Re: [HTCondor-users] USE_PSS=true not working for vanilla universe



Thanks for reply greg.

So basically ResidentSetSize reported already has PropotionalSetSize in it?

Thanks and regards

Hi Ram:

On the newer Ubuntu systems, HTCondor uses cgroup to measure memory of
jobs, and the default memory represents the physical memory pages used
by all processes in the job, and if two or more processes in a job share
a memory page, that page is only counted once. In this way, the
default memory reporting out of the box behaves more like the
proportional set size, which is not available on all Linux distributions.
