Trouble shooting

The reasons for a CUDA kernel launch fail

If there are insufficient registers or shared memory on each SM to process at least one block, the kernel launch will fail.

Memory check: compute-sanitizer –tool memcheck ./a.out

Shared memory race check: compute-sanitizer –tool racecheck ./a.out

Initialization check: compute-sanitizer –tool initcheck ./a.out

Synchronization check: compute-sanitizer –tool synccheck ./a.out
