Following Jeff's suggestion adding devel mailing list. Hi All, I am currently facing strange situation that I can't run OMPI on more than 65 nodes. It seems like environmental issue that does not allow me to open more connections. Any ideas ? Log attached, more info below in the mail.

What environment are you running in (rsh, slurm, ??)? If you configured --enable-debug, then please run it with --mca plm_base_verbose 5 --debug-daemons and send the output On Aug 11, 2014, at 12:07 AM, Lenny Verkhovsky <len...@mellanox.com<mailto:len...@mellanox.com>> wrote: I don't think so, It's always the 66th node, even if I swap between 65th and 66th I also get the same error when setting np=66, while having only 65 hosts in hostfile (I am using only tcp btl ) Lenny Verkhovsky SW Engineer, Mellanox Technologies www.mellanox.com<http://www.mellanox.com/> Office: +972 74 712 9244 Mobile: +972 54 554 0233 Fax: +972 72 257 9400 From: users [mailto:users-boun...@open-mpi.org] On Behalf Of Ralph Castain Sent: Monday, August 11, 2014 1:07 AM To: Open MPI Users Subject: Re: [OMPI users] OpenMPI fails with np > 65 Looks to me like your 65th host is missing the dstore library - is it possible you don't have your paths set correctly on all hosts in your hostfile?

It looks like MPI failes to open 66th connection even with running `hostname` over tcp. It also seems to unrelated to specific host.
