Hi,
Have 2 questions, please;
Are any projects for NVIDIA GPUs with less than 256mb of memory?
and how to limit/force/config those projects only to use the GPU, leaving another non-GPU projects (i.e. World Community Grid) using all CPU resources?
Thanks in advance

Collatz can use 128MB and less.

Technically, this isn't possible, since no GPU application runs on the GPU only. All GPU applications run on the CPU and use cycles of it. So you can't disable CPU use completely.

However, on the project's preferences page you will find options such as "Use CPU", "Use ATI GPU" and "Use Nvidia GPU". Depends on the project of course and whether or not they do have GPU applications and then which vendor's. There you can make your pick. By not enabling "Use CPU", you won't completely disable the CPU, you just won't get the CPU application and work for it from that project.

Hi Jord,
Thanks for the fast answer.
I have already Collatz working and I'll change the config to test it.
Thanks again.
