Is there something like the unix command “top” for CUDA?

Question

More generally, how can you check the current status of your GPU? (current number of threads running, memory state, and so on).

(I'm using linux, so Windows-only solutions, while interesting, won't solve my problem)

Answer 1

If you are using Nvidia, you could use the Visual Profiler utility included in the CUDA Toolkit :

For Radeon, perhaps the ATI Tray Tools can do the same (but I am not sure).

Answer 2

I use GPU-Z.
