The competition between the US, China, and Japan to field the first exascale supercomputer looks a lot closer than it did a couple of years ago. But the real significance of the narrowing schedules reflects a shift in technology preferences and a trend toward domestic control of HPC hardware.
The European Processor Initiative (EPI), an ambitious program to develop a pair of chips for domestic supercomputers, is poised to change the way Europe does HPC. And although the work is still very much in its early stages, it looks like the Europeans have selected their preferred processor architectures: Arm and RISC-V.
Researchers at the Great Western 4 (GW4) Alliance have benchmarked the Cavium ThunderX2 processor that will soon power the Isambard supercomputer. But the most significant advantage of the Arm processor may have nothing to do with performance numbers.
The International Supercomputing Conference (ISC18) kicked off Monday in Frankfurt, Germany, with Maria Girone, CTO of CERN openlab delivering the opening keynote address. She explained how CERN’s needs will drive exascale computation and data science innovation in the future.
The TOP500 list is an intensely valuable tool for the HPC community, tracking aggregate trends over 25 years. However, a few observers have noted that recent publications of the TOP500 list have many duplicate entries, often at anonymous sites.
FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The TOP500 celebrates its 25th anniversary with a major shakeup at the top of the list. For the first time since November 2012, the US claims the most powerful supercomputer in the world, leading a significant turnover in which four of the five top systems were either new or substantially upgraded.
On Wednesday evening at the ISC High Performance conference, HPC luminary Dr. Thomas Sterling will deliver his customary keynote address on the state of high performance computing. To get something of a preview of that talk, we caught up with Sterling and asked him about some of the more pressing topics in the space.
Sandia National Laboratories will soon be taking delivery of the world’s most powerful supercomputer using ARM processors. The system, known as Astra, is being built by Hewlett Packard Enterprise (HPE) and will deliver 2.3 petaflops of peak performance when it’s installed later this year.
