Primegrid Challenge Series

They are visible now, I think it is a corrupt driver install. I noticed this morning when attempting to get it to run again tiny orange dots started popping up on the screen, they go away as soon as I shut boinc down. ... will try to download and re-install this evening.

The driver is the correct one but it might be a corrupt install. I believe from your description it may be overheating. Download and run GPU-Z and check your temps. It could be as simple as blowing out the heatsink, a failing fan or a power problem.

I got one of the HD 4850's running with the new 10-12 driver released today w/o the need for the app_info file on Win7_64, now if it will work on XP_64 I'm in business. I will try one of the HD 5770's with this driver too and report back.



/edit/ On the 5770 I at first thought it was another failure ... 1st 3 wu's errored after only 3 or 4 seconds, but the fourth one is still running. checked the failed wu's and all have multiple failures.

Next question, how are cpu's like on this project, worth the effort?

Ya how long are CPU WU's
What are CPU points worth

Very long. 12 to 28 hours on a q6600. Flate rate credit of 2312 per WU for the PPS seive WUs. The problem is that only WUs downloaded and returned during the challenge count. That means that only work downloaded after 18:00 utc 18 Dec. (13:00 eastern time) will count. It does not help if you have a large cache. I've set mine to connect every 0 days and maintain additional work for 0 days.

We're at #31 for total credit and closing rapidly on Boinc@heidelberg.

Tried running the sieve jobs on a CPU, they are quite slow.
Probably 12 hours on a q6600.
Assuming you have 4 jobs running in parallel then it should be possible to do 8 a day.
Around 18K cobblestones per q6600/day

Long term i wouldn't use a CPU to sieve, video cards do it so much better.
However for the duration of the challenge it would be worth doing if someone had lots of CPU's

Everone set for the PG challenge ?
ATI cards behaving now ?

I fully expect to be beaten by BigRed, if not questions will be raised

All cards running and one more little trick to setup tomorrow.

ATIs are fine but there is a possible CUDA problem. If you have the Cuda 1.36 application running, you need to do a reset to get the 1.37 application.

I'll do my best to make as much credit as possible.
After all this is a team effort.

I see that you brought the big guns. Not much chance of me beating that.



With all the prepration for the challenge the team is now at #26 for total credit.

Next victims: Dutch Power Cows and TeAm AnandTech.
