20 | # This is the default system-wide MCA parameters defaults file. |
---|
21 | # Specifically, the MCA parameter "mca_param_files" defaults to a |
---|
22 | # value of |
---|
23 | # "$HOME/.openmpi/mca-params.conf:$sysconf/openmpi-mca-params.conf" |
---|
24 | # (this file is the latter of the two). So if the default value of |
---|
25 | # mca_param_files is not changed, this file is used to set system-wide |
---|
26 | # MCA parameters. This file can therefore be used to set system-wide |
---|
27 | # default MCA parameters for all users. Of course, users can override |
---|
28 | # these values if they want, but this file is an excellent location |
---|
29 | # for setting system-specific MCA parameters for those users who don't |
---|
30 | # know / care enough to investigate the proper values for them. |
---|
31 | |
---|
32 | # Note that this file is only applicable where it is visible (in a |
---|
33 | # filesystem sense). Specifically, MPI processes each read this file |
---|
34 | # during their startup to determine what default values for MCA |
---|
35 | # parameters should be used. mpirun does not bundle up the values in |
---|
36 | # this file from the node where it was run and send them to all nodes; |
---|
37 | # the default value decisions are effectively distributed. Hence, |
---|
38 | # these values are only applicable on nodes that "see" this file. If |
---|
39 | # $sysconf is a directory on a local disk, it is likely that changes |
---|
40 | # to this file will need to be propagated to other nodes. If $sysconf |
---|
41 | # is a directory that is shared via a networked filesystem, changes to |
---|
42 | # this file will be visible to all nodes that share this $sysconf. |
---|
43 | |
---|
44 | # The format is straightforward: one per line, mca_param_name = |
---|
45 | # rvalue. Quoting is ignored (so if you use quotes or escape |
---|
46 | # characters, they'll be included as part of the value). For example: |
---|
47 | |
---|
48 | # Disable run-time MPI parameter checking |
---|
49 | # mpi_param_check = 0 |
---|
50 | |
---|
51 | # Note that the value "~/" will be expanded to the current user's home |
---|
52 | # directory. For example: |
---|
53 | |
---|
54 | # Change component loading path |
---|
55 | # component_path = /usr/local/lib/openmpi:~/my_openmpi_components |
---|
56 | |
---|
57 | # See "ompi_info --param all all" for a full listing of Open MPI MCA |
---|
58 | # parameters available and their default values. |
