Re: [OMPI users] Shared Libraries

Also, I recommend you do not name your library libmpi.so, since this name is already used by Open MPI Cheers, Gilles On Saturday, June 25, 2016, Jeff Squyres (jsquyres) wrote: > On Jun 24, 2016, at 4:39 PM, Richard C. Wagner > wrote: > > > >

Ralph and Jeff: Thanks for your replies to my questions about compiling a 32-bit MPI library for Forth. Ralph wrote: IIRC, you would need to write a wrapper to let Forth access C-based functions, yes? You could configure and build OMPI as a 32-bit library, and libmpi.so is C, so that isn?t

Ok, great. I've opened up https://github.com/open-mpi/ompi/pull/1814 to track the issue. This hack around certainly isn't going to ship in an Open MPI production tarball; we should probably do something more formal / correct. > On Jun 24, 2016, at 10:31 AM, kna...@gmail.com wrote: > > Jeff,

Jeff, It works now! Thank you so much! [user@ct110 hello]$ /opt/openmpi/1.10.3-1/bin/mpirun --mca btl self,tcp --mca btl_tcp_if_include venet0:0 --mca oob_tcp_if_include venet0:0 -npernode 1 -np 2 --hostfile mpi_hosts.txt hostname ct110 ct111 [user@ct110 hello]$

[OMPI users] tcp_peer_send_blocking: send() to socket 9 failed: Broken pipe (32) on openvz containers

Hi all! I am trying to build a cluster for MPI jobs using OpenVZ containers (https://openvz.org/Main_Page). I've been successfully using openvz+openmpi during many years but can't make it work with OpenMPI 1.10.x. So I have a server with openvz support enabled. The output of it's ifconfig:
