If you do proper cuda error checking in your code, you can retrieve that 0xb error that is being reported from a
cudaGetLastError call, and pass it to a decoder (
cudaGetErrorString) that will tell you something more meaningful.
CUDA runtime API error codes are enumerated in
driver_types.h, which on a standard linux install will be in
/usr/local/cuda/include Search on
cudaSuccess which will be the first enumerated type (i.e. 0) then continue on until you find your error number.
In this case
0xb (= 11) refers to
/** * This indicates that one or more of the parameters passed to the API call * is not within an acceptable range of values. */ cudaErrorInvalidValue = 11,
