No need for it to be in the base (we mistakenly thought it was used in multiple shmem components). This commit was SVN r25662. The following SVN revision numbers were found above: r25652 --> open-mpi/ompi@7e223b5799

[sys call fail]
|
|
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.

[mmap on nfs]
|
|
WARNING: Open MPI will create a shared memory backing file in a
|
|
directory that appears to be mounted on a network filesystem.
|
|
Creating the shared memory backup file on a network file system, such
|
|
as NFS or Lustre is not recommended -- it may cause excessive network
|
|
traffic to your file servers and/or cause shared memory traffic in
|
|
Open MPI to be much slower than expected.
|
|
|
|
You may want to check what the typical temporary directory is on your
|
|
node. Possible sources of the location of this temporary directory
|
|
include the $TEMPDIR, $TEMP, and $TMP environment variables.
|
|
|
|
Note, too, that system administrators can set a list of filesystems
|
|
where Open MPI is disallowed from creating temporary files by setting
|
|
the MCA parameter "orte_no_session_dir".
|
|
|
|
Local host: %s
|
|
Fileame: %s
|
|
|
|
You can set the MCA paramter shmem_mmap_enable_nfs_warning to 0 to
|
|
disable this message.
