1) Message boards : Problems and Bug Reports : FGRP #3 feedback (Message 112769) Posted 12 Jan 2014 by zablociak Post: Now everything runs smoothly and without "validate error" problems, on both Nvidia GTX560, AMD HD 7970 and different CPUs (Phenom II X4, i5 Ivy and i7 Lynnfield). I hope we can test production version of FGRP #3 soon (I mean "real" samples with full GPU load). GTX560 HD7970 Regards Luke
2) Message boards : Problems and Bug Reports : FGRP #3 feedback (Message 112767) Posted 5 Jan 2014 by zablociak Post: My host https://albert.phys.uwm.edu/results.php?hostid=9923 (GTX 560 non OC'd with 301.42 driver, i7 860 @2.8Ghz) calculated 29 FGRP#3 FGRPopencl-nvidia tasks with av. of 650 sec of Run/CPU time (A@H was the only project being calculated at that time). All WUs finished without error, but 23 of them validated so far as "Validate error" and 6 are still pending. Can you take a look into these results? Regards Luke
3) Message boards : Problems and Bug Reports : validation inconclusive (Message 112333) Posted 29 Jan 2013 by zablociak Post: Yep, all my invalid WUs are coming from "Gravitational Wave S6 LineVeto search (extended) v1.04 (SSE2)" running on Xeon E5620 CPUs (8 invalid / 674 valid / 532 pending). It seems to be Xeon-related problem.
4) Message boards : Problems and Bug Reports : Too much credits for Gamma-ray pulsar search #2 WUs (Message 112305) Posted 17 Dec 2012 by zablociak Post: For me runtime is almost equal to CPU time (Intel(R) Xeon(R) CPU E5620 @ 2.40GHz http://albert.phys.uwm.edu/results.php?hostid=5406): Completed and validated 3,818.44 3,726.36 337.00 Gamma-ray pulsar search #2 v0.01 Completed and validated 3,730.78 3,675.30 337.00 Gamma-ray pulsar search #2 v0.01 Completed and validated 3,810.77 3,721.31 337.00 Gamma-ray pulsar search #2 v0.01 Completed and validated 3,761.98 3,671.61 337.00 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,749.19 2,665.45 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,657.27 2,649.75 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,686.08 2,675.86 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,719.69 2,657.48 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,670.48 2,650.11 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,687.42 2,652.78 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,698.30 2,655.63 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,663.92 2,639.92 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,634.16 2,619.80 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,625.44 2,616.44 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,662.67 2,653.94 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,673.80 2,664.09 235.90 Gamma-ray pulsar search #2 v0.01 Completed and validated 2,681.30 2,668.28 235.90 Gamma-ray pulsar search #2 v0.01 And I'm over 200 k credits/day in Albert, which is (a little) crazy for CPU-only crunching. I was barely able to hit 25 k credits/day in Leiden@home lately. Luke
5) Message boards : Problems and Bug Reports : Too much credits for Gamma-ray pulsar search #2 WUs (Message 112303) Posted 17 Dec 2012 by zablociak Post: In my opinion Gamma-ray WUs give too much credits/WU (ca. 7 times). On one computer: Gravitational Wave S6 LineVeto search (extended) v1.01 (SSE2) - 0.013 cred/sec Binary Radio Pulsar Search v1.30 - 0.013 cred/sec Gamma-ray pulsar search #2 v0.01 - 0.088 cred/sec. Cheers Luke

7) Message boards : Problems and Bug Reports : [New release] BRP app v1.30 (new 64bit versions) (Message 112258) Posted 29 Oct 2012 by zablociak Post: Hello! It looks like we've run out of samples to crunch. Now I get only resents. There are also some serious problems with a few WUs, they all end with a "Validate error" http://albert.phys.uwm.edu/workunit.php?wuid=138296 Do you really think it is necessary to set the "max # of error" so high (20)? Regards! Luke
8) Message boards : Problems and Bug Reports : [New release] BRP app v1.30 (new 64bit versions) (Message 112252) Posted 20 Oct 2012 by zablociak Post: Hi! I crunched some BRP CPU WUs on my core i5-3450 @3.10 GHz (Win7, 64b). Here are the results: - einsteinbinary_BRP4_1.30_windows_x86_64 - 21654 s (+/-324 s, N=14) - einsteinbinary_BRP4_1.22_windows_intelx86__BRP4SSE - 26739 s (+/- 546 s, N=14) I hope I'm not comparing apples and oranges, but it seems to be a ca. 19% improvement. There were no problems during the crunching process, everything went smoothly. Bye! Luke
