Compendium of articles published on Numerical Algorithms for HPC Science

The Royal Society Publishing has recently released a special compendium of articles based on a recent scientific discussion meeting with HPC Industry thought leaders. “This issue contains contributions from those who develop and implement numerical algorithms and software libraries – numerical analysts, computer scientists, and high-performance computing researchers – with those who use them in some of today’s most challenging applications.”

Interview: Exascale Computing Project Update for 2020

In this video, Exascale Computing Project Director Doug Kothe describes how disciplined and tailored project management led to very impressive results in what was likely the most comprehensive independent review of the project to date. “ECP’s products will be robust, production ready, and functional right out of the box; and ECP is driving the sharing of information through regular training not only with ECP participants but also the broader US high-performance computing community to lower barriers to using exascale systems and accelerated architectures in general.”

Podcast: Earth and Space Science for Exascale

In this podcast, Anshu Dubey of Argonne National Laboratory describes the Earth and Space Science application portfolio in the Exascale Computing Project (ECP). “By and large, these applications are solving partial differential equations, and so there is that generality,” Dubey said. “Most times, the range of scales is so huge that you cannot resolve every scale, so then you have to do something called subgrid models, which can be very boutique.”

ECP Report: Advancing Scientific Productivity through Better Scientific Software

The Exascale Computing Project has published a new report to foster and advance software productivity and sustainability for extreme-scale computational science. The report introduces work by the IDEAS-ECP project, explaining its approach, outcomes, and impact of work in partnership with the ECP and broader computational science community. The DOE Exascale Computing Project (ECP) provides a […]

Argonne to Deploy Cray ClusterStor E1000 Storage System for Exascale

Today HPE announced that ALCF will deploy the new Cray ClusterStor E1000 as its parallel storage solution. The new collaboration supports ALCF’s scientific research in areas such as earthquake seismic activity, aerospace turbulence and shock-waves, physical genomics and more. “Our recent introduction of the Cray ClusterStor E1000 is delivering ALCF unmatched scalability and performance to meet next-generation HPC storage needs to support emerging, data-intensive workloads.”

Podcast: Supercomputing the Human Microbiome

In this Let’s Talk Exascale podcast, Kathy Yelick and Lenny Oliker from LBNL describe how the ExaBiome project is developing computational tools to analyze microbial species—bacteria or viruses that typically live in communities of hundreds of different species. “Pushing past the traditional shared-memory-system approach, the ExaBiome team has developed efficient distributed memory implementations and analyzed some of the largest datasets in the metagenomics community.”

Podcast: A Codebase for Deep Learning Supercomputers to Fight Cancer

In this Let’s Talk Exascale podcast, Gina Tourassi from ORNL describes how the CANDLE project is setting the stage to fight cancer with the power of Exascale computing. “Basically, as we are leveraging supercomputing and artificial intelligence to accelerate cancer research, we are also seeing how we can drive the next generation of supercomputing.”

Registration Opens for HPC User Forum in Princeton, NJ

Hyperion Research has posted their preliminary agenda for the upcoming HPC User Forum. The event takes place March 30 – April 1 in Princeton, New Jersey. “The HPC User Forum was established in 1999 to promote the health of the global HPC industry and address issues of common concern to users ( The organization has grown to 150 members.”

Podcast: Will the ExaSky Project be First to Reach Exascale?

In this Lets Talk Exascale podcast, Katrin Heitmann from Argonne describes how the ExaSky project may be one of the first applications to reach exascale levels of performance. “Our current challenge problem is designed to run across the full machine [on both Aurora and Frontier], and doing so on a new machine is always difficult,” Heitmann said. “We know from experience, having been first users in the past on Roadrunner, Mira, Titan, and Summit; and each of them had unique hurdles when the machine hit the floor.”

Podcast: Software Deployment and Continuous Integration for Exascale

In this Let’s Talk Exascale podcast,  Ryan Adamson from Oak Ridge National Laboratory describes how his role at the Exascale Computing Project revolves around software deployment and continuous integration at DOE facilities. “Each of the scientific applications that we have depends on libraries and underlying vendor software,” Adamson said. “So managing dependencies and versions of all of these different components can be a nightmare.”
