it.

Hi Howard,

Yes, I have a script file that I call with the Open MPI version that I want
to build so that I can't forget to use an empty directory, to remove the
last installation before installin
/usr/bin/ofed_info
So, the OFED on your system is not MellanoxOFED 2.4.x but smth else.
try #rpm -qi libibverbs

Hi Jack,
Are you using a system at LANL? Maybe I could try to reproduce the problem
on the system you are using. The system call stuff adds a certain bit of
zest to the problem. does the app make fortran system calls to do the
copying and pasting?

Can you send your full Fortran test program?

I am using a “homecooked” cluster at LANL, ~500 cores. There are a whole bunch
of fortran system calls doing the copying and pasting. The full code is
attached here, a bunch of if-then statements for user options. Thanks for the
help.

Hi all
I am install mpi (version 1.6.5) at ubuntu 14.04. I am teach parallel
programming in undergraduate course.
I wnat use rsh instead ssh (default).
I change the file "openmpi-mca-params.conf" and put there
plm_rsh_agent = rsh .
The mpi application work, but a message appear for each pro
Use “orte_rsh_agent = rsh” instead

this is kind of a lanl thing. Jack and I are working offline. any
suggestions about openib and fork/exec may be useful however...and don't
say no to fork/exec not at least if you dream of mpi in the data center.

Disable the memory manager / don't use leave pinned. Then you can fork/exec
without fear (because only MPI will have registered memory -- it'll never leave
user buffers registered after MPI communications finish).

I changed my downloaded MOFED version to match the one installed on the
node and now the error goes away and it runs fine. But I still have a
question, I get the exact same performance on all the below 3 cases:
1) mpirun --allow-run-as-root --mca mtl mxm -mca mtl_mxm_np 0 -x
MXM_TLS=self,shm,rc,u
