Hello!
I am using Open MPI v1.8.1 and slurm 2.5.6.
I got this messages when i try to run example (hello_oshmem.cpp) program:
[warn] Epoll ADD(1) on fd 0 failed. Old events were 0; read change was 1 (add); write change was 0 (none): Operation not permitted
[warn] Epoll ADD(4) on fd 1 failed. Old events were 0; read change was 0 (none); write change was 1 (add): Operation not permitted
Hello, world, I am 0 of 2
Hello, world, I am 1 of 2
What does this warnings mean?
I lunch this job using sbatch and mpirun with hostfile (got it from :  $srun hostname -s|sort|uniq -c|awk '{print $2" slots="$1}' > $HOSTFILE)
Regards,
Timur
