400 GbE and HPC

John D’Ambrosia

“The need for 400 GbE goes beyond its actual use in the development of systems for the TOP500.” As noted by the TOP500 itself, as justification for the list, “These people wish to know not only the number of systems installed, but also the location of the various supercomputers within the high performance computing community and the applications for which a computer system is being used. Such statistics can facilitate the establishment of collaborations, the exchange of data and software, and provide a better understanding of the high performance computer market.”

Windows RDMA File Storage

“Utilizing Mellanox’s RDMA-based interconnect solutions and Microsoft Windows Server 2012 R2, end-users can increase their application performance, improve their data center system efficiency, as well as consolidate their server and storage network infrastructure over a single-wire network for optimal CAPEX and OPEX savings.”

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.”

In this video from the OpenFabrics International Developer Workshop 2014, Paul Grun from OFA presents: Welcome, Introductions and Workshop Goals. “The 10th Annual OpenFabrics International Developer Workshop held on March 30-April 2 offered a multi-day event dedicated to the development and improvement of OpenFabrics Software (OFS). The Workshop kicked off Sunday, March 30, with a keynote from Dr. Thomas Sterling, Executive Associate Director and Chief Scientist at CREST. Presentations began the following morning covering topics focused on I/O for Exascale systems and Enterprise applications and included interest areas such as distributed computing, storage and data access and data analysis applications.”

Supercomputing: A Ground-Based Instrument for Exploration

Bob Ciotti

“Named after the astronomical open star cluster of the same name, Pleiades, one of the world’s most powerful supercomputers, represents NASA’s state-of-the-art technology for meeting the agency’s supercomputing requirements, enabling NASA scientists and engineers to conduct modeling and simulation for NASA missions.”

Over at Google Plus, Jeff Squyres has posted a somewhat belated April 1 post announcing an exciting new technology called the MPI over Everything Project (MPIoE). “One key innovative technology developed as part of the MPIoE effort is the Far Reaching Internet Datagram Efficiency (FRIDGE) framing protocol.”

HPCAC Swiss Conference Cluster Competition

In this video from the HPC Advisory Council Swiss Conference, HPC System Administrators compete in a Cluster Competition. “Administering a cluster with InfiniBand can be tricky. In this competition, contestants have just 10 minutes to answer a series of questions with only the command line at their disposal. It’s a battle; Who will win the iPad Air?”
