Hi Daniel --
PSM should determine your node setup and enable shared contexts
accordingly, but it looks like something isn't working right. You
can apply the patch I've attached to this e-mail and things should
work again.
However, it would be useful to identify what's going wrong. C
The words 'eager', 'rendezvous' or 'credit' have a specific resonance
only for implementors and i think it's correct that the MPI
specification sidestep these words since they are artifacts of
implementation.
All implementations make their own guarantees and run into their own
different limitation

By using non-blocking communications, you choose to expose separate
initiation and synchronization MPI calls such that an MPI
implementation is free to schedule the communication in any way it
wants between these two points (while retaining MPI semantics). At
your advantage, this may mea
How about a hostfile such as

1 node0
2 node0
3 node1
4 node0
5 node1
6 node1
Looks like the function to express the mapping is not anything simple. If it's
an expressible function but too complicated for open mpi, you'll have to make

PSM depends on InfiniPath 2.0, to be released in early November. We
are currently packaging psm.h as part of the infinipath-devel rpm.
