Hi,

http://open-mx.org give a pretty good summary of the current status of
Open-MX. The stack is plugged on top of the Ethernet layer in the Linux
kernel to send/receive MX messages. The MX firmware is basically
emulated in a kernel module without requiring any specific feature in
the hardware.

Release 0.3 is young but I am confident that it's not too bad. The
performance still needs improvement but the stack is already reasonably
stable. At least MPICH-MX and Open MPI build on top of it and complete
IMB. I encourage people to test it and send some feedback.

If you need more information, feel free to ask.

Brice
