We're going a bit OT for the hwloc list, but that still sounds weird to me. Doesn't Lustre use libibverbs? libibverbs is the C API interface to iWARP/IB. ...or is Lustre using IPoIB? (in which case nothing is using "native" iWARP/IB API access) -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
