Dear Samuel,
Just as you replied I was trying that on the compute nodes. Surprise,
surprise...the value returned as the hard and soft limits is 1024.
Thanks for confirming my suspicions...

Hi,
It sounds like Open MPI is hitting your system's open file descriptor
limit. If that's the case, one potential workaround is to have your
system administrator raise file descriptor limits.
On a compute node, what does "ulimit -a" show (using bash)?
Hope that helps,

Dear OpenMPI developers,
One of our users was running a benchmark on a 1032 core simulation. He had a
successful run at 900 cores but when he stepped up to 1032 cores the job just
stalled and his logs contained many occurrences of the following line:
[d6copt368.crc.nd.edu][[25621,1],0][btl_tcp_
