TOP500 Expands Exaflops Capacity Amidst Low Turnover
Nov. 16, 2020

FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The 56th edition of the TOP500 saw the Japanese Fugaku supercomputer solidify its number one status in a list that reflects a flattening performance growth curve.  Although two new systems managed to make it into the top 10, the full list recorded the smallest number of new entries since the project began in 1993.

The entry level to the list moved up to 1.32 petaflops on the High Performance Linpack (HPL) benchmark, a small increase from 1.23 petaflops recorded in the June 2020 rankings. In a similar vein, the aggregate performance of all …

UCF Consortium Sees Strong Growth and Adoption of Multiple Open-Source Projects
Nov. 16, 2020

Modern HPC systems include extreme numbers of compute elements and extremely low-latency interconnection networks. In order to exploit the capabilities of these architectures and to meet their demands in scalability, communication software needs to scale and support applications with adequate functionality to express their parallelism. Moreover, communication software should add as little overhead as possible in order to avoid compromising the native performance of the interconnection network. These requirements make the design of high-performance communication software extremely intricate, since they demand minimal memory requirements and low instruction counts and cache activity while meeting stringent performance targets.

Submer: Highly Efficient, Sustainable Solutions for Datacenters that Make sense
Sept. 1, 2020

Datacenters can be considered as a sort of nervous system of the contemporary society. Just like the human nervous system, datacenters are not single structures, working on their own. Quite the contrary, “datacenters” are heterogeneous systems with multiple layers of complexity and integration and interaction, internally and externally. This apparently obvious statement should nevertheless be never forgotten because we are entering an era in which datacenters will play a fundamental role in our daily lives. And to make the next digital revolution (in fact, already undergoing), sustainable, we as an industry must find …

Japan Captures TOP500 Crown with Arm-Powered Supercomputer
June 22, 2020

FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The 55th edition of the TOP500 saw some significant additions to the list, spearheaded by a new number one system from Japan. The latest rankings also reflect a steady growth in aggregate performance and power efficiency.

Minimize Supercomputing Data Center Downtime and Increase Security with NVIDIA Mellanox UFM Cyber-AI
June 22, 2020

Data centers host many users and applications and have become the competitive advantage for research organization and manufacturing companies. Keeping the data center intact and healthy is critical, as operational costs of supercomputers continue to rise, driven by growing scientific computing demands and new security threats. Moreover, malicious users may exploit data center access to misuse compute resources by running prohibited applications, such as crypto currency mining, resulting in unexpected downtimes and higher operating costs. This week, NVIDIA unveiled the Unified Fabric Manager (UFM) Cyber-AI platform, which minimizes downtime and saves OPEX in InfiniBand data centers by harnessing AI-powered  analytics …

Call from participation in the 55th TOP00 / GREEN500 lists
April 9, 2020

The TOP500 authors encourage the HPC community to submit entries for the 55th TOP500 and Green500 lists. The June 2020 TOP500 list is released during the ISC High Performance conference, which will be held in digital form from June 22-24 due to the COVID-19 pandemic this year. The submission and publication schedule of the June list is NOT affected by this change.
