Information about non-active warps

Hi
Is there a way to see non-active warps in cuda-gdb? With info cuda warps I am able to see active warps on an SM, but with a given block/thread size, I am sure that there are more warps.

Hi @mahmood.nt,

Is there a way to see non-active warps in cuda-gdb?

Unfortunately it’s not possible. Warp are assigned to SM at the moment they start executing (and the assignment algorithm is internal to CUDA scheduler).

On a side note, you can use filter to see active warps on all SMs:

info cuda warps sm all

See CUDA-GDB :: CUDA Toolkit Documentation for more details.
