1) Message boards : Questions and problems : GPU tasking with APP CONFIG (Message 89998) Posted 11 Feb 2019 by MatLioLeC Post: Hello. i was wondering someone could help me with app config. I'm using boinc right now to mostly do Milkyway@home. i recently purchased a R9 280x with a decent FP64 rating and i've been messing around with the configurations. i think i found a very good configuration but it's a bit different see when i run one task at a time, i get it done in about 35-41 seconds. when i load up 4 at once i can get it done in an average of 32 seconds per task... when i load up 19 at a time, i get an average of 27 seconds per task! but theirs a catch.. it has to do the work in blocks. right now i'd like to set it to do 14 tasks at a time, it seems somewhat ideal. so 0.07 gpu fractions and i have it at .1 cpu. but to get it to do 14 task and not take on another b4 the 14 are all done. and once the 14 are done, it loads another 14 tasks.. i'm not sure what kinda line i would need to add to the APP_CONFIG. plz help with this little problem, thank you. <app_config> <app> <name>milkyway</name> <max_concurrent>30</max_concurrent> <fraction_done_exact/> <gpu_versions> <gpu_usage>.07</gpu_usage> <cpu_usage>.1</cpu_usage> </gpu_versions> </app> </app_config>
