CUDA-MEMCHECK

When I try to run CUDA-MEMCHECK, this happens:

  Code:
CUDA-MEMCHECK ./BandMatrixSolver 1024.0513
-bash: CUDA-MEMCHECK: command not found


Where is CUDA-MEMCHECK located?

Re: CUDA-MEMCHECK

Lowercase: cuda-memcheck. (It's located at $CUDA_INSTALL_PATH/bin/cuda_memcheck)

Re: CUDA-MEMCHECK

I have the following error message through cuda-memcheck
  Code:
========= Out-of-range Shared or Local Address

this is when I am trying to copy the result from device to host.

Any ideas?

Re: CUDA-MEMCHECK

have you got to the bottom of this?
there should be a line number that indicates where that occurs.
Have you looked if you read out of bounds?
If you use a pointer that is healthy?
