   limited to 4.
 - The number of multicast groups that an endpoint can support is limited to 2.
 
+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 which is the
+default.  See dump_pr.notes.txt in dump_pr for more information on both
+this  file  format and how to configure OpenSM to output this file.  By
+default, if the -p option  is  specified,  the  default  file  used  to
+preload these caches is ACM_CONF_DIR/ibacm_path_record.dump
