This makes me happy. I've been playing with a standalone libfabric in my overlay via the sockets/UDP providers, and had nothing but problems when I tried to add USE flags for the various OFED bits (psm2 etc.) An up-to-date libfabric that pulls in ofed only when needed would finally enable people without the otherwise necessary fabric HW to write against the much more usable & sane (when compared to raw IB verbs) libfabric APIs. As far as the name is concerned IMHO fabric sounds less RDMA-specific; I think the OFI WG now also prefers implementation-neutral terms. cheers, Holger
