I have a CUDA global kernel whose execution can fail if a condition is not met. Within that kernel I have something like:
if (condition is not met)
How can I trigger a CUDA error such that, on the host side, a call to cudaGetLastError() will return a CUDA error code.
If this is not possible, is there a workaround? I guess one can always perform an invalid operation on the device to force an error, but I am looking for a cleaner solution than that.
Thanks a lot,
