NVIDIA CUDA Debugging Overview
The TotalView CUDA debugger is an integrated debugging tool capable of simultaneously debugging CUDA code that is running on the 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 systemsSupport for directive-based programming languagesSupport for host debugging featuresRequirements:
The CUDA SDK and a host distribution supported by NVIDIA. For SDK versions and supported NVIDIA GPUs, see the TotalView Supported Platforms Guide.
