cuda-gdb: single GPU controlled by separate thread unsupported?

I noticed that in the known issues for cuda-gdb, it says that “Multi-GPU applications are not supported”. Does this also mean that single-GPU runs where the CUDA runtime API calls are made in a thread other than the main program thread are also unsupported?

I was trying out cuda-gdb with HOOMD and breakpoints set inside kernels wouldn’t break, while in small standalone programs, everything seemed to work fine.

hmmmm, unsure. I’m going to go with “probably” but I’ll double check to make sure.
