Seti@Home now uses CUDA

**RicheemxX** · April 9th, 2009, 11:18 PM

Just wanted to pass along the information for anyone running Seti@Home. If you have a newer NVIDIA based GPU you can now use CUDA to crunch faster. You'll want to make sure you are running the latest NVIDIA drivers as well as the latest BOINC client.

For more details checkout the boinc cuda support page
Download and install the latest boinc client.

On a side note, if you have a qualifying GPU and the latest drivers the client will automatically report a CUDA device and will download work units designed to run on CUDA. This can be troublesome if you are running other CUDA based projects like F@H. It can also lead to some lag so you'll need to change the settings.

In the older clients the options are missing so you'll need to d/l and install the new client. From there you can run the preferences and disable "use GPU while computer is in use". That will allow you to run F@H or another CUDA based project on your GPU while running Seti on your CPU's (as I do). It will also help if you are experiencing lag or other issues because of CUDA using up too many GPU cycles.

do they also have this for ATI cards?? As they've shown that ATI cards can do some very nice crunching as well

AFAIK they are working on ATI support but at this time no its only setup for NVIDIA cards and cuda. They don't have any official word on support but they had a few comments in the cuda forums
