[gpfsug-discuss] pagepool

[Jarsulic, Michael [BSD]]

Ibán,

What are you using for your scheduler?

On my compute nodes, I am setting the pagepool to 16 GB and setting aside specialized memory for GPFS that will not be allocated to jobs.

Good afternoon, We are new to the DSS system configurations. Reviewing the configuration I have seen that the default pagepool is set to this value: pagepool 323908133683 But not only in the DSS servers, but also in the rest of the HPC nodes

Good afternoon,
   We are new to the DSS system configurations. Reviewing the configuration I have seen that the default pagepool is set to this value:

    pagepool 323908133683

But not only in the DSS servers, but also in the rest of the HPC nodes and I don't know if it is an excessive value. We are noticing that some jobs are dying by "Memory cgroup out of memory: Killed process XXX", and my doubt is if this pagepool is reserving too much memory for the mmfs process in decripento of the execution of jobs.

Any advice is welcomed,

Regards, I
