Thanks Jeff for the doc. However I'm not sure if I understand your
following comment correctly. If I remove the MX BTL plugins, a.k.a.,
mca_btl_mx.la and mca_btl_mx.so, I'm now getting errors of these
components not found.

[n0026.hbar:09467] mca: base: component_find: unable to open
.../mca_btl_mx.la: file not found (ignored)
[n0026.hbar:09467] mca: base: component_find: unable to open
.../mca_btl_mx.so: file not found (ignored)

And it still uses TCP BTL instead of MX MTL from what I can tell. Am I
doing things wrong?

Thanks,

Yong
