[Lustre-discuss] Lustre over Pathscale''s Infinipath HCA
Can I compile lustre to use Pathscale''s infinipath drivers. Right now I dont see lustre supporting Pathscale''s IB driver. So can I somehow make lustre to use IB HCA using Pathscale''s native IB drivers. -- Regards-- Rishi Pathak -------------- next part -------------- An HTML attachment was scrubbed...

We don''t have a lustre network driver specifically for Pathscale.
However Pathscale support OFED, and we do have a driver for that
- the o2iblnd.
Cheers,
Eric

We already have 16 infinipath HCA''s installed.But can''t use OFED as pathscale''s mpi , pathcc and pathf90 will not work with other IB drivers and we paid a lot of money for these.I tried IPoIB but still performance improvement is not much significatant.
