HPC Breaks Through to the Cloud: Why It Matters

In this special guest feature, Scot Schultz from Mellanox writes researchers are benefitting in a big way from HPC in the Cloud. “HPC has many different advantages depending on the specific use case, but one aspect that these implementations have in common is their use of RDMA-based fabrics to improve compute performance and reduce latency.”

The State of High-Performance Fabrics: A Chat with the OpenFabrics Alliance

In this special guest feature, Paul Grun and Doug Ledford from the OpenFabrics Alliance describe the industry trends in the fabrics space, its state of affairs and emerging applications. “Originally, ‘high-performance fabrics’ were associated with large, exotic HPC machines. But in the modern world, these fabrics, which are based on technologies designed to improve application efficiency, performance, and scalability, are becoming more and more common in the commercial sphere because of the increasing demands being placed on commercial systems.”

Designing HPC, Big Data, & Deep Learning Middleware for Exascale

DK Panda from Ohio State University presented this talk at the HPC Advisory Council Spain Conference. “This talk will focus on challenges in designing HPC, Big Data, and Deep Learning middleware for Exascale systems with millions of processors and accelerators. For the HPC domain, we will discuss about the challenges in designing runtime environments for MPI+X (PGAS OpenSHMEM/UPC/CAF/UPC++, OpenMP, and CUDA) programming models. Features and sample performance numbers from MVAPICH2 libraries will be presented.”

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.”

RoCE Initiative Launches Online Product Directory

Today the RoCE Initiative at the InfiniBand Trade Association announced the availability of the RoCE Product Directory. The new online resource is intended to inform CIOs and enterprise data center architects about their options for deploying RDMA over Converged Ethernet (RoCE) technology within their Ethernet infrastructure.

Experiences with NVMe over Fabrics

“Using RDMA, NVMe over Fabrics (NVMe-oF) provides the high BW and low-latency characteristics of NVMe to remote devices. Moreover, these performance traits are delivered with negligible CPU overhead as the bulk of the data transfer is conducted by RDMA. In this session, we present an overview of NVMe-oF and its implementation in Linux. We point out the main design choices and evaluate NVMe-oF performance for both Infiniband and RoCE fabrics.”

OFA Workshop in Austin to Put Spotlight on InfiniBand and RoCE

“The OpenFabrics Alliance (OFA) workshop is an annual event devoted to advancing the state of the art in networking. The workshop is known for showcasing a broad range of topics all related to network technology and deployment through an interactive, community-driven event. The comprehensive event includes a rich program made up of more than 50 sessions covering a variety of critical networking topics, which range from current deployments of RDMA to new and advanced network technologies.”

Designing HPC & Deep Learning Middleware for Exascale Systems

DK Panda from Ohio State University presented this deck at the 2017 HPC Advisory Council Stanford Conference. “This talk will focus on challenges in designing runtime environments for exascale systems with millions of processors and accelerators to support various programming models. We will focus on MPI, PGAS (OpenSHMEM, CAF, UPC and UPC++) and Hybrid MPI+PGAS programming models by taking into account support for multi-core, high-performance networks, accelerators (GPGPUs and Intel MIC), virtualization technologies (KVM, Docker, and Singularity), and energy-awareness. Features and sample performance numbers from the MVAPICH2 libraries will be presented.”

Mellanox 25G/100G Ethernet Speeds Speech Recognition at iFLYTEK

Today Mellanox announced that one of China’s leading intelligent speech and language technologies’ companies, iFLYTEK, has chosen Mellanox’s end-to-end 25G and 100G Ethernet solutions based on ConnectX adapters and Spectrum switches for their next generation machine learning center. The partnership between Mellanox and iFLYTEK will enable iFLYTEK to achieve a high speech recognition rate of 97 percent.
