OFA to Streamline Verbs Interface

Bill D'Amico

“OpenFabrics Alliance members are working to streamline and make the verbs interface more efficient. Since this is an open source effort this will take some time, but the consensus is that there is too much overhead both in the depth of the call stack and in the size of associated data structures for verbs to scale well in the exascale era.”

Jim Ryan Recaps the OpenFabrics Workshop 2014

Jim Ryan, OFA Chair

Over at the OpenFabrics Blog, OFA Chairman Jim Ryan writes that the recent OpenFabrics Workshop reflected a year of work identifying and engaging with interest groups.

OpenFabrics Interfaces Working Group Architecture

“Verbs and RDMA-based networks will continue to be important focus areas, but with the new OFWG, the OFA is expanding its focus to include additional application-centric APIs that could be better suited to other areas and technologies,” said Jim Ryan, chairman, OFA. “Application-centric I/O is an extension of the approach historically taken by the OFA, and we will use our expertise in this area to guide the open source development of APIs and I/O libraries.”
