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. Save the file as "app_config.xml" into your WCG project folder.Total CPU Threads / Total GPU WU = cpu_usage The default value is 1, but if you want to run more GPU WU than you have CPU cores edit it accordingly. cpu_usage: This specifies the % use of CPU threads per GPU WU.Set this according to how many WU you want to run per GPU. gpu_usage: This specifies the % use of the GPU per WU.Best to set this to the number of total HCC1 WU your computer will be doing at a time. max_concurrent: This specifies the maximum number of WU the app can run at a time.Edit the following according to your setup:.

This is achieved by creating a file called app_config.xml to detail how to use your hardwareīefore creating the app_config.xml file you will need: This can increase the output of both your PPD (point per day) and the runtime per day. This guide will show you how to get better performance from your GPU by running more than 1 WU at a time. This is much simpler, with no AMD/NVIDIA specific code and avoids a lot of issues we encountered in the pastīy default World Community Grid is setup to run a single GPU WU on your machine. Please check the prerequisites list below and use the new setup guide. Users of app_info.xml method: This method will not be supported by WCG in the future.
