Myrinet already supports multiple cards, even on multiple PCI busses
where they exist. However, it doesn't automagically use the cards in a
useful fashion. That would require either some minor hacking
(modifying mpirun, for example, to have certain neighbors use certain
cards) or moderate hacking to the internals of gm (transparent
multiplexing).
