+The ibacm contains several internal caches. These include caches for
+GID and LID destination addresses. These caches can be optionally
+preloaded. ibacm supports the OpenSM dump_pr plugin "full" PathRecord
+format which is used to preload these caches. The file format is specified
+in the ibacm_opts.cfg file via the path_rec_fmt parameter which should
+be set to full_opensm_v1 for this file format. Default format is
+none which does not preload these caches. See dump_pr.notes.txt in dump_pr
