I do not know if next year challenges are set yet, but here are my suggestions for projects to run:

1. Seventeen or Bust: This is perhaps the most important and biggest project for Primegrid, so we really need to finish that DC and find an n for the remaining k's!

2. GFN17 low: Having two subprojects for GFN17 is messy, and the completitionist in me wants to see GFN17 finished. A nice challenge would help it along.

3. PPS: Similar to above, we really want PPS to reach PPS Mega :)

4. The Riesel Problem: We also want to further other conjecture projects than SoB, and the ones that weren't a challenge this year deserve to be a challenge project next year. TRP also has some low k's to solve, which are quite efficient computation-wise.

5. Prime Sierpinski Problem: This project sees quite little love, probably because people want to solve SoB first. Nevertheless, running a challenge might push this enough to solve a few k's

6. Generalized Cullen/Woodall: We'll be finishing the sieve for GCW during next year, so a challenge would be in place to find out those primes.

7. GFN22: This year we are running GFN21 (which we'll hopefully find!), so next year its logical to step up one step. Also furthering GFN22 would possibly take it to World Record level again.

8. Manual Sieve Challenge: There is still a lot of manual sieving to be done for GFN-projects. I dont know how feasible is a challenge with manual sieve hassles, but it would be a nice to have this at the start of the year to prepare for TdP and possible GFN challenges.

Another possibility is to have a challenge of the new sieve projects we've heard plans about (321 and CW sieves).

9. 321: Even though we had a 321 challenge this year, I think it would be a good project for a challenge because it is the most efficient LLR test.


What do you think? Any other suggestions or plans already in place?

A manual sieve challenge isn't going to happen. To explain briefly, I have no idea how well the server code would hold up under that kind of load. All the vetting of uploads is manual on my side. And can you imagine how many people would want to participate but have no idea what they're doing? I can, I deal with it all the time. Plus it's GPU-only with no possibility of running that sieving on a CPU (nor would you want to).

Yeah, this is what I thought. A shame though. It's lucky we have people like tng* and GDB doing so much manual sieving with their setups :)

A bit early to plan for next year maybe. I will.personally fit in with anything I think. I understand the manual sieving situation of course which will just be a smorgasbord of noobgasms.

I do not know if next year challenges are set yet, but here are my suggestions for projects to run:
...
What do you think? Any other suggestions or plans already in place?

In response to your comments.
SoB: Yep, it'll likely be a Challenge every year until the DC is complete.

GFN17 low: It's a long way to go. Challenge isn't going to change that.

PPS: 10+ years till it reaches PPS Mega.

TRP, PSP, GCW, 321: Sure

GFN22: Let's just see how the December GFN21 challenge goes. We're all keen for large prime but GFN22 challenge needs high end GPU to participate. Maybe a combo challenge makes more sense.

Manual Sieve Challenge: Not viable due to Admin overhead.

Other projects:
SGS not likely as it's sub-TK5
PPS Sieve and AP27 are also lots of fun.

No plans are in place at this stage.

I am interested to hear about ideas for Challenge format, what might be interesting.
We'll probably firm things up in a month or two.

This is Roger's area, so I'll only comment on a few that affect me. That means this is mostly "It can't happen because XYZ", but don't interpret that as me having a negative impression of the overall list. I like that people are getting involved.


1. Seventeen or Bust: This is perhaps the most important and biggest project for Primegrid, so we really need to finish that DC and find an n for the remaining k's!


This is high on our priority list as well so that we can complete the DC. Because of the length of the tasks, not many people run SoB, so the impact of a challenge is tremendous when compared to the normal crunching.

Note, however, that while completing the DC is a completely reasonable goal, completing the problem itself is a much longer task that might take years. Or decades. Or centuries.

2. GFN17 low: Having two subprojects for GFN17 is messy, and the completitionist in me wants to see GFN17 finished. A nice challenge would help it along.

3. PPS: Similar to above, we really want PPS to reach PPS Mega :)


While we may well have challenges for these projects, it won't be because we're trying to "finish" them. Those goals are incredibly far off, and a challenge isn't going to make a noticeable dent in those equations. Unlike SoB, these two projects have short tasks and are already pretty popular, so they're already being crunched a lot.

7. GFN22: This year we are running GFN21 (which we'll hopefully find!), so next year its logical to step up one step. Also furthering GFN22 would possibly take it to World Record level again.


We like the challenges to be open to all, and this is a GPU-only project. While we could in theory turn on the CPU apps just for a challenge, the fact remains that even on fast CPUs these are huge jobs and most computers, even with multi-threading, would struggle to complete even a single task.

8. Manual Sieve Challenge: There is still a lot of manual sieving to be done for GFN-projects. I dont know how feasible is a challenge with manual sieve hassles, but it would be a nice to have this at the start of the year to prepare for TdP and possible GFN challenges.


The technical and logistical problems with this are huge. Add to that the fact that both Jim and I are dead set against this, so it's never going to happen. Don't waste your time thinking about reasons why it should be done, or how it could be done. It's a non-starter.


I don't think it's ever too early to start talking about next year's challenges, so keep the ideas coming!

GFN17 low: It's a long way to go. Challenge isn't going to change that.

PPS: 10+ years till it reaches PPS Mega.


For GFN17low, I calculate that there is about 4 million candidates left = 8 million tasks (with DC). Average tasks per day for last year is 2,840. This means that with that rate, it will take 2,817 days = 7.7 years to reach GFN17mega.

But. During last november, the rate reached 110k (apparently there was a GFN15-17 challenge?). With this rate, it would take only 73 days to reach GFN17mega. If we have a GFN17low-only challenge, we could maybe reach 200k to 300k tasks per day. If we had, say, a 7 day challenge, we would actually test something like 20% of the remaining candidates during it.

For PPS, I agree that it has a longer time left. I calculated that there would be around 20 million candidates = 40 million tasks left. With a rate of 10k tasks per day, we have about 11 years left. The challenge we just had, reached 161k tasks per day = 0.4% of remaining tasks per day.

Disclaimer: These are just approximations! But I do think that GFN17low challenge could really have an impact :)

8. Manual Sieve Challenge: There is still a lot of manual sieving to be done for GFN-projects. I dont know how feasible is a challenge with manual sieve hassles, but it would be a nice to have this at the start of the year to prepare for TdP and possible GFN challenges.

Another possibility is to have a challenge of the new sieve projects we've heard plans about (321 and CW sieves).

9. 321: Even though we had a 321 challenge this year, I think it would be a good project for a challenge because it is the most efficient LLR test.


I'll break this post into two sections: responses and alternatives.

Responses:

SoB: An absolute must each year until the DC is done.

GFN17-low: The "completionist" in me wants to see that done with. I do enjoy running projects with finite end times.

PPS: See GFN17-low reasoning

TRP: We had SR5 this year and this is the other "small" conjecture so I like the idea of giving it a go. We had a challenge in 2017 to assist with that double check. But now we can push it forward.

PSP: The last PSP challenge, I think, was to assist that that double check. It's time for PSP to get a push forward. I would say that ESP gets less love than PSP, but we did an ESP challenge this year so I like the idea of swapping out with PSP next year.

GCW-LLR: No feelings on this one.

GFN-22: I'm not a huge fan of GFN-22 in a challenge. The tasks are way too large for not only CPU's, but even many compatible GPU's would struggle to do one unit within 10-15 days. I'd rather do one of the lesser appreciated GFN's like 18 or 19 if we do a second GFN challenge.

PSA: I'll defer to the other reasoning given for this one. Personally I've just avoided manual sieving and prpnet and stuck to BOINC.

321: No feelings on this one.

Alternatives:

PPS-SV: I know we don't really need a challenge in PPS-SV, but it is a great credit generator and is almost a break for a lot of hardware compared to GFN or AP.

SGS: A small CPU task challenge is always welcome. I enjoy seeing what people will throw at it. It's not T5K anymore, and PPSE would be better in that regard, but PPSE is likely going to get a lot of attention during TdP as it is the easiest CPU-only way to get a qualifying TdP prime. So SGS would be the logical alternative.

GCW-SV: If it's getting close to closing up shop then it might be nice to give it a "going away" challenge.

After that it would depend on whether any PRPNet projects are planned to be ported to BOINC or if any old sieves are planned on being resurrected. If there's any "new" projects then those should automatically get a "welcome to BOINC" challenge.

SOB, PSP, 321, TRP, GCW - of course!

And PPSE - I have already mentioned in discussion about Lennart honary challenge.

1. Seventeen or Bust: This is perhaps the most important and biggest project for Primegrid, so we really need to finish that DC and find an n for the remaining k's!


This is high on our priority list as well so that we can complete the DC. Because of the length of the tasks, not many people run SoB, so the impact of a challenge is tremendous when compared to the normal crunching.

Note, however, that while completing the DC is a completely reasonable goal, completing the problem itself is a much longer task that might take years. Or decades. Or centuries.



Sounds like maybe we should do a SOB challenge 2 (or 3) times a year...

Well, as I suggested in this thread: https://www.primegrid.com/forum_thread.php?id=8163

I still do feel strongly that we should honour Lennart by running a 65 days challenge on ESP. ESP were started by Lennart and are nescessary to prove that PSP is in fact the second Sierpinski conjecture for Sierpinski base 2.

In fact most of our projects, even PPS and all our conjectures would either not have been here at all or at least not have had advanced so much that they in fact have, were it not for Lennart.

So I therefor hope that we can run an honary challenge in 2019 for the best Swedish guy and the single most important person Primegrid has ever had enrolled in Primegrids list of volunteers/users. So could we please consider to run ESP as a single or split challenge to not only celebrate Lennarts 65 years birthday but also to acknowledge what he has done for Primegrid and all of us loving Primegrid?

If 65 days is too much for some users, then maybe we should do a split of the challenge, where some users crunch the entire 65 days on ESP while others split after the short challenge after ~15,7 days as some suggested.

If ESP is not interesting for the most users, could we then run the honary challenge (wich I hope we will run) on TRP then (with same length)?

Why a conjecture and why not something else, simply because Lennart, just like me were fond of the conjectures and worked for many years on the conjectures and helped CRUS advance in a very productive way. Unfortunantly Lennart vanished from one moment to another and noone knows for sure wether he is dead or alive, but no matter what, 65 years of age is quite a milestone - in most countries it means that your "working life" is over. None the less, what Lennart did will not in a near future (if ever) be matched so we could at least do something very Primegrid like and do something noone has done before and hold an extremely long challenge in honour of Lennart and his contributions :)

Just my 2cents of hope :)

Take care everyone.
