[New release] BRP app v1.23/1.24 (OpenCL) feedback thread
(Message 112070)
Posted 10 May 2012 by Ver Greeneyes Post: I cannot be sure that the cpu cores use different cores though... Your operating system's scheduler should take care of this unless you force specific applications to use specific cores. Basically the way it works is that applications/threads get 'time slices' from the OS scheduler, which is how it can run multiple applications side by side on a single core. Between time slices the scheduler might decide to continue to run a thread on a different core depending on how busy each core is - that's why you generally see even single-threaded applications using a bit of each core: because they spend about equal time running on each one. |

Posted 4 Dec 2011 by Ver Greeneyes Post: Maybe this is part of the issue regarding validation? Nvidia cards are still using the CUDA app though, not OpenCL. |

Computation error due to 'exceeded elapsed time limit'
(Message 111461)
Posted 1 Dec 2011 by Ver Greeneyes Post: For what it's worth, this seems to be either mostly or completely fixed now. Yesterday I still had about 10 WUs with computation errors queued up for reporting; today I had none. |

Computation error due to 'exceeded elapsed time limit'

Posted 23 Nov 2011 by Ver Greeneyes Post: To follow up on that, I just checked and I've gotten a lot of these computation errors. They all error out around 43:32 minutes, which corresponds exactly with the elapsed time limit of 2612.18 seconds from the error message. Ironically, going by the progress rate, the tasks should finish in a little under 48 minutes on my card. So it gets pretty close ... but not close enough. I just watched as a task was aborted around 91%. I'm suspending GPU work for now. |

Posted 22 Nov 2011 by Ver Greeneyes Post: Albert@Home BRP3cuda32 WUs occasionally seem to abort after ~45 minutes with a message like the following: 22/11/2011 16:18:58 | Albert@Home | Aborting task p2030.20100913.G48.73+01.03.S.b4s0g0.00000_3232_2: exceeded elapsed time limit 2612.18 (2800000.00G/1071.90G)I'm not sure what to make of this, since 45 minutes hardly seems like a long time and other units appear to finish without any problems. The host in question is here. |

Posted 20 Nov 2011 by Ver Greeneyes Post: Aside from not receiving any new tasks, I also can't seem to report the tasks I did manage to get. Was this intended? (they're all done by now) |
