[Lustre-discuss] Infiniband hot spot avoidance with LMC>0

[Nathan Dauchy]

Greetings,

Does Lustre's o2ib LND take advantage of Infiniband's LID Mask Count
(LMC) capability?  Might it be included in the future?  I'm looking for
something similar to the "MV2_USE_HSAM=1" option for Hot-Spot Avoidance
with MVAPICH2.

For anyone not familiar with LMC, see the "--lmc" option in the "opensm"
man page.

Thanks,
Nathan
