Debugging CUDA Programs
The TotalView CUDA debugger is an integrated debugging tool capable of simultaneously debugging CUDA code that is running on the host Linux-x86_64 and the NVIDIA® GPU. CUDA support is an extension to the standard version of Linux-x86_64 TotalView, and is capable of debugging 64-bit CUDA programs on Linux-x86_64. 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
• All Linux-x86_64 host debugging features are supported, except for ReplayEngine
