Hi,

Is there an international number for the bridge? I cannot get to either
of the numbers mentioned below.

Best regards.

all,

I scheduled a telecon to discuss status and get somewhat organized 
for the meeting:

Thursday April 24, 10:00 MDT
local number:      606-1201(6-1201)
toll free number:  888 343-0702.

I'll send out some slides for the 5 minute briefing for the group.

I'm having a hard time finding time to devote to this, but I'll have 
a cut at the OpenMPI and LAMPI analysis prior to the telecon.  We 
need someone to look at MPICH, and the vendor implementations need to 
be posted.

Jeff
