Ralph, thanks. I'll try it on Tuseday.
Let me confirm one thing. I don't put "-with-libevent" when I build
openmpi.
Is there any possibility to build with external libevent automatically?

Not entirely sure - add "-mca rmaps_base_verbose 10 --display-map" to your cmd
line and let's see if it finishes the mapping.
Unless you specifically built with an external libevent (which I doubt), there
is no conflict. The connection issue is unlikely to be a factor here as it
works when not
Thank you, Ralph.
Then, this problem should depend on our environment.
But, at least, inversion problem is not the cause because
node05 has normal hier order.
I can not connect to our cluster now. Tuesday, going
back to my office, I'll send you further report.
Before that, please let me know y
Dear Open MPI users,
in my institution a cluster with dual-rail IB has recently deployed. Each
compute node has two physical single-port Mellanox Connect-IB MT27600 card
(mlx5_0, mlx5_1). By running bandwidth tests (OSU 4.2 benchmark) using
MVAPICH2, I can achieve from one node to another (1 MP
It seems to be working fine for me:
