RE: Memory/CPU Tweaking on Corra
Mi-Youn Brusniak
We mentioned Corra Installation guide section D.6 programs.xml about this
briefly.
you can also give the memory requirements (in bytes) for the programs (and
their modules).
More specifically, if you give the minimum memory acquirement or large
memory acquirement for <resources> tag of each module, it will automatically
set "vmem" option value of PBS and module will run on the nodes that meet
the minimum vmem value you set.

Subject: Memory/CPU Tweaking on Corra
Hi Mi-Youn,
Thanks again for your help from before. I have another question: I am
wondering if it is possible to tweak the amount of minimum memory (and
possibly also the number of CPU's + nodes) a particular program
allocates for the cluster job scheduler without having to recompile
the entire program? I tried to change the settings in the Corra/conf
directory while Corra is still running, and it doesn't seem to change
the amount of memory that the program requests from PBS.
(the main reason why I'm asking is because I'm running into the
problem of Maui determining that only three out of twelve CPU's are
"feasible" for a program to use while running a program that only uses
one CPU on one node.)
Thanks in advance,
Christian
