RCE 94: Libfabric

Brock Palen and Jeff Squyres speak with Sean Hefty about Libfabric a software implementation of Open Fabrics Interfaces (OFI). Libfabric is designed to minimize the impedance mismatch between applications, including middleware such as MPI, SHMEM, and PGAS, and fabric communication hardware. Its interfaces target high-bandwidth, low-latency NICs, with a goal to scale to tens of thousands of nodes.
