Now I was able to run MPI hello world example up to 3096 processes across
129 nodes (24 cores per node).
However, it seems to get stuck with 3097 processes.
Any suggestions for troubleshooting?

Hi,
Currently I'm having trouble to scale an MPI job beyond a certain limit.
So I'm running an MPI hello example to test beyond 1024 but it failed with
the following error with 2048 processes.
It worked fine with 1024 processes. I have enough file descriptor limit
(65536) defined for each process
