1) Message boards : News : Production 2013 (Message 25450) Posted 16 Feb 2013 by boroda3 Post: First GPUs; this NOT easy. SixTrack is in Fortran. Almost all GPU support is in CUDA for C. What is in the Fortran, which is not in the C? Unique Scientific Library? All other code translates to the C without any problems. Don't use CUDA please. CUDA - for NVIDIA card only, not for ATI and other. Use OpenCL instead, it is the same for both.
2) Message boards : Number crunching : How is the SSE3 thing coming along? (Message 24344) Posted 14 Jul 2012 by boroda3 Post: I have SSE2 and PNI WU's. Task / Run Time / App 4148834 / 15,002.69 / SixTrack v444.01 (pni) 4148831 / 14,962.90 / SixTrack v444.01 (pni) 4148621 / 15,884.89 / SixTrack v444.01 (pni) 4168474 / 887.66 / SixTrack v444.01 (sse2) 4168472 / 1,394.16 / SixTrack v444.01 (sse2) 4168470 / 1,023.10 / SixTrack v444.01 (sse2) BOINC 7.0.28, Win7 x86, AMD Phenom II X4 955 You say, that SSE3/PNI faster? Hmm... Again problems with optimization for AMD processor? Don't use Intel compiler.
3) Message boards : Number crunching : Maximum elapsed time exceeded (Message 24001) Posted 25 Jun 2012 by boroda3 Post: No Athlon. Phenom II X4 955. Passed very strong test. But task protocol says: <core_client_version>7.0.28</core_client_version> <![CDATA[ <message> Maximum elapsed time exceeded </message> <stderr_txt> Unhandled Exception Detected... - Unhandled Exception Record - Reason: Breakpoint Encountered (0x80000003) at address 0x752B3E2E It's not like a performance problem. --------------- PS to Message 23998: Crashed tasks are 3653125, 3653119, 3653107, 3653085

May be it is not error of my system (Phenom II X4 @ 3.3GHz) - but wasted time. I think the other tasks of this party can also be immediately disposed of, not to be wasted CPU.
