2) Questions and Answers : Windows : Multi-GPU task takes longer than single-gpu task (Message 154) Posted 7 May 2011 by 3327 Post: Yep. All tasks on my dual 5870 machine take ~1-2 hours. On my single 5870, they take ~15 minutes. really strange! but DA's bright new credit-system has decided to compensate for that and is granting a freaky load of credits for those WU's now.. uh, really? 49194 43088 7 May 2011 \| 13:29:48 UTC 7 May 2011 \| 14:33:03 UTC Completed and validated 3,786.47 3,484.83 49,620.57 Distributed.net Client v1.01 (ati14) 49132 43026 7 May 2011 \| 13:29:48 UTC 7 May 2011 \| 15:37:19 UTC Completed and validated 3,847.45 3,457.91 50,410.69 Distributed.net Client v1.01 (ati14) 48153 42215 7 May 2011 \| 11:10:49 UTC 7 May 2011 \| 12:24:54 UTC Completed and validated 4,433.80 1,535.66 57,499.16 Distributed.net Client v1.01 (ati14) 48069 42142 7 May 2011 \| 11:10:49 UTC 7 May 2011 \| 13:34:59 UTC Completed and validated 3,895.79 2,959.86 51,030.92 Distributed.net Client v1.01 (ati14) 46009 40162 7 May 2011 \| 7:01:43 UTC 7 May 2011 \| 9:47:34 UTC Completed and validated 4,835.84 1,024.91 62,713.01 Distributed.net Client v1.01 (ati14) I think DA is on to something. :) I'll see if a WU completes on this end. thanks.
3) Questions and Answers : Windows : Multi-GPU task takes longer than single-gpu task (Message 148) Posted 7 May 2011 by 3327 Post: Tasks take one hour on my HD 5970 @ 770/600. Use 2 full CPU cores. Stderr output shows application is restarting every 5 minutes. With no CPU projects running GPU usage is 99% but temperature of core and VRMs is low and power draw is also low. The GPU engines are revving at full speed but have almost no torque. Xeon W3520 @ 3.1 GHz, Win 7 64, BOINC 6.12.22. Cat 11.4 Preview (1.4.1353). I made my first attempt, last night, with moowrap--2x5870s, hesitant because of the infamous hanging cpu problem some of us experienced with dnetc. every WU I tried, 4, immediately jumped to 14.814% with 25% cpu, 2 threads or 1 core, of an i7. the first error-ed after I suspended and resumed, but I aborted the others at ~15min, still at 14.814%, given I see numerous machines with 2x5870s completing WUs in~600secs. kashi, I have the same indications, low core and vrm temps, yet both gpus (950/1350) supposedly at 100%. I hope I am wrong, but there is no reason to believe this is not the same mess that plagued some of us trying to crunch dnetc. the only differences as I see them are that I have two threads, an entire core at 100% of an i7, and that I hav yet to get one that crunched or that I could tolerate until the end. the dnetc problem was sporadic and the WUs took at most 13min though most of the hanging with the cpu occurred after the gpus crunched the WU. the dnetc crew said there was nothing they could do about it, just a wrapper, and that distributed.net was not very helpful because so few had the issue or at least not enough complained about it. if you or anyone has ideas regarding the mysterious aspect of some dual 5870 machines that triggers the issue, please pass along the idea. win7 64b driver 11.4 2x5870s (oc'd but I eliminated that as the issue at dnetc) boinc 10.58 i7, 950 (not oc'd)
