> 2. adjust the SYSTEM_PERIODIC_HOLD expression. Perhaps it should look at ResidentSetSize instead of ImageSize? (ResidentSetSize is available in Condor 7.6.) Unfortunately, that is not perfect. A job might be able to cause thrashing but not have a strikingly huge resident set size. It also may over-count memory that is shared between processes in the job. In Condor 7.7.0, there will be a new job attribute ProportionalSetSizeKb, which measures PSS as reported by Linux. This is like ImageSize (i.e. VSIZE), but it has the advantage of not over-counting memory that is shared between the multiple processes in a job.
Thanks Dan, this seems to have solved that for me for now. I'll look forward to ProportionalSetSizeKb when that comes out.
> Unfortunately, the Memory attribute of the machine is in megabytes. The ImageSize attribute in the job is in kilobytes. Confusing!
Thanks for the clarification, I see the suffix on: ProportionalSetSizeKb !
Thanks again, Dan
