Question - will gfn 17 low count this year for the tour? Looking at the main page I think so but wanted to make sure. |

Looks like it. They're more than big enough to qualify. |

Yep I think everything counts apart from 15 which is not T5k. Depends what jersey(es) you go for though. The lower the GFN the less efficient they are on faster cards. |

I'll be running medium-to-large conjecture projects in the forlorn hope to blow everyone's socks off with a huge find. Except for the "mountain stage" day.

My thoughts on the various jerseys:
Prime count - statistics take over from luck for the big farmers, so personally it isn't one that is realistic.
Mountain stage - unlike the above, the shorter duration does bring luck back into the game, so worth throwing what you have at it.
Largest prime - how lucky do you feel? Worth a try, and keep an eye on what's currently largest so you can one-up them.
Prime score - Tough one this. Do you go for many smaller, or hope for the big one? A big find will be hard to beat.
Last year I ended up getting a few different types of prime, which isn't a challenge. I didn't even top that. |

Everything except GFN15 counts for the tour.

Right. Those primes are comparatively tiny. If you happen to find a really long AP, you'll get recognition elsewhere :-)

There is almost a necessary choice between going for count and going for largest. I don't have the CPU horsepower for the former, and some of my GPUs can't run GFN16, so I plan on trying for the latter.
Last year's largest was a GFN 18, I believe, which is where I'll park my GPUs, except for the mountain, where I'll move my non-mac/AMD ones to 16 and the mac/AMD ones to 17-low. My avx cpus I'll park on PPS-Mega, and my non-avx cpus I'll park on SGS (or maybe GFN16). That should minimize administrative overhead as well. |

I know the gfn 16 seems to be folks choice for prime count (gpu). I think I ran several 16's and 17 lows just to see how long each took vs credits and the 17 low won. So I plan on moving all my gpus to the 17 low and what cpus I can to pps-mega.
It's a crap shoot anyway on getting the largest or most points for primes (except for Scott) :)
Heck who knows, I might follow zimmer over to 18's for a bit during the month.
Oh and @AA I also issue a challenge to you big guy. You soundly beat me in the last challenge so lets see who gets either the most primes or the most prime points - you decide which or both :)

Good or bad, I am not one to turn down a challenge! :-)
Thanks to Zimmer and yourself for the advice on which subprojects to run. LOL! (I guess no more GFN20 (CPU) during the challenge :-( )
Edit: Given the challenge posed by RR, I guess the flip to Jade (10M) for GCW Sieve will have to wait (I will be falling a couple of days short by the time TDP starts and will have to wait a full month to restart).
Edit 2: Interesting that I have been challenged by someone who did not have a SINGLE find last year during the challenge: http://www.primegrid.com/challenge/tdp_2016.php .... it should be like taking candy from a baby! |

Ah you will be able to get a good ways before Feb. The good news is you and I will at least move forward on GFN, PPS and SGS (if you run any).

I have almost 190 pending GFN20 tasks, which should last a while...
The chance of hitting on GFN20 is really really small though, so it probably isn't a good TDP project, in any event. |

Unless something weird happens like finding a 3 million+ digit prime in the first few days of TDP, I think my sights are set on a green jersey. I already have plenty of those yellow ones anyway. :)
With a crazy mix of GPU and CPU, I'll probably have most of my GPUs on GFN18 (maybe some slow ones on GFN16 or 17low). AVX or better CPUs I am still thinking about. Probably PPS Mega or SR5, but ESP might be a fun option. Slower CPUs are headed for SGS/PPSE/GFN16/PPS in some manner depending on where most others seem to be placing their action.

It is rare for me to start on a unit and which somehow is not pending credit from you! LOL.
I just uploaded two results and was surprised that one of the replacement tasks was a "virgin" (it has yet to go out but I am sure it will get to you shortly anyway).
The chance of hitting on GFN20 is really really small though, so it probably isn't a good TDP project, in any event.
I went through a similar route last year (ex. 321 and Cullen) so as to also get the Gold badges at the time. However, I am now in a position to "splurge" and will seek to optimize for TDP rather than key on badges, RAC etc. If nothing else, someone threw down the gauntlet! |

The only way for a mere mortal to outdo the big guns is to go for the long ball. I think we had something similar last year where one wild result basically put an end to the challenge. |

I'm guessing that if RR gets to choose, it will be some form of corn distillate. |

Haven't had a think about my strategy yet other than trying my luck going large. I'm thinking CPUs on SR5 if Scott doesn't own it*, otherwise TRP maybe. GPU wise I might not run much due to heat problems, but it'll potentially be one on GFN21, lesser GPUs maybe GFN18.
*As seen in the past, if a single user is doing a big enough proportion of units on a single subproject, it can reach the stage where others will get mostly double check work. Not a problem on small unit/popular tasks, but could be significant on less popular longer units. |

The other end of this problem for the user with lots of boxes is not getting any work because the server won't allow you to double-check yourself.

Something that crossed my mind is whether it would be practical for ALL tasks going out during a challenge to be first-time transmissions and for the clean-up to involve the double-checking of these tasks. |

I haven't decided what I'm going to do.
On the one hand, I might just stick with what I'm running right now: PSP (DC) and GFN20. Either of those would likely win the red jersey and possibly the green jersey as well. It's what I'm running anyway and does have the potential of bringing home a jersey. A small chance is better than zero chance, which is what I'd have running small tasks.
Or I could go small. No chance of the yellow jersey, of course, but a stroke of luck could win the mountain stage. But my real motivation would be that I haven't found any of the new (n=1290000) SGS primes, nor have I found a PPS/PPSE prime. So I might run those just to get on the TDP leader board and get one of those primes added to my personal list. (I've been DC for those, but never the prime finder.)
If I'm not doing a challenge, and not going for a badge, I tend to choose projects based on PrimeGrid's goals rather than my own. That's why I'm running PSP(DC) on the fast cores and GCW-Sieve on the slow cores.
Or maybe I'll just go for snake-eyes and run SoB on the CPUs and GFN22 on the GPUs. It's not like I haven't had that kind of luck in the past.

Absolutely not. That would mean waiting nearly a month for primes found early in the month, which would mean people would be waiting a long time for credit.
But the absolute deal breaker is that we can't hold a month's worth of SGS and PPSE tasks in the database, especially when activity in those two will be higher because of TDP. (This is why challenges on short tasks like those are always of short duration. 3 day challenges are pushing it; 1 day challenges are much better. 28 days??? Fuhgetaboutit!)
Sorry, but even if I wanted to this (I do not), this idea would be dead in the water.

Just got twelve or so of these new toys to replace almost all of my old aging e8400 boxes. Should provide a little more bump for the TDP. :)

Grad student research lab (with no budget, so these are hand-downs from the business school...as were the e8400s they replaced). Machines are on all the time anyway as lab boxes.

Ah makes sense - I figured you were doing double duty with them in some way. I don't miss those college days. At my age I have no patience for the way I acted back then. |

Last weekend before TDP starts... gonna go around all my boxes and turn off HT to simplify matters. Also going to bling a box up. Doesn't actually help performance but it'll just feel better running it :) |

I got two live (small) alberta spruces for Christmas trees as gifts, and each had a 3AA battery powered string of leds for lights about 3 feet long. I'm thinking these would be perfect for a prior recommendation for hooking into a HDD activity header... |

Took a LOT longer than I thought... about 8 hours? And I need to improve the wiring in a lot of places but happy enough to get it working. Quick photo with phone.
My main system in new nvidia fanboy edition case. The fans are green but the camera is doing some weird stuff with colours. The system was water cooled but I had some vibration problems as well as residue in the loop so it needs a deep sort out, not something to be done quickly hence reverting to air. I need to do more configuration to fan speeds but seems to be working ok for now. |

I will likely stick to SR5 for most of the challenge, switching to PPS or MEGA for Mountain Stage day. After doing a much needed dusting on my computer, temps with 4/4 cores on SR5 is ~66°C.
Need to redo my dual E5-2670 system, can't get the networking to work after trying to get it to work on wifi while I waited for my SFP module... If I recall correctly I already disabled HT in the BIOS.
Found my first MEGA in last year's TDP, let's see if I can beat it ;)
Good luck everyone!

Just in time for TdP I had a 7990 overheating. It looks like 2/3 fan bearings were going-spinning, but too slow (7990 reference cooling is marginal at best).
I was impressed at how the card throttled. Temperature would climb after boot until it hit 100C on GPU1, at which point GPU1 throttled from 1000mhz back to 500mhz, where it cooled back down to 67C and chugged (crawled) happily along.
A good cleaning and fresh coat of Gelid, and it is back to high 60s.

All my hopes are pointed to GFN 18 :) If you look at GFN 18 discoveries, it is in regular "distance" so one prime should appear in near future :) Hope I found that one :)

I was debating if GFN16 was interesting or not for Sandy Bridge. In short, no. My Xeon does those in just under 2 hours. SGS takes under 20 minutes. PPS would be next bigger but I'd expect still far below 2 hours.
I've kinda decided I'm going CPU only on this. It's still too hot to run GPUs. Then again, I have a cunning plan, but it will take some time to implement and wont be from the start. |

Gonna start the TDP with PPS mega on my "fast" cpu's, SGS on my slow cpu's and GFN17 on all my gpu's hoping to find a prime or two. No way I can compete with most primes so might as well shoot for a decent score.
@Gary - please please make sure your voodoo and other good luck activity is sent this way

Hey RR, you are worse than a woman: yes, no, maybe, no, I changed my mind, yes, no, no, yes, thinking about it, no, yes, yes, no, no, okay, just maybe yes, just maybe no, okay back in, I really mean yes this time, no, no!, yes, yes, yeap!, no, yes, no, yes, yesssss, no, oui, non, nyet, da, I am not so sure, no, yes ....
So, is it going to be by the number of primes or total score? |

I will wait roughly 24 hrs so that the AP Ruby will be locked up (with pending credit included) and at which point I will park my GTX 1060 and 1080 onto GFN 22 whereas my dinosaur GTX 660M will be doing GFN20.
As for my CPU's, I will park them on PPS Mega and SGS (both projects selected simultaneously in the preferences). GCW Sieve and AP will have to wait for a restart on March 1st. |

Say what? I never changed my mind! I just asked for my glove back to keep my hand warm. (Not my fault you mis-interpreted the meaning) However, should you beat me I'm sure I will wish I did.
As a golfer we do play for small change each time so I know better than to try and wiggle out of a "bet" :) Sadly I even lost yesterday.
Interesting that you will run Megas and SGs at the same time. Might have to see if that works and it sounds like you are going for the knocked out prime.
@Z - you sure do stir the pot |

Yeah the start is midnight (00:00) UTC 1 Feb... so that means something in the late afternoon or early evening the day before for those of us in the states... And it's reporting time that counts, so you can start a little early. "Bunkering" won't likely work as only the initial finder gets TdP credit, not the double-checker.
I've got a "rolling start" going already on TRP-LLR... burned off my sieving backlog this morning.
Best,

Thanks for the confirmation.

I was planning on that by starting now on GFN 22 but that means no AP Ruby. I will wait the extra 24 hrs I need for the AP Ruby and start six to seven hours early anyway for whatever its worth on the GPU side for TDP.
Good luck to you as well. |

I am looking to isolate work on the CPU side and, as a result, I will restrict my units to PPS Mega and SGS. This will allow the CPU and GPU to work independently with no conflicts between them for memory. |

Starting to move over my stuff into TDP mode (sadly, looks like the GCW sieve badge will have to sit about 3 million short of double bronze until March).
For those interested in the GFN18 current GPU run times, here are some I have quickly gather by card family (numbers are rounded and given in ranges when I have more than one card...units per day assumes 24/7 crunching):
Pascal
GTX 1060 1,500 seconds 57-58 units
Maxwell
GTX 960 2,300-2,775 seconds 31-38 units
GTX 950 2,740 seconds 31-32 units
Kepler
GTX 660Ti 2,560-2,670 seconds 32-34 units
GTX 660 OEM 3,015 seconds 29 units
GTX 645 6,380 seconds 13-14 units
AMD
RX 470 1,810 seconds 48 units
Not sure why the GTX 960s seem to perform so poorly compared to the GTX 950???

Any chance they are getting too hot or running into a power limit?
My 1060 is not behaving at the moment. |

No. Actually, the fastest one is probably running hotter than any of the others thanks to the 660TI installed next to it.

Slowly clearing out my very small cache of GCW Sieve with the Preferences and Computing Preferences already set.
i7 6700k ... PPS Mega and SGS for the CPU and GFN 22 for the GPU (GTX 1080)
i3 6300 .... same scenario as with the i7 6700k for both CPU and GPU (GTX 1060|
i3 6100 .... GFN 20 (CPU) since no GPU available for memory conflicts
i7 3630QM ... PPS Mega for CPU (SGS too stressful on the laptop) and GFN 20 for the GPU (GTX 660M)
My two Dell C2D (P9600, 2.67 GHz) are humming just fine with GCW Sieve and will remain parked there for the foreseeable future. |

Think I'm going to try what I call a prime escalator. I'll do SGS until I get a prime, then PPSE, then PPS, and so on. I think I managed to get 3 or 4 types last year but not necessarily this way. As a variation I will put fast systems on SR5 for hopes of a bigger one. |

6.5 hours to go. Made my last pre-TDP tweaks. Got my 1060 firing on all cylinders again. All is set.
Now, if only everything holds together for a month. |

SGS currently has Prime Rank 4489.
Finding anything larger than an SGS will knock it down a peg.
Lets see if it can hit 5K+
I am all switched over to TDP mode. |

Not a great start for me. Temperatures are rising so I'm not even running all CPUs at moment, never mind thinking about GPUs. Gone in part SGS/SR5 and will see what happens... |

If you're having temperature issues, you might want to stay away from SGS and possibly PPSE too. At least on my Haswell, it run a lot hotter on SGS than on longer tasks.

Not system temperature, house temperature. It has been relatively mild so temps are increasing. So I have to moderate my output according to weather. I might have to enact my Plan B but it will take some time. |

What would be really cool, and probably WAY too much work to implement (if even possible), would be a status page showing the frequency of primes found by subproject. Similar to the individual pages which shows percentage of tasks with a prime, except PG-wide. For the GFN projects, to be meaningful, it would need to be by subproject.
That would be quite useful for TDP task selection... |

Me too.. gfn 17 low full blast, pps mega (limited on some systems) and sgs 1 core. Already see a gfn 17 mega has been reported and a couple of others so there's hope!

If only we had team jerseys for TDP, maybe for highest total prime score...
I am firehosing GFN18s as fast as I can. I'd be curious what run times you are getting on 17-low.
What I don't understand is that I am running SGS on only older/slower non-AVX CPUs. Somehow I have amassed 999 pending units. Whoops, make that 1000.
One observation I made on an older dual-core i3, if I didn't reserve a CPU core for the GPU (GFN18), GPU utilization was maxing out (flapping) between 73-76%. If I did reserve a core it stays at a rock-steady 86%. I guess those lower Ns really do need more CPU attention.

I have I7-2700K running Prime95 of 4 cores ( 2 workers , every two cores) and in background 750Ti running GFN 18. Task manager show 96% utilization from Prime95 and 0% utilization on GFN 18. So it looks like sweet spot to me :)

I am less than 24 hrs away from completing the first GFN22 on my GTX 1080 and I will report the run time once it completes. I am looking at around 44.5 hrs from start to finish (with PPS Mega and SGS busy on all four CPU cores).
About 24 hrs later, my GTX 1060 will also be completing its GFN22 and I will report its run time as well (also with PPS Mega and SGS busy on all physical CPU cores).
I still cannot believe the punch these cards provide! |

My GFN18 completion times on that machine went from ~1560 seconds to 1264. 20% improvement not too bad, albeit at the expense of running that second PPS-Mega unit. |

Am soon on some PPS Mega up to a suitable point. In fact might take it to 4M. GPUs must stay on AP for the time being. |

Nope, I'm not going to build a statistics page that shows how common primes of different types are.
If you want that, go and tabulate the primes from last year's 2016 TDP. You'll want a larger data set for those statistics anyway. Don't bother with any primes larger than, say, PPS-MEGA or GFN-17-MEGA, since they're too rare to give good statistical information.

Now add the wingman also using punch cards and a decade per unit is not out of the question. :-) |

Run times for gfn17-low - note cards are slightly over clocked but most on old systems with memory limits
660ti - 816 - 847 seconds
770 - 647 - 718 seconds
970 (1) - 635 - 653 seconds (half size)
970 (2) - 563 - 617 seconds (full size card)
1070 - 372 - 422 seconds (did have 1 that took 649 seconds for some reason)
overall not as fast as I've seen others running them and some of the systems are running either pps-mega or sgs. Might oc a tad more but not now as they are all running and reporting.
edit: looking like the gfn17-megas and gfn16 are currently getting lots of love |

Hmmm. Based on my 18 times (I can do apples to apples on the 770 and 1070)
770 2116-2118 sec
1070 1022-1063
I might think about moving the Kepler cards down to 17, but I'll probably keep the Pascal ones on 18.
What's with the YUUUGE spike in GFN18? It looks like in-process tasks temporarily went above 17 low and mega this morning.

Since we all have some benchmarks, time to share mine:
i7 6700k @ 4.0 GHz, MSI GTX 1080 Gaming X, DDR4 2x4Gb 2600 MHz running at 2133 MHz
- PPS Mega -> 3400 sec/unit with 4/4 physical cores running
- SGS -> 590 to 600 sec/unit with 4/4 physical cores running
- GFN22 -> 44.3 hrs/unit with 4/4 physical cores running PPS Mega/SGS
i3 6300 @ 3.8 GHz, Gigabyte GTX 1060 3 Gb, DDR4 2 x 4Gb 2600 MHz running at 2133 MHz
- PPS Mega -> 3360 sec/unit with 2/2 physical cores running
- SGS -> 600 to 605 sec/unit with 2/2 physical cores running
- GFN22 -> 73.5 hrs estimate with 2/2 physical cores running PPS Mega/SGS
i3 6100 @ 3.7 GHz, DDR4 2 x 4Gb 2600 MHz running at 2133 MHz
- GFN20 -> 31.95 hrs with 2/2 physical cores running GFN20 (CPU)
i7 3630QM @ 3.2 GHz, MSI GTX 660M 2 Gb, DDR3
- killed PPS Mega (CPU) and GFN20 (GPU) due to hyperinflated run times
- now running GCW Sieve (CPU) and PPS Sieve (GPU) |

Changed my tactics - went all out on gfn 16's for a few. |
|
|
|
|
|
I'm not sure what the time setting for getting new tasks is but I think it must be somewhere close to 2 minutes before current task is done to ask for another? Anyway, as fast as these 16's run, even with a 0 cache I have 2 tasks waiting most of the time. Not always but have noticed it a lot. Might just be me. |
|
|
|
|
|
Rick, it is indeed two minutes and this is something I have noticed with all my tasks as well.
Since it applies equally to everyone, I would not say you are at any sort of disadvantage since we all have that two-minute penalty. |

From the task status page, current daily completion rate:
17 Low: ~2670
17 Mega: ~4750
18: ~3500
Average daily completion rate over past year:
17 Low: ~3350
17 Mega: ~1450
18: ~832
Wow.

well it appears for me it does.. however the 770 is only running gfn16 and the 2 970's are running pps-mega on the cpu's as well.. shouldn't make that much of a difference but it looks like it does. like I said a while back 970's are a waste of time, money and space. But since I have 2 of them... |

Figured I'd post a few times from my GTX 760 to make me want to get a 1070 or 1080 sooner...
GFN 17 Mega: ~1600sec/wu
GFN 18: ~2600sec/wu
GFN 19: ~9700sec/wu
The 1060 times Scott Brown posted are a little over half my times for GFN 18... And probably uses much less power.
Good luck everyone! I haven't run GFN much before this, as my GPU is horrible at GFN, and it was always running PPR12M, and hasn't been running much since then.. But with the below freezing temperatures, heat isn't a problem so I'll run it for a good while.
What are you all switching your GPUs to on mountain stage day?

I have been working on it since the start of the challenge wiith PPS Mega, SGS, GFN 20 and GFN22.

If you have a way to discount RR's find, I am all ears! :-)

Yes, you are. :)
There's a big link on PrimeGrid's front page "Tour de Primes" (just above the big clock). Click on it. It leads to the main forum thread about TDP. There's also a link to the TDP leaderboards directly underneath the clock.

wow, how about that?
It seems that I always hit the primegrid page via "your account" in the boinc manager, so I did totally miss it. kinda not great that I'm in the middle of 400p manual sieving reservations, but I'll move to prime finding projects and see what happens! |

You have the option to cancel those if you wish. You will get penalised by the system for canceling them, but the penalty is small: You'll only be able to reserve 6 reservations simultaneously instead of the 10 you currently can reserve. That will eventually go back up to 10 as you complete future reservations, so it's temporary.

ok, so I've been hooked on this challenge and watching my work, and I have to ask: how do some of you guys nail primes so quickly? I understand the guy who found the mega was very lucky.. do you just crunch zillions of WUs or what? for GFN, my records show about 10k WUs and two found primes... for PPS, I have about 5k and one prime. is that about average, or shall I go out and find a few leprechauns to increase my luck factor?

Some people have a lot of computing power available. The more tasks you can run, the more primes you're going to find.

The TL;DR is, to paraphrase Thomas Jefferson (to whom attribution seems most frequent), the harder I work the luckier I get.
But its a bit more complicated than that. Task selection makes a big difference. I have my faster CPUs on PPS-Mega, where they are substantially less likely to find a prime than if they were on SGS or PPSE. My GPUs are on GFN18 and GFN22, where they are very unlikely and extremely unlikely to find a prime, respectively. The tasks I am running also take longer, so I get a "double whammy" effect based on those choices.
Of course, if I do hit a prime on any of those, it has a pretty good chance of being the largest found during the challenge.
In the database for my user account, i am showing 6183 SGS, (from my slower cpus), 3584 GFN18, 2318 MEGA, and 123 GFN22 (all including in-progress and pending units).

shall I go out and find a few leprechauns to increase my luck factor?

I'd say you should but Lord Rat might not appreciate being found.. or maybe he would depending
Finding a prime is a lot of luck and a lot of patience. Having more resources is definitely a plus but NOT always a guarantee. You'll see lots of primes found by older and/or slower systems. And as Zman said it also depends on the sub project you run. AP is a great one for just finding primes as is GFN15 but both are too small to count for the TDP.
I know you will prevail ! |

I lost about 3 hours crunching time today due to, get this, I had to start flipping circuit breakers off when one of my smoke detectors went berserk (they are wired into the house electricity, not on batteries). Sadly they are on the same circuit as my 3770K. Had to immediately run to make a dinner engagement. Came home, flipped things back on, and all seems well now. I suspect something related to high humidity. Maybe I should stop taking showers :-)
Unlikely this will affect my expected "zero" score in the Tour.

ok, so I've been hooked on this challenge and watching my work, and I have to ask: how do some of you guys nail primes so quickly? I understand the guy who found the mega was very lucky.. do you just crunch zillions of WUs or what? for GFN, my records show about 10k WUs and two found primes... for PPS, I have about 5k and one prime. is that about average, or shall I go out and find a few leprechauns to increase my luck factor?

Tim, if you will feel better: I can say that I am here for years, still, found nothing more then 589.000 digit prime ( and even that one is found outside Primegrid on PRPNet).
And yes, person come with old Sempron, run 21 task and found mega priem ( I sow this with my own eyes)
But look that in the other side:nobody on Earth doesnot know where primes are. So maybe candidates you are crunching now is primes. Live in hope, and glory ( about find prime) will come...
But if you wont your first prime ASAP: stick to SGS and PPSE. Task are short, so you can process many of them in short period of time. One will be prime.

How is this for ultimate irony and where I am waiting on Zimmer to confirm a GFN22 task rather than the other way around: http://www.primegrid.com/workunit.php?wuid=511853979. |

Wait few days and that will be over :)
SoB is much difficult for waiting :)

With Zimmer, no need for a few days. :-)
As for SoB, I know very well since I had to wait a couple of months for some of my units to verify. |

It should be done soon-about an hour and 4 minutes....
[Edit] You should be all set. Completed and validated :) |

That is true nerve exercise ;)
Your candidate is just little more above 20M digits: if that is prime, then can stop right now: and wait few years: nothing will be changed ( so fast) :)

Congrats to RR for getting on the scoreboard with his GFN16 find.
Houston, we have a (serious) problem. One more for RR ..... RR: 2, AA: 0 :-( |

If you want find more primes, you should stop crunching GFN22 units ;) |

Woot!
AA is working toward a very large prime. I hope he finds one.
edit: have my 1070 on gfn17 and all the others on gfn16 |

Nice to see one of my dinosaurs snag one:
http://www.primegrid.com/workunit.php?wuid=513614874
TLDR, I got it second (by 18 seconds) but finished ~19.5 hours ahead. My machine is running an E5520. Run time is more than double his, and he has HT on on his 5820K. He also apparently has a cache (51 SGS tasks in progress, 51 PPSE). |

Zimmer, how long does it take for the official confirmation to show up? ;-) |

It shouldn't take long :) |

Some folks don't seem to care about a large cache on prime projects.
My short attention span has kicked in. After the 19th will cut and run on this. |

I've switched CPU prefs over to PPSE in preparation for the "mountain stage". This should give me enough time to burn off my ongoing TRP-LLR work before then. 00:00 UTC Feb 19 start. Go AtP!
