1.0rc6 is now available; we made some minor fixes in gm, the datatype engine, and the shared memory btl. I'm not sure if your MX problem will be fixed, but please give it a whirl. Let us know exactly which version of MX you are using, too.

Thanks!

I can't believe I missed that, sorry.  :-(

None of the btl's are capable of doing loopback communication except
"self."  Hence, you really can't run "--mca btl foo" if your app ever
sends to itself -- you really need to run "--mca btl foo,self" at a
minimum.

This is not so much an optimization as it is a software engineering
decision; we didn't have to include the special send-to-self case in
any of the other btl components this way (i.e., less code, less complex
maintenance).

One other thing I noticed...  You specify -mca btl openib.  Try
specifying -mca btl openib,self.  The self component is used for
"send to self" operations.  This could be the cause of your failures.
