Getting Started with CUDA

CUDA Error Reporting to CPU
All CUDA calls return error code:
Except for kernel launches
cudaError_t type
cudaError_t cudaGetLastError(void)
Returns the code for the last error (no error has a code)
Can be used to get error from kernel execution
char* cudaGetErrorString(cudaError_t code)
Returns a null-terminated character string describing
the error
printf(“%s\n”, cudaGetErrorString( cudaGetLastError() ) );
