[ewg] mvapich2 over iwarp DOA - bug520

[Steve Wise]

I just built and installed today's daily ofed-1.2 build and mvapich2
doesn't work at all over iwarp.   The build is
OFED-1.2-20070404-0600.tgz.

I've opened bug 520 to track this.

If I run a 2 node cpi, it hangs and never completes.

If I run a 2 node IMB-MPI1 I get a crash:

(gdb) bt

(gdb)

This is mvapich2-0.9.8-9.  I believe I tested a development build of
this code directly from OSU before they shipped it in OFED-1.2.  I don't
know yet what's up.

dapltest and rping work across my cluster so I think this is an mvpich2
issue.

Shaun/Sundeep:  Have you all tested the ofed-1.2 build with 0.9.8-9 yet?
