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

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.
