Welcome to another year of the PrimeGrid Challenge Series! The good news this year is that there are likely to be at least two challenges where we can use GPUs. The bad news is they've hardly said anything about any of the challenges! :colbert:

But they're starting us off with the best challenge of the year for finding primes, the Year of the Rabbit Challenge. Edit: They finally posted a race thread. It will start February 3 at 18:00 UTC and run for three days.

What you need:
  • One or more fast x86 processors. (Even slow ones will do!)
  • Windows, Linux, or MacOS 10.4+. (Linux may be up to 10% faster, but shouldn't be if they get the new wrapper uploaded in time.)
  • BOINC, attached to PrimeGrid (http://www.primegrid.com/).
  • Your PrimeGrid Preferences with only "Proth Prime Search (LLR)" selected in the Projects section.

What won't help (but won't hurt either):
  • A 64-bit OS.
  • A large amount of RAM.
  • Any video cards. (I tried to get LLRCuda working, but it just won't handle these numbers. Sorry. :()

This challenge starts February 3, the Chinese New Year. Work not downloaded and uploaded within the challenge will not be counted. Should you not be able to be in front of one or more computers at that time, just set their queue level very low (0.01 days). This also makes it more likely that you will be a prime finder rather than a double-checker.

Welcome and good luck to all! :) Now let's all...

...hop to it! ;)

Thanks for the heads-up and info. Although I am away from home (and the computing farm), I'll try to ser up the computers to take part in the race.

Does this mean that I'm going to have to find another project for my 9800. I'm guessing that the PPS Sieve tasks will not count for the race.

:(

The best thing you can do with your 9800, for now, is to set your PrimeGrid preferences to (1) PPS LLR, and (2) "Send work from any subproject if selected projects have no work". Since there is no GPU work for PPS LLR, you'll get GPU work from the (now two) GPU-enabled projects, PPS Sieve and CW Sieve.

The bad news is that (1) you can't get just PPS Sieve work anymore, and (2) if the server runs out of PPS LLR work you might get a month-long Seventeen or Bust WU or something. So you should keep an eye on that machine.

Edit: A second option is to have two profiles, one CPU only and one GPU only. Load up on WUs from one, then switch to the other and they'll keep running. The problem with this is that PrimeGrid has limits on in-progress tasks, so I don't know if you can load up enough work for even half a day.

Thanks, Ken:thumbsup: I had been wondering the same thing.

I'm confused!

The Challenge Series calendar says Feb 14-17 and the count-down indicates a little over a day before the start.

Hmmmm.... Edit again: that is last year's calendar. I'm more confused than I thought!

Edit: @Ken: It works almost fine. I somehow got one pps sieve of 58 hours instead of the GPU version.

Apparently, I got one of the CW GPU WUs because I now have a few credits in that project.

Third edit: I got another cpu wu for pps sieve, again for 58 hours.

1. The current Challenge Series calendar is for last year. The Chinese new year moves back every Gregorian calendar year.
2. Make sure you checked only PPS LLR (not Sieve) and "Send work from any subproject if selected projects have no work".

Oddly one of my ubuntu rigs is giving me mesages that PPSLLR wu are not available for my type of computer. It has been crunching boincsimap for a long bit now and I don't remember changing anything from the last primegrid challenge. Any ideas?

If it's a 64-bit rig, type "sudo apt-get install ia32-libs".

The race starts in less than two hours!

PPS LLR races are always the toughest on the server. So far it's going relatively well: not too many HTTP errors, although uploads and downloads are going slower than I've ever seen! At this point, everyone should probably buffer at least an hour or two (0.5-.1 days) of work, just in case we do get too many HTTP errors.

I guess Petrus hasn't gotten any computers set up for this yet.

Well, I have set up the computers, they are crunching as well ... but my ISP is down since some hours ago.
Can't do anything about that. Also I am away from home and nobody at home knows how to set ut the ADSL to our spare ISP.
According to the folks at home the script worked ok, but all comps have lost ISP-service 25 minutes before the race started ...
I am back tomorrow ... we will see if the ISP got it's act together!

Welcome to the race, petrusbroder. Sorry to hear about your dumb ISP. And the backup ISP failed, noo! I take it you can set up the ADSL though, right? :)
At least the clients downloaded work after 18:00UTC, with any luck.


biodoc and kimmyl just whizzed past me *waves* ;)

Well crunched! :thumbsup:

Edit: Sorry my stats aren't as pretty as Ken's. :(
Edit again: I used more smilies, however! :D

Hopefully Peter's network problems are resolved soon! :)

We're in 13th place just behind our friends at KWSN! ;)
