They are the running metrics. While the task is running, they will tell you how
much pmem/vmem it is using at that point of time. Obviously at the end of job,
it will be the last snapshot.

Thanks for the response. So they represent the total physical memory
(virtual memory) has been allocated to the job (e.g., from heap and stack)
during its entire life time? I am still confused how to get the cumulative
number from /proc/meminfo. I think from /proc/meminfo we can only get the
As Vinod Kumar Vavilapalli they are indeed snapshots in point and time. So
they are neither the peak usage from the whole duration of the job, nor
cumulative aggregate that increases over time.

No, every so often, 3 seconds IIRC, it capture pmem and vmem which corresponds
to the usage of the process and its children at *that* specific point of time.
Cumulative = cumulative across the process and its children.

Hello,
I am wondering how memory counters 'PHYSICAL_MEMORY_BYTES' and
'VIRTUAL_MEMORY_BYTES' are calculated? They are peaks of memory usage or
cumulative usage?
Thanks for help,
