Podcast: Slingshotting to Exascale

In this podcast, the Radio Free HPC team looks at the Cray Slingshot interconnect that will power all three of the first Exascale supercomputers in the US. “At the heart of this new interconnect is their innovative 64 port switch that provides a maximum of 200 Gb/s per port and can support Cray’s enhanced Ethernet along with standard Ethernet message passing. It also has advanced congestion control and quality of service modes that ensure that each job gets their right amount of bandwidth.”

Podcast: Reinventing the Memory-Storage Paradigm

In this Chip Chat podcast, Intel Fellow Frank Hady explores the relationship of memory and storage to compute, and outlines how Intel is helping accelerate performance throughout information ecosystems and re-invent the memory storage paradigm in systems. “Since its introduction, 3Dx Point memory, the basis for Intel Optane DC Persistent Memory, has helped mitigate one of the biggest bottlenecks to performance.”

Xilinx SmartNIC Accelerates Network, Storage, and Compute on Single Device

Today Xilinx announced the industry’s first SmartNIC platform delivering true convergence of network, storage and compute acceleration functions on a single device. “The U25 combines a highly optimized SmartNIC platform with a powerful and flexible FPGA-based engine that supports full programmability and turnkey accelerated applications. The U25 delivers a comprehensive SmartNIC platform to address the industry’s most challenging demands and workloads such as SDN, virtual switching, NFV, NVMe-oF, electronic trading, AI inference, video transcoding, and data analytics.”

Video: Ampere Altra is Industry’s First 80-Core Server Processor

Today Ampere announced that it has begun shipping the Ampere Altra processor, the industry’s first 80-core server CPU and the first cloud native CPU for modern cloud and edge computing data centers. Ampere Altra is the company’s next generation cloud-focused product, and first in a new class of CPUs rolling out on an annual basis from Ampere’s roadmap, that will provide predictable high performance, secure isolation through single-threaded cores, scalability across the entire platform, and new levels of power efficiency.

Mellanox to Acquire Titan IC for Security and Data Analytics

Today Mellanox announced that it has reached a definitive agreement to acquire privately held Titan IC, the leading developer of network intelligence (NI) and security technology to accelerate search and big data analytics across a broad range of applications in data centers worldwide. The acquisition will further strengthen Mellanox’s network intelligence capabilities delivered through the […]

GPCNeT or GPCNoT?

In this special guest feature, Gilad Shainer from Mellanox Technologies writes that the new GPCNeT benchmark is actually a measure of relative performance under load rather than a measure of absolute performance. “When it comes to evaluating high-performance computing systems or interconnects, there are much better benchmarks available for use. Moreover, the ability to benchmark real workloads is obviously a better approach for determining system or interconnect performance and capabilities. The drawbacks of GPCNeT benchmarks can be much more than its benefits.”

Supermicro announces Pole-mounted Ruggedized Servers for AI on the Edge

Today Supermicro announced first-to-market IP65 enclosure-based servers for 5G RAN, AI inferencing, and other edge-focused applications based on Intel Xeon D and 2nd Gen Intel Xeon processors and broad configuration options. “Based on Supermicro’s Building Block Solutions, these 5G systems can be configured with a variety of processor and memory combinations so that customers can tailor their solutions to push data center remote management to the Edge. Supermicro has extensive experience with popular virtualization and container software such as Kubernetes, to efficiently facilitate these interactions, and has multiple servers certified NGC-Ready for Edge to extend AI capabilities across public and private networks.”

Advanced Clustering now offering Intel Cascade Lake Refresh Processors

Today Advanced Clustering Technologies announced that the company is now integrating Intel’s new Cascade Lake Refresh (CLX-R) processor into its line of HPC ACTblade and ACTserv clusters and ACTstation workstations. “Pricing for the new servers amounts to a 60% reduction in per-core pricing. According to Intel, Cascade Lake Refresh offers an average of 36% more performance than the previous generation.”

Arista Acquires Big Switch Networks

Arista Networks has completed its acquisition of Big Switch Networks, a network monitoring and Software Defined Networking pioneer. “Arista Networks provides a complete and visionary cloud networking suite, with rich capabilities in all critical areas of the campus, data center and public cloud. The acquisition of Big Switch will further strengthen the company’s network monitoring and observability suite delivered through Arista’s software platform CloudVision and DANZ (Data ANalyZer) capabilities.”

Full-spectrum HPC Scheduling

Our friends over at Altair explain how a meta-scheduler, or hierarchical scheduler, can be thought of as a private or team-based scheduler that uses shared underlying resources. Difficult workloads and special workloads are good candidates for meta-scheduling. Examples include sets of several hundred thousand short jobs, jobs with complex dependencies, and workflows that are continually introspected for status.
