The Green HPCG List and the Road to Exascale

In this special guest post, Axel Huebl looks at the TOP500 and HPCG with an eye on power efficiency trends to watch on the road to Exascale. “This post will focus one efficiency, in terms of performance per Watt, simply because system power envelope is a major constrain for upcoming Exascale systems. With the great numbers from TOP500, we try to extend theoretical estimates from theoretical Flop/Ws of individual compute hardware to system scale.”

HPCG Benchmark offers a alternative way to rank Top Computers

“The LINPACK program used to represent a broad spectrum of the core computations that needed to be performed, but things have changed,” said Sandia researcher Mike Heroux, who created and developed the HPCG program. “The LINPACK program performs compute-rich algorithms on dense data structures to identify the theoretical maximum speed of a supercomputer. Today’s applications often use sparse data structures, and computations are leaner.”

Single Node “Cyclops” Supercomputer Looks to Set Records

Today the Radio Free HPC podcast team announced announced plans to build what they hope will be the “fastest single-node supercomputer in the world” for the High Performance Conjugate Gradients Benchmark (HPCG). “Codenamed “Project Cyclops”, the single-node supercomputer demonstrates the computational power that individual scientists, engineers, artificial intelligence practitioners, and data scientists can deploy in their offices.”

HPCG Performance List Released at SC16

“This is the sixth list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems. The first HPCG list was announced at ISC’14 two and a half years ago, containing 15 entries, the SC’15 list had 60 and ISC’16 had 80. The current list contains more than 100 entries as HPCG continues to gain traction in the HPC community.”

Deep Learning, Ocean Modeling, and HPCG Come to ASC16 Student Supercomputer Challenge

Today the ASC Student Supercomputer Challenge (ASC16) announced details from their Preliminary Contest on January 6. College students from around the world were asked to design a high performance computer system that optimizes HPCG and MASNUM_WAM applications under 3000W as well as to conduct a DNN performance optimization on a standalone hybrid CPU+MIC platform. All system designs along with the result and the code of the optimization application are to be submitted by March 2.

HPCG Benchmark Gains Traction for Ranking Supercomputers

The High Performance Conjugate Gradients (HPCG) benchmark continues to gain traction in the high-performance computing community. “HPCG is designed to complement the traditional High Performance Linpack (HPL) benchmark used as the official metric for ranking the top 500 systems,” said Sandia National Laboratories researcher Mike Heroux, who developed the HPCG program in collaboration with Jack Dongarra and Piotr Luszczek from the University of Tennessee.

New HPCG Benchmark List Goes Beyond LINPACK to Compare Supercomputers

The High Performance Conjugate Gradients (HPCG) Benchmark list was announced this week at SC15. This is the fourth list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems. The first HPCG list was announced at ISC’14 a year and a half ago, containing only 15 entries and the SC’14 list had 25. The current list contains more than 60 entries as HPCG continues to gain traction in the HPC community.

How to Measure a Supercomputer’s Speed?

In this special guest feature from Scientific Computing World, Adrian Giordani asks what benchmarks should be applied as the nature of supercomputing changes on the way to exascale.

Pleiades Supercomputer Moves Up the Ranks with Haswell

NASA reports that it’s newly upgraded Pleiades supercomputer ranks number 11 on the July 2015 TOP500 list of the most powerful supercomputers. And while the LINPACK computing power of Pleiades jumped nearly 21 percent, its ranking at number 5 on the new HPCG benchmark list reflects its ability to tackle real world applications.

Latest HPCG Performance List Complements TOP500

The latest High Performance Conjugate Gradients (HPCG) Benchmark list will be announced in a special session this week at ISC 2015. This is the third list produced for the emerging benchmark designed to complement the traditional High Performance Linpack (HPL) benchmark used as the official metric for ranking the Top 500 systems.
