@HPCpodcast: Views and Insights on the New TOP500 List

The big news on the Monday of each annual Supercomputing Conference is the release of the new TOP500 ranking of the world’s most powerful supercomputers. At this years SC23 here in Denver, the big news is that the  top 10 of this year’s list has more changes than any list in recent memory….

Aurora Exascale Install Update: Cautious Optimism

The twice-annual TOP500 list of the world’s most powerful supercomputers is not universally loved, arguments persist whether the LINPACK benchmark is an optimal way to assess HPC system performance. But few would argue it serves a valuable purpose: for those installing leadership-class supercomputers, the TOP500 poses a challenge and a looming deadline that “concentrates the mind wonderfully.”

@HPCpodcast: Paul Messina and the Journey to Exascale

From the early days of supercomputing through the success of exascale supercomputing, few HPC luminaries have played as important and integral leadership role in HPC as Dr. Paul Messina. So as we observe Exascale Day today, we are delighted to discuss the exascale journey with someone instrumental to the 10 orders of magnitude of improvement in ….

AMD MI300 Accelerators Expected to Bring Choice to GPU Market

[Sponsored Guest Article]  If you agree that generative AI signifies a new chapter in IT, then you may also agree there’s a major storm gathering among GPU accelerator chip vendors vying for position in the GenAI market. It’s a competition with the potential to roil not only the microprocessor sector….

Building a Capable Computing Ecosystem for Exascale

With ECP, working together was a prerequisite for participation. “From the beginning, the teams had this so-called ‘shared fate,’” says Siegel. When incorporating new capabilities, applications teams had to consider relevant software tools developed by others that could help meet their performance targets, and if they didn’t choose to use them….

At the HPC User Forum: 2 Full Days in Tucson of HPC and AI

This week saw HPC industry analyst firm Hyperion Research host the HPC User Forum, a supercomputing conference with an end-user emphasis held four times a year (two in the U.S. and two internationally) offering two intensive days of presentations and panels involving commercial and government users, along with hardware and software vendors.
