[OMPI users] multipath support for infiniband

[Jens Domke]

Hello,

the InfiniBand architecture has a LMC feature to assign mutiple virtual 
LIDs to one port and so provides multiple paths between two ports. Is 
there a methode in openmpi to enable message-striping over these paths 
to increase bandwidth or avoid congestions?
(I don't mean the multirail feature, to split traffic across two ports 
of one Hca)
The only function I have found, was to enable automatic path migration 
over lmc, but this is only for failover, if I remember rightly.

Regards,
Jens
