The NVIDIA Nsight main menu has a global freeze option. This allows the user to control which warps will make progress when using any CUDA run control (such as stepping, resume, or run to cursor). For example, the user is able to ensure that only one warp moves when stepping.
Note that a barrier in the code will prevent a warp from making any progress, if the other warps are frozen. This is because all warps in a block need to get past the barrier, and they would not be able to if others are frozen. In this case, the user can use async break to get back control in the debugger. |
This option must be set in each debug session. It does not persist between sessions.
