In this video from the 2015 OFS Developer’s Workshop, Parav Pandit from Emulex presents: Workload Driven Memory Registration.
NVM Express is a specification for accessing solid-state drives (SSDs) attached through the PCI Express (PCIe) bus. “NVM” stands as an acronym for non-volatile memory, which is used in SSDs. As a logical device interface, NVM Express has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and mirroring the parallelism of contemporary CPUs, platforms and applications. By allowing parallelism levels offered by SSDs to be fully utilized by host’s hardware and software, NVM Express brings various performance improvements.
In this slidecast, Bill Lee and Rupert Dance from the InfiniBand Trade Association describe the new IBTA Volume 1 Specification Release. “The new release defines new capabilities that will enable computer systems to keep up with the requirements for increased scalability and bandwidth, along with high computing efficiency and high availability for both high performance computing and commercial enterprise data centers.”
In this video from the OpenFabrics International Developer Workshop 2014, SETI@home co-founder Dan Werthimer presents: Petaflop Radio Astronomy Signal Processing and the CASPER Collaboration. As a bellwether for exascale, radio astronomy projects like CASPER and the SKA telescope are pushing the limits of high performance computing.
“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.”
“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.”
