For 4 ACEMD 3 tasks, I got this error. That's the standard and expected error on acemd tasks for restarting calculations on a different device that what the task was initially started on. You didn't post the host so assume it has multiple cards of different type. Unless you have all the same type of cards i.e all 1080's for example, it is best to not pause or stop the calculations of acemd tasks. | |

you (or something) interrupted the task and it restarted on the other GPU. 21:51:33 (21892): wrapper (7.9.26016): starting it started on device 1 at 21:51, then something happened (either you shut off the computer, or rebooted it, or BOINC interrupted the task to do something else, and the task restarted on device 0 at 11:16. i think this has always been the case with acemd3. they don't tolerate that. your host identifies the best GPU as the GTX 1080, and you have two GPUs in the host. but are they both the same? if not, then that's the problem. sometimes it will restart OK on a different device if the GPUs are identical, but i've seen cases where even restarting on a different identical device causes this error. the best bet is to not interrupt these at all. are you turning your computer off at night? dont do that. are you running other projects? maybe suspend them while GPUGRID is running, or set boinc to not switch tasks do you have BOINC set to suspend GPU tasks when the computer is in use? turn off that setting. did the computer crash due to some instability or overheating? investigate and remedy that problem. ____________ ![]() | |
