![]() ATI/AMD GPU and GFAM (HCC GPU and GFAM CPU only) (example: Dual core CPU / 4 GPU WU = 0.5 avg_ncpus) Total CPU Threads / Total GPU WU Total = avg_ncpus If you want to run more GPU work units than you have CPU cores, change the 1.0 line to specify how much of a thread to use on average: ![]() This applies to both single and multiple GPU setups. (example: 1 / 4 GPU WU = 0.5 coprocessor count) 5 according to how many GPU WU you want to run at same time: (Please modify these to suit your system. If it doesn't exist, create it but the contents should have the following: To use more than one GPU in the same machine go to the BOINC data folder (normally: C:\Program Data\BOINC) and look for file "cc_config.xml". If you're using mixed cards by default BOINC uses the best one, and in some cases may not use all your GPU even if they're the same. Below is a simple list for ballpark figures: ![]() The best way to determine what works best for you is to find out how long a single WU takes then see how much longer it takes to complete multiple WU. Your mileage may vary, as factors like CPU speed and numer of threads have an impact on performance. For example if you have 8 CPU threads and want to use 2 for other projects you can set the value for HCC max_concurrent to 6. Max_concurrent can be used to limit the HCC WU. ![]() If you get an error about app_name not found in file, check the numbers you entered are correct and perhaps reset the project. I found that in switching from app_info it sometimes doesn't download any WU but once you hit the "update" button a few times it all looks normal. (Default Windows 7: C:\Program Data\BOINC\Data\projects\ (Default Windows XP: C:\Documents and Settings\All Users\Application Data\BOINC\Data\projects\ Ĭheck the event log (ctrl shift e) for any errors.
