Solution for nvidia-smi problems

Accelerated Computing CUDA CUDA on Windows Subsystem for Linux

nvidia-smi is working from windows
1- you can always call it from windows cmd [DOS Shell]
or power shell or terminal actually it is in Windows/System32
i.e it is in path
2- for whatever reason you like to call from wsl2 here:

/mnt/c/Windows/System32/nvidia-smi.exe

ok.
try it yourself

2

look to
/mnt/c/Windows/System32/nvidia-smi.exe --help
or what you think about
/mnt/c/Windows/System32/nvidia-smi.exe -l

3

/mnt/c/Windows/System32/nvidia-smi.exe -l
is the poorman profiler
it takes a snapshoot every second untill you break it with ctrl+c
you can make it even better by using
-lms, --loop-ms= Probe until Ctrl+C at specified millisecond interval.

for example
–loop-ms= 100
it takes a a snapshoot every 100 milliseconds i.e 10 snapshoot per seconds

BUT USE
/mnt/c/Windows/System32/nvidia-smi.exe --loop-ms= 100 >> result.txt

of course it is better to call it dirctly from command prompt/powershell inside windows
then you can “clean” it using your favourite editor. mine is"ultraedit" using macros
you can make “nicer”

why we need profiler : to monitor GPU usage and memory state
in the windows taskbar it is not accurate to show up your apps
activiity.

i shall back with some examples to compare wsl vs. windows
