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