SETI MB CUDA for Linux

latni can you give us a link of a wu done by the gpu?
I'm suspecting that you get an out of memory error and the wu is then done in cpu, that's why you get 100% cpu utilization by the cuda app.

That is absoutly the case.. my first WU was finally finished by "GPU" and the error messages say MALLOC out of memory errors.. Looks like time for a better video card!

letni, what cuda app do you use? The 2.2 one or the one from the first post of this thread? The 2.2 one is very memory hungry. Try using the one from the first post of this thread and see if it helps. Mind you that it has a different name so you'll have to edit your app_info.xml accordingly.

That did the trick.. No 100% CPU usage anymore with the older binary.. Chugging away very fast now!! Hopefully no more computation errors!

letni I see you've already completed a few WUs with your GPU. Happy crunching! :)
