[Paraview] peak memory use on remote nodes

[Biddiscombe, John A.]

Thanks Dave

A colleague here suggested I put my
aprun pvbatch <blah> into a script and add a ‘dtrace” command at the start of the script. This will then dump out a txt file on each node and after the job completes I can grep the info I need.

I’m going to give that a try first as it seems straightforward, but I will revert to your suggestion if I fail and nothing else comes up.

cheers

JB

Perhaps extend the benchmark to glean /proc/<PID>/status's VmHWM entry on Linux at least. Get the number for t1 and at t2 and subtract to see what the maximum was in between those two times.

Seems the right place to do that is kwsys/SystemInformation.cxx, but you could prototype in the script.
Hope that helps and please post some code. Seems like a very useful thing to have.

The python scripting module “paraview.benchmark” allows one to get the memory use using “paraview.benchmark.get_memuse” - but I presume this is the memory reported as used by the system at the moment when the function is called.

Does anyone know a way of recording the peak memory use on remote nodes between t1 and t2 - where t1 and t2 are the start and stop of either a function, job or even paraview python script on the remote node?

thanks

JB
