lnet infiniband config
...art of sles11 kernel 2.6.27 +
Lustre 1.8.3 + ofed 1.4.2 right, because it allows me to see and use the

A. I''ve got many more clients than servers in my cluster. I don''t
care if an individual client can''t get 2 rails of bandwidth because
the servers are the actual bottleneck...
