Dear Ralph,
For the file descriptors the declared limit is over 65536 files but if
OMPI needs several of them, then this can be interesting. Is there any
source to read about it or I just should do trials? About the child
processes again, can I do something? I have root access, so I can change
Just glancing at the code, I don't see anything tied to 2**12 that pops out at
me. I suspect the issue is that you are hitting a system limit on the number of
child processes a process can spawn - this is different from the total number
of processes allowed on the node - or the number of file de
Dear Jeff,
Of course I was thinking to execute memtester on each node on the same
time and gather the outputs. However executing memtester on a node with
48GB memory it takes a lot of time (more than 1-2 hours, I don't
remember exactly, maybe even more because I cancelled its execution) and
I
Dear Ralph,
Thanks for the answer, I am using OMPI v1.4.1.
Best regards,
