Chapter 26 About the TotalView CUDA Debugger
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 hardware
• Set breakpoints, pause execution, and single step in GPU code
• View GPU variables in PTX registers, local, parameter, global, or shared memory
• Access runtime variables, such as threadIdx, blockIdx, blockDim, etc.
• Debug multiple GPU devices per process
• Support for the CUDA MemoryChecker
• Debug remote, distributed and clustered systems
• Support for directive-based programming languages
• Support for host debugging features
Requirements:
• The CUDA SDK and a host distribution supported by NVIDIA. For SDK versions and supported hosts, please see the TotalView for HPC Supported Platforms guide.
• Tesla, Fermi, Kepler, Pascal, or Volta hardware supported by NVIDIA
