I'm having problems running MW because my AMD cards are unalike, and am hoping for some sort of fix or workaround. Card 0 runs both single and double precision very fast. Card 1 runs great single precision, but does double precision at a glacial pace, less than 1/7 as fast as card 0. If card 1 is running MW, it's being wasted, I'd like to restrict it to one MW job on card 0. I tried inserting code like this into my app_info.xml: <max_concurrent>1</max_concurrent> <coproc> <type>ATI</type> <count>0.4</count> <device_nums>0</device_nums> </coproc> This failed to either limit it to one MW job at a time, or to keep MW restricted to card 0; it ran multiple copies on both. Does anyone know how to get it to do what I need? It seems like it'd be a relatively common problem, but I'm not finding much. |

Try something like this instead: <cc_config> <options> <use_all_gpus>1</use_all_gpus> <exclude_gpu> <url>http://boinc.fzk.de/poem/</url> <device_num>1</device_num> </exclude_gpu> </options> </cc_config> It needs to be in the ProgramData\BOINC directory. Change the poem stuff to milkyway stuff. |
