Hi Ralph,
It seems as if this issue is related to a missing shm_unlink wrapper
within Valgrind. I'm going to disable posix by default and commit
later today.
Thanks,

Hi Ralph,
That's mine - I'll take a look.
Thanks,

Whenever I run valgrind on orterun (or any OMPI tool), I get the
following
error msg:
--------------------------------------------------------------------------
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: Ralph
System call: shm_unlink(2)
Error: Function not implemented (errno 78)
--------------------------------------------------------------------------
It's coming out of open-rte/help-opal-shmem-posix.txt.
Everything continues, so I'm not sure what this is all about. Anyone
recognize this???
It's on the trunk, running on a Mac, vanilla configure.
Ralph
