Using the --mca btl ^mx totally prevents use of mx interface. So
everybody uses tcp (even mx capable nodes). If you want a mixed
configuration you have to enforce use of the ob1 pml, but let the mx
btl be used where it is suitable (it will be disabled at runtime if it
can't run). You're pro
ey're expecting the mx library
to be there, but it's not?)

Hmm, that combination seems to hang on me - but
'--mca pml ob1 --mca btl ^mx' does indeed do the trick.
Many thanks!

Hi,
We have a mixed environment in which roughly 2/3 of the nodes
in our cluster have myrinet (mx 1.2.1), while the full cluster has
gigE. Running open-mpi exclusively on myrinet nodes or exclusively
on non-myrinet nodes is fine, but mixing the two nodes types
results in a runtime error (PML a
