Tom, For your first question: yes, an HCA port can belong to multiple partitions. Trivial example: All HCAs must always be able to communicate with the SM, so they must be members of the SM's partition even if they are also members of (for example) the "MPI Traffic" partition.

Can an HCA port belong to more than 1 partition at a time? How do you configure partitions with opensm? From reading the opensmd man page, it looks like you just create a file called /etc/osm-partitions.conf, with port GUIDs and such, but is this current? I ask because according to the man page the opensm configuration file is in /etc/opensm/ . Can you tell opensm where to look for the partitions file?
