PrimeGrid World Expo Challenge April 23-May 1

[Ken g6]

Welcome to the PrimeGrid challenge booth at the World Expo! There are only two challenges at the booth, but that's one more than usual. Like last year, there will be two projects, short GFN WUs, and "World Record"-sized WUs. Unlike last year, both projects will be counted together toward your score. World Record work gets a bonus - if you can complete it in time. The race is half the length it was last year, so only the fastest GPUs will be able to do a WR WU.

What you need to participate:

• One or more stable GPU(s). They can be either AMD or nVidia, but they need to be able to do double-precision computation. Scroll down to the bottom ofthis page for a list of known working GPUs on GFN, as well as their relative speeds. If your GPU is not listed there, you may be SOL. (Single-precision Only Level. ) Be sure not to overclock too much. If any of your PPS Sieve WUs errored out in the last race, lower your overclock for sure.
• And/OR you can run one or more fast, stable x86-64 processors with a 64-bit OS. There is no 32-bit CPU work. Intel CPUs with AVX will have an advantage. I'm not sure other CPUs will even have time to complete one WU.
• Windows, Linux, or MacOS 10.4+.
• BOINC, attached to PrimeGrid (http://www.primegrid.com/).

What might help:

• Faster RAM for your CPU work. (But, again, it has to be stable!)
• Ken's WU Juggling Guide for those using multi-core CPUs.

What won't help (but won't hurt either):

• A large amount of RAM.
• Any really old video cards or Intel video cards - though you might want to use them for your display while newer cards crunch.

This challenge starts on April 23 at 18:00 UTC and runs for 8 days. Only WUs downloaded after the start of the challenge and completed before the end of the challenge will be counted. Should you not be able to be in front of one or more computers at the start time, try one of the scheduled start methods from the strategy thread (for Linux or Windows). Network connection time options may also be useful - though they depend on your computer's clock being correct, so set the start time a few minutes late.

Welcome and good luck to all! :thumbsup:

I'll be in this race --- don't know how much it will help ...

 

[Ken g6]

There is no 32-bit CPU work.

Peter, did you ever update your OSes to 64 bits? :hmm:

 

[petrusbroder]

Yupp, 5 of 7 are win-7 or win-8 64-bits, and the other two are dual boot Win-XP/Ubuntu 64-bits ...
No prob there ...

 

[biodoc]

I'll be in with my GPUs but I think I keep my cpus on Leiden and/or Edges.

 

[GLeeM]

That might be a good idea for me too. Otherwise I have to lower the OC.

 

[Ken g6]

Otherwise I have to lower the OC.

I use ThrottleStop to lower the clock on my laptop. I imagine you could do the same to temporarily lower your overclock. (Unless you're on Linux in which case maybe cpufreq-set?)

 

[zzuupp]

I've put my preferences on the on deck circle.
Updated the app-info on the red card, it's doing a test run at the moment.
Now, I just have to remember to hit the site tomorrow after lunch to get the green cards going. :biggrin:

The green ones will do shorties. I think the red card can finish a WR unit.

 

[GLeeM]

And we're off!

I have three Genefer World Record WUs running on GPUs.
And five Genefer CPU WUs running - three on the 4770K and two on the 4790K (without lowering the OC )

 

[petrusbroder]

I am off too - 8 WUs are running on GPUs - none on CPUs ...

 

[VirtualLarry]

I'm in with one 7950.

In the event you don't finish a WU before race's end, is it safe to assume you still get points in BOINC, although they don't count for purposes of the race?

Absolutely!

The challenge is really just leaderboard for who gets the most credits in a certain subproject (or subprojects) during an 8-day period.

 

[waffleironhead]

Have a great race everyone! I'll be cheering from the sidelines.

Wow, fourth place! :thumbsup:

Now, I recently noticed in the PrimeGrid race thread that they're running out of the shorter GFN WUs. They don't think they'll run out before the end of this race, but they might. I would therefore suggest to anyone who has completed work already (that's you three) that you should do the larger GFN WUs instead, on the machines that already completed work.

 

[TennesseeTony]

I couldn't get a world record unit on my fastest machine. The other two picked one up instantly upon joining the project. Odd.

Anyway I'll toss a few points (assuming successful completion) into the TeAm's pot and then suspend most GPU computing for the summer.

Wow! 4th place! Nice work fellas!

 

[biodoc]

I'll finish one more short WU on each of my GPUs and then move to WR WUs.

 

[petrusbroder]

We are doing good! We have three TeAm members among the top-15 and are #5 in the team race! I am surprised ...

Me too! Might just be that the big guns are doing World Record-sized WUs, though, and haven't shown up yet.

 

[petrusbroder]

Must be so ... aren't those WUs worth some 300K points?

 

[biodoc]

I'm not sure how many points the "big boomers" are but they carry a 50% bonus.

GLeem has 3 going since the start of the race. I have 3 going but the first won't be done for another 65 hours.

I'm going to pull the 4850 off my 1090T and install my GTX570 and 660Ti to get them crunching little boomers.

 

[petrusbroder]

I have some 2 - 3 little boomers coming up within a few hours ...
The GTX 570-ies and 660Tis are good at this ...

OK, 2 more small boomers delivered - up in the stats in the coming hour.

 

[TennesseeTony]

I'm going to pull the 4850 off my

All 4 of my 4850's erred, so I pulled the plug on them.

 

[GLeeM]

GTX570 and 660Ti

According to Ken_g6's chart linked above, these are better than my GTX970 which is doing one percent per hour (33%).
The 280X is at 53%
The GTX780 is at 48%
The CPUs are at 80%(4770K) and 86%(4790K)
