving it) not at whole lot happens imo. If I take the same stats as above we get:
* 6 none GFN WR runners, 15 none top 50 WR. --> +2 none runners
* 44 participated in both
* 19 people were in both top 50s

Only 3 people dropped out of the top 50 by halving it. I'll go and fiddle a bit more with numbers later on, but I'm not expecting a much larger shift.

Multiproject challenges
The idea has been raised to do a challenge across multiple subprojects on one leaderboard. For example as Mike mentioned an Sierpinski Challenge on SoB, PSP and ESP. You choose which one to run based on what your system can handle and credit is accumulated across the projects. I think this is a brilliant idea and a great way to solve the previous point.

If we simply use the current PG credit wizardry there's already a "credit bonus" in there for the longer tasks. This way you will get a better position on the leader board for that challenge and thus a better score overall. You will however not get a X% credit bonus on the yearly leader board. This way there is still a benefit to running longer tasks, but the benefit is reduced compared to this year.

Considerations
*Do we allow people to submit results from multiple subprojects?
From a user perspective one could argue that allowing it is NOT a good element of challenge, as disallowing this requires strategic planning and knowing what your box can handle.
On the other, one could also argue from a user perspective that it is a very good element of challenge as allowing it requires strategic planning, knowing what your box can handle and more hands-on management. (No I purposefully copy/pasted part of that sentence, it's not a mistake ;))

From a project point of view I'd argue that allowing is the best option, as one of the goals of challenges is driving computing power towards certain subprojects. Therefore allowing, even encouraging, people to fill the challenge timeslot to the max is the best option.

Lunar Eclipse/Birthday party/Pentathlon overlap
I'd rather not move an LLR challenge into June as things will already be heating up then. What I'd rather do is the following:

Move the Lunar Eclipse challenge to april 4th, the World Expo challenge to end on May 1st rather than start at that point and move the summer of sieving challenge to end on June 12th and rename it to something more appropriate.

Cullen vs Woodall
I'll do some shaking all about and make Cullen appear.

Number of challenges/total length
I've got signals that this years 12 challenges/60 days was a bit much and I tend to agree. The schedule as it is posted above is now 10 challenges and 50 days. I might remove one challenge or more likely will shorten the first one. I need to think the exact details through a bit more, taking the multiproject challenge into consideration. I'll post a fully updated schedule in the next couple of days.

Although not impossible, it would make the challenge scoring scripts more complex, and likely make the database queries more complicated as well -- and they're already rather beastly. I'd rather not deal with having to figure out whether the user is running multiple subprojects in the challenge, so my very strong preference would be to allow it. That way I don't need to try and figure out whether a user/host is running more than one project.

I very much prefer allowing it, though for different reasons than Mike. Using a hypothetical example of a user with three machines (which is fairly common I think) and the notion of a Sierpinski combined challenge, one could easily see such a user running all three projects (e.g., an old Core2 laptop on ESP, a slightly newer i7-950 on PSP, and a shiny new Haswell i7 on SoB, etc.). This maximizes the user participation (and challenge results) as well as maximizing the benefit to PG overall, especially across what may be hundreds of similar users.

I agree with Scott, if we do a multiple subproject challenge count all work from users on any of the subprojects involved.
I am one of those users with a mix of hosts so would aim for the best subproject on each of them.

Multiproject challenges
The idea has been raised to do a challenge across multiple subprojects on one leaderboard. ...

Number of challenges/total length
I've got signals that this years 12 challenges/60 days was a bit much and I tend to agree.

As expressed via PM, those those subjects are somehow connected.
Some subprojects are getting longer and longer.
Putting them on Challange list make challenge longer.

If we don't implement multiproject challenges, we end up with longer and longer challenges or in need of skipping more and more subprojects from challenges (and possibly have them every other year) sooner or later.

Having multiproject would enable PG to run all/most subprojects every year and even allow running some that would have been otherwise excluded (SoB).

Making challenge schedule might be easier as well.

As I see it - short term pain, long term benefit both for participants and project.

Scott,

TL;DR: I don't mind lowering the point advantage, but it shouldn't be eliminated...



To be clear, I do not think a bonus should be eliminated. I just think that the bonus level this year was far too large (e.g., the 1st place GFN WR individual would currently be 43rd if they had run nothing else all year) given the exclusivity of the equipment to do the work.


To return to this part of the discussion:
I'm currently 250th overall. I contributed to every single challenge, except Stallion, since at that time I had no GPU that was strong enough. I tried, but I couldn't even get close to the deadline. I managed to contribute to the Pony challenge and everything since.

There are 12 users in front of me who only participated in the first, double challenge (both stallion and pony), and nothing else.
There are a further 23 users in front of me who only participated in only 1 of the first challenges, so either stallion or pony. Some of them did only 1 single WU. It's now november, and they're still in front of me.

I don't mind, but if a single (stallion) WU (agreed, a long one) can outscore all the WU's I have crunched since then, maybe the bonus for long challenges should be reviewed...

On the other hand, maybe it's not the bonus for the long challenge, but the fact that only 175 users participated in the stallion challenge. Even the last one got 1209 challenge points (I repeat: for a single WU). The last one in any other challenge (including pony) got exactly 0 challenge points. So the problem seems that not enough users participated in the stallion challenge, with exaggerated scores not for the leaders of the challenge, but for the users down the list, who did a minimum of work for a big return.

If I had done a single stallion WU, on top of everything else, I would be 65 places higher on the overall scoring list.

Which, all things considered, has very little importance.

Even the last one got 1209 challenge points (I repeat: for a single WU).


But it was one REALLY huge task! :)

I think there's almost universal agreement that the bonus needed to be reduced. We're definitely changing the structure of that challenge next year, and it's likely that there will be one combined GFN challenge with both size tasks and the challenge will be shorter. Since the challenges are combined and there won't be a "GFN-WR" challenge, we won't repeat that situation where a single task will be all it takes to score high on the leader board. Combining the challenges also permits having shorter challenges, which have fewer points, which reduces the overall weight that a single challenge has.

Bottom line: it will be better in 2015.

Please find the adapted schedule below. I'll highlight the main changes below it.

Date start Date end Duration Project Challenge 1-3-2015 1-11-2015 8 days SoB Year of the Sheep PSP Year of the Sheep ESP Year of the Sheep 3-15-2015 3-20-2015 5 days SR5 Solar Eclipse 4-23-2015 5-1-2015 8 days GFN Long World Expo GFN Short World Expo Cul World Expo 6-12-2015 6-15-2015 3 days ESP Sieve PrimeGrid Birtday Challenge 8-10-2015 8-12-2015 2 days TRP Sieve Perseid shower 9-10-2015 9-15-2015 5 days ESP LLR Reign Record 10-4-2015 10-7-2015 3 days TRP LLR World animal day 11-12-2015 11-17-2015 5 days SGS LLR Leonids 12-19-2015 12-22-2015 3 days PPS Sieve Winter Solstice


The main changes are the multi-project-challenges (MPC). This new form of challenge will address two issues. Firstly it will allow us to run challenges on subprojects which would otherwise have to run for a month. Secondly it will iron out the wrinkles which turned up in the scoring bonus of the GFN long. As scoring will be simply using the standard BOINC scoring mechanism, people who are able to complete a GFN Long or SoB will get a bonus on the leaderboard of that challenge and will thus be able to get a higher position and a better challenge score. They will however not be able to get a ridiculous amount more, by participating in multiple challenges at the same time and thus score on two leaderboards at the same time.

To match the MPC the first challenge of the year has been reduced from 15 to 8 days, which should also hopefully reduce the cleanup time.

The lunar eclipse challenge has been completely removed to keep the number of challenges down and have a breather between challenges.

The world expo challenge has been put on a bit earlier as to avoid conflict with the BOINC Pentathlon and is also changed to a MPC. You will notice these are the GFNs and Cullen. Although they are not mathematically linked, this is a nice combination to allow some battling to take place.

The June challenge has been moved over a couple of days and rebranded as the PG Birthday Challenge.

And in a break with tradition the Leonids challenge in November has changed from 321 to SGS, as SGS has had less attention than 321 and will more quickly disappear from the top 5000.

The introduction of the MCP means that the bonus credit as used this year in GFN Long challenge will no longer take place.

Thanks Charley, I like the idea of MCP.

Just one comment - putting CUL in with the GFN challenge seems a bit odd to me. The other MCP has PSP,SOB,ESP which are all linked by the fact that they are Sierpinski conjecture projects, and use LLR (with WUs of varying size). I think it might be better to replace the ESP challenge in September with CUL. 5 days is enough for CUL (the WUs are shorter than WOO), and anyway ESP is already included in the January MCP. Plus the CUL tasks should run a little cooler than ESP since the FFT length is larger, which is an important consideration for those who will still be in a warm(ish) climate during September.

Cheers

ESP-LLR is in there twice. How about replacing it in September with either 321 or Woodall?

To match the MPC the first challenge of the year has been reduced from 15 to 8 days, which should also hopefully reduce the cleanup time.


I wish that were so. Sadly, the major factor in the cleanup length is the deadline for the tasks, which, in this case, is a whopping 60 days. I expect the cleanup for this challenge to take most of 2015. It doesn't matter much how long the challenge itself takes.

Message 80768 - Posted: 12 Nov 2014 | 10:04:12 UTC - in response to Message 80766.

W/r/t the SoB cleanup, how about if after one single normal (60) length period starting on the 18th, re-issue the remaining challenge tasks only to hosts that completed one in the original challenge period or in a later period in the cleanup (mid-March) but took no longer to do it than the challenge itself lasted (15 days). I give one full-60 day window after challenge end to give the world a chance to do cleanup.

I have no idea how difficult this may be from a programming standpoint, but it would at least knock out the much slower hosts, and get the "disappeared" hosts out of the way to. I can see that hosts "trusted" with the shorter window early on may still disappear later, but they'd recycled more quickly to remaining hosts.

Any other machine that shows up after the first 60-day period could still of course run SoB, just not challenge cleanup.

If too difficult, or I've missed something obvious, then never mind. I believe I saw a long time ago that once a WU is created, it's deadline can't be changed, so it might have to be done by causing the server to issue triplicate, "premature" work, if possible.

Cheers, and thanks for the work on the schedule, Charley.

W/r/t the SoB cleanup, how about if after one single normal (60) length period starting on the 18th, re-issue the remaining challenge tasks only to hosts that completed one in the original challenge period or in a later period in the cleanup (mid-March) but took no longer to do it than the challenge itself lasted (15 days). I give one full-60 day window after challenge end to give the world a chance to do cleanup.


Ignoring the question about whether or not it's technically possible or not, this is something I'm opposed to on any of the primality test projects (LLR and Genefer).

Intentionally sending resends to "reliable hosts" may help speed up the cleanup, but for people hunting for prime numbers, it penalizes them for being reliable. Have a reliable computer we can count on? Fine, we'll send you tasks where there's already a result in so you're guaranteed to be the double checker with no chance of being the prime finder. This is definitely not what we want to do.

A long cleanup isn't a problem looking for solution. It's merely a characteristic of the challenge.

Would be better to have the GFN projects earlier in the year as originally proposed or move GFN tasks to March. These cards tend to run hot and the cooler weather is a welcome relief to crunch these tasks. The GFN N=22 tasks are particularly difficult to process as they run for more than 2.5 days and need all the help they can get.

Opinions will definitely differ depending on one's geographic location, but I agree with this. By May it's likely to be warm enough where I live that running a GPUs (and CPUs -- with this MPC you can't even idle CPUs to reduce thermal load without reducing challenge output) all out will result in hot spots in the house, which can result in errors on GFN long.

Just one comment - putting CUL in with the GFN challenge seems a bit odd to me.

Cheers

Just wondering about the reply to this. I'm somewhat confused as to how a "single" challenge will work when you have 2 gpu projects and a cpu project (unless of course I missed some exciting news that the Cullen project was now gpu viable) combined. I might have missed a major point somewhere that explains how this is suppose to mesh together.

Cheers Rick

Message 80781 - Posted: 12 Nov 2014 | 23:52:41 UTC - in response to Message 80780.

In my head, which is quite a weird and interesting place at times, this made sense because GFN Short is GPU/CPU, but CPU is so long (average of 130 hours/5.4 days) that a fair amount of people won't be able to get a lot of work done. To allow them a greater chance, I thought I'd add a long-but-quite-as-long CPU project. Cullen fit the bill with just under 81 hours (~3.4 days) on average with the added bonus of public interest.

As pointed out by several people who are sharper than I was when making the previous post ESP is in there twice, which will be changed. I could change the second one to either CUL en pull CUL out of the second MCP, or switch it to 321.

The Sierpinski-MPC is staying where it is, due to the mega clean up expected on SoB.

I didn't quite take into consideration the climate of all of our participants when putting the GFN-MPC at the end of April, as I have a strong bias towards local weather conditions. (That is, cold, wet and dreary except for some random days between April and October.)

As I said, opinions will differ. By 9 May, the average temperature here is 85 Fahrenheit ( 29 Celsius) with a record for that date of 99 Fahrenheit (37 Celsius). I'll deal with it (managed 6th in the August challenge this year, much worse than May).

Date start Date end Duration Project Challenge 1-3-2015 1-11-2015 8 days SoB Year of the Sheep PSP Year of the Sheep ESP Year of the Sheep 3-15-2015 3-20-2015 5 days SR5 Solar Eclipse 4-23-2015 5-1-2015 8 days GFN Long World Expo GFN Short World Expo 6-12-2015 6-15-2015 3 days ESP Sieve PrimeGrid Birtday Challenge 8-10-2015 8-12-2015 2 days TRP Sieve Perseid shower 9-10-2015 9-15-2015 5 days CUL LLR Reign Record 10-4-2015 10-7-2015 3 days TRP LLR World animal day 11-12-2015 11-17-2015 5 days SGS LLR Leonids 12-19-2015 12-22-2015 3 days PPS Sieve Winter Solstice

The solstice challenge(s) have traditionally started/ended at a time of day to coincide with the actual astronomical event. Maybe the eclipse ones too. But that would be up to you guys, of course.

Question about the scoring: for a multi-project challenge, will there be 3 (or 2) separate leaderboards and scoring, or a single combined leaderboard? This year in January we had essentially two separate challenges running in parallel. Either way is OK with me; just wanted to clarify.

As Mike said: 1 single combined leaderboard. This will allow is to still give a bonus to long(er) tasks, without having the huge impact it had this year.

What if, instead of having simultaneous GFN-short and GFN-WR challenges, we ran a single challenge that accepted results from both projects?

...

I'd have to re-write several scripts to make that happen, but it's probably doable.


All server changes related to running MPCs (Multi-Project Challenges) are now done.

Currently the "PrimeGrid Birthday Challenge" is set to run for three (3) days/72 hours from 12 June - 15 June. This Multi-Project Challenge currently has SOB/PSP/ESP-Sieve tasks that will be participating in this challenge. The most recent challenge "Year of the Sheep" had SOB tasks as part of that challenge. From the earlier posting regarding the fastest CPU to process SOB tasks the following information was disclosed:

(Number of results / minimum CPU time in hours, rounded down)
i7-5960X: 20 / 94
i7-5930K: 0 / -
i7-5820K: 3 / 102
i7-4790K: 27 / 84
i7-4790: 8 / 131
i7-4770K: 118 / 83
i7-4771: 7 / 125
i7-4770: 95 / 86

i5-4690K: 0 /-
i5-4690: 2 / 91
i5-4670K: 25 / 84
i5-4670: 27 / 97

http://www.primegrid.com/forum_thread.php?id=6044&nowrap=true#82224

Since the fastest CPU from the most recently run challege takes longer than 3 days/72 hours, would it be best to either extend the challenge or substitute another sub-project?

I know the 2015 challenge series is set. But it seems we are in a new era of combined sub project challenges. So why not make the Cullen challenge a combined Cullen/Woodall challenge. They are related and about the same size. This way people have a choice and a slight amount of extra strategy may be used, seeing the projects are about 5-10% different in size/time.

Bumping this thread. Anyone else have an opinion on combining Cullen & Woodall for the Reign Record Challenge in September?

I guess Charley is the one to make the final decision, so, Charley where are you.

Who says old dogs can't learn new tricks?

Looking at the run times of some really slow computers, we've decided to swap the durations of the World Animal Day challenge and the Leonids Shower challenge.

The TRP-LLR World Animal Day challenge is now 5 days. The SGS-LLR Leonids Shower challenge is now 3 days, and will start two days later on November 14th.
