Debugging CUDA Programs
The TotalView CUDA debugger is an integrated debugging tool capable of simultaneously debugging CUDA code that is running on the hosts host system and the NVIDIA® GPU. CUDA support is an extension to the standard version TotalView, and is capable of debugging 64-bit CUDA programs. Debugging 32-bit CUDA programs is currently not supported.
Supported major features:
Debug CUDA application running directly on GPU hardwareSet breakpoints, pause execution, and single step in GPU codeView GPU variables in PTX registers, local, parameter, global, or shared memoryAccess runtime variables, such as threadIdx, blockIdx, blockDim, etc.Debug multiple GPU devices per processSupport for the CUDA MemoryCheckerDebug remote, distributed and clustered systemsAll host debugging features are supported, except for ReplayEngineUsing the CUDA debugger | |
