A Tightening Exascale Race Reveals Underlying Forces Shaping Supercomputing

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.

European Program to Develop Supercomputing Chips Begins to Take Shape

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.

Benchmarks in Hand, UK Academics See Promising Future for Arm Chips in HPC

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.

Cloud Computing in HPC Surges

According to the two leading analyst firms covering the high performance computing market, the use of the cloud for HPC workloads is looking a lot more attractive to users these days.

New GPU-Accelerated Supercomputers Change the Balance of Power on the TOP500

For the first time in history, most of the flops added to the TOP500 list came from GPUs instead of CPUs. Is this the shape of things to come?
