TotalView® for HPC Getting Started Guide : Getting Started with TotalView Products : Debugging CUDA Programs
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 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 host debugging features are supported, except for ReplayEngine
