Tom,
i was able to reproduce the issue with an older v1.10 version, but not
with current v1.10 from git.
could you please give a try to 1.10.3rc1 available at
https://www.open-mpi.org/software/ompi/v1.10/downloads/openmpi-1.10.3rc1.tar.bz2
?
Cheers,
Gilles

Hello,
In this thread from the Open-MPI archives:
https://www.open-mpi.org/community/lists/devel/2014/03/14416.php
a strange problem with a system call is discussed, and claimed to be
solved. However, in running a simple test program with some new MPI-3
functions, the problem seems to be back: Here is an example message:
-------------------------------------------------------------------------------------
A system call failed during shared memory initialization that should
not have. It is likely that your MPI job will now either abort or
experience performance degradation.
Local host: cedar.reachone.com
System call: unlink(2)
/tmp/openmpi-sessions-rosmond@cedar_0/18624/1/shared_window_4.cedar
Error: No such file or directory (errno 2)
----------------------------------------------------------------------------------------
The same problem occurs on 2 different systems:
1. (Open MPI) 1.10.2 : gcc version 4.4.7 20120313 (Red Hat 4.4.7-16)
(GCC)
2. (Open MPI) 1.8.4 : gcc version 4.7.2 (Debian 4.7.2-5)
Attached are
1. ompi_info from the first system above
2. The source code of the test program (based on code downloaded from
an Intel source)
I simply do
mpicc shared_mpi.c
mpirun -np 8 a.out > outp
The program runs correctly on both system using Intel MPI, but returns
the messages above with Open MPI
