Video: A Brief Introduction to OpenFabrics

Sean Hefty from Intel presented this talk at the Intel HPC Developer Conference at SC15. “OpenFabrics Interfaces (OFI) is a framework focused on exporting fabric communication services to applications. OFI is best described as a collection of libraries and applications used to export fabric services. The key components of OFI are: application interfaces, provider libraries, kernel services, daemons, and test applications. Libfabric is a core component of OFI. It is the library that defines and exports the user-space API of OFI, and is typically the only software that applications deal with directly. It works in conjunction with provider libraries, which are often integrated directly into libfabric.”

Call for Participation: 2016 Open Fabrics Workshop

The 2016 OpenFabrics Workshop has issued its Call for Participation. The event takes place April 4-8, 2016 in Monterey, California. The Workshop is the premier event for collaboration between OpenFabrics Software (OFS) producers and those whose systems and applications depend on the technology. Every year, the workshop generates lively exchanges among Alliance members, developers and users who all share a vested interest in high performance networks.

Video: NVM Express Introduction and Tutorial

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.

Slidecast: New IBTA Volume 1 Specification Release

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.”

Petaflop Radio Astronomy Signal Processing and the CASPER Collaboration

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.

Video: Shared Memory Communications Over RDMA (SMC-R) Update

“SMC-R is an open sockets over RDMA protocol that provides transparent exploitation of RDMA (for TCP based applications) while preserving key functions and qualities of service from the TCP/IP ecosystem that enterprise level servers/network depend on.”

Video: Exploring NFS/RDMA

In this video from the OpenFabrics International Developer Workshop 2014, Shirley Ma and Chuck Lever from Oracle present: Exploring NFS/RDMA.

OFA to Streamline Verbs Interface

“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.”
