[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.

[target full]
|
|
It appears as if there is not enough space for %s (the shared-memory backing
|
|
file). It is likely that your MPI job will now either abort or experience
|
|
performance degradation.
