Viewing the Kernel’s Grid Identifier

User_Guides : Classic TotalView User Guide : PART V Using the CUDA Debugger : CUDA Debugging Tutorial : Controlling Execution : Viewing GPU Threads : Viewing the Kernel’s Grid Identifier

TotalView supports showing the grid identification in the stack frame information when a CUDA thread stops, Figure 271.

Figure 271, Viewing the Grid and Parent Grid Identifiers

The grid is a unique identifier for a kernel running on a device. CUDA supports kernels launching parallel kernels on the same device. The parent grid is the identifier of the grid that launched the kernel currently in focus.
