I am running Nsight Systems 2021.2.1 as admin on a Windows 10 system with a GV100, driver version 472.12.
The Nsight Systems documentation mentions an option for tracing GPU context switches:
- This can be set via the GUI, but it is mentioned only for Linux hosts. When will it also be available for Windows?
- This can be set as a command line parameter (–gpuctxsw). However, it seems not be supported, as nsys reports back: “unrecognised option ‘–gpuctxsw’”. Is this a bug or the flag is not supported via the command line either?
Any other way to profile GPU context switches on a Windows host machine?
