+# This is the default system-wide MCA parameters defaults file.
+# Specifically, the MCA parameter "mca_param_files" defaults to a

+# (this file is the latter of the two).  So if the default value of

+# 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

+# the default value decisions are effectively distributed.  Hence,
+# these values are only applicable on nodes that "see" this file.  If

+# to this file will need to be propagated to other nodes.  If $sysconf
