Does the OpenIB BTL have the notion of include and exclude of HCA's as
the TCP BTL does for NICs? E.G. "--mca btl_tcp_if_include eth1,eth2 ..."
I think not but I was not sure if this was accomplished some other way
so wanted to ask the group.

Glenn,
If the error message is about "privileged" memory, i.e. locked or
pinned memory, on Solaris you can increase the amount of available
privileged memory by editing the /etc/project file on the nodes.
Amount available (example of typical value is 900MB):
% prctl -n project.max-device-locked-
Glenn,
With CT7 there is a utility which can be used to clean up left over
cruft from stale MPI processes.
% man -M /opt/SUNWhpc/man -s 1 orte-clean
Achtung: This will remove current running jobs as well. Use of "-v" for
verbose recommended.
I would be curious if this helps.

Couple of things.
With linux I believe you need the interface instance in the 7th field of
the /etc/dat.conf file.
example:
InfiniHost0 u1.1 nonthreadsafe default /usr/lib64/libdapl.so ri.1.1 " " " "
should be
InfiniHost0 u1.1 nonthreadsafe default /usr/lib64/libdapl.so ri.1.1 "ib0 0 " " "
Also, you will want to check that you have valid entries in
/etc/dat.conf. You might see the message you report if this is empty.

Hi,
I can only speak to Sun's use of uDAPL as it relates to MPI.
From what I can tell Sun is the only group interested in the uDAPL BTL
in Open MPI at this point. In contrast, Open MPI has many active members
interested in the development of the OpenIB BTL which uses the user
verbs protocol.
Yes I understand what you are doing but there is still a possible error
case I was trying to consider and your initial placement of the call
outside of the af==AF_INET check lead me to assume you were using
something other than IPv4 which is why I was asking if you had an

You are right Prism will not work with Open MPI which Sun's ClusterTools
