Enabling CUDA MemoryChecker Feature
You can detect global memory addressing violations and misaligned global memory accesses by enabling the CUDA MemoryChecker feature.
To enable the feature, use one of the following:
Select "Enable CUDA memory checking" from the Startup Parameters dialog box in TotalView, as shown in
Figure 265.
Pass the
-cuda_memcheck option to the
totalview command.
Set the
TV::cuda_memcheck CLI state variable to
true. For example:
dset TV::cuda_memcheck true
Note that global memory violations and misaligned global memory accesses will be detected only while the CUDA thread is running. Detection will not happen when single-stepping the CUDA thread.
