SGI

The Trusted Leader in High Performance Computing

 

Congratulations NASA - Pleiades Now Ranks as World's 5th Most Powerful Supercomputer in the HPCG Benchmark

August 20, 2015

One of our recent blogs discussed how SGI has moved up in the latest TOP500 List which was announced at ISC in Frankfurt this July. In addition, the blog detailed how SGI scored a 30% increase in delivered systems from last November's TOP500 released at SC14 (Supercomputing 2014).

Another big topic at ISC was the HPCG (High Performance Conjugate Gradients) Benchmark project, which is an effort to create a more relevant metric for ranking HPC systems than the High Performance LINPACK (HPL) benchmark. This companion metric is designed to exercise computational and data access patterns that more closely match a broad set of important applications, and to motivate computer system designers to invest in capabilities that will have impact on the collective performance of these applications.

We are proud to congratulate our partner NASA for making its debut on the HPCG benchmarking list, where its Pleiades supercomputer ranked fifth in the world. Pleiades is based on SGI® ICE™ X racks containing the latest generation of Intel® Xeon® E5-2680 v3 processors. Upgrades include 4,176 12-additional core Haswell processors, each performing twice as many scientific calculations per second as the previous generation of Intel processors. According to a recent NASA Blog, this architecture achieves sustained performance on the HPCG benchmark of 131.90 teraflops (trillion floating-point operations per second).

Supercomputing is crucial to NASA for enabling breakthroughs across numerous mission-related fields of study. We look forward to continuing to help NASA advance their high performance computing systems, providing faster access to key insights that improve the agency's ability to successfully achieve mission goals.
