HPC Network Stack on ARM

Pavel Shamis from ARM gave this talk at the MVAPICH User Group. “With the emerging availability HPC solutions based on ARM CPU architecture, it is important to understand how ARM integrates with the RDMA hardware and HPC network software stack. In this talk, we will overview ARM architecture and system software stack. We will discuss how ARM CPU interacts with network devices and accelerators. In addition, we will share our experience in enabling RDMA software stack and one-sided communication libraries (Open UCX, OpenSHMEM/SHMEM) on ARM and share preliminary evaluation results.”

OSC Hosts fifth MVAPICH Users Group

A broad array of system administrators, developers, researchers and students who share an interest in the MVAPICH open-source library for high performance computing will gather this week for the fifth meeting of the MVAPICH Users Group (MUG). “Dr. Panda’s library is a cornerstone for HPC machines around the world, including OSC’s systems and many of the Top 500,” said Dave Hudak, Ph.D., interim executive director of OSC. “We’ve gained a lot of insight and expertise from partnering with DK and his research group throughout the years.”

Video: iWARP Update from OpenFabrics Workshop

In this video from the OpenFabrics International Developer Workshop 2014, Brian Hausauer from Intel presents an iWARP Update. “The Internet Wide Area RDMA Protocol (iWARP) is a computer networking protocol for transferring data efficiently. It is sometimes referred to simply as “RDMA”, though RDMA is not a feature exclusive to iWARP.”
