In May, Intel announced the Many Integrated Core (MIC) architecture, with a development kit codenamed Knights Ferry. NVIDIA has announced and started to deliver its next-generation architecture, Fermi. PGI’s Michael Wolfe presents an in-depth comparison of the two designs.
At last week’s International Supercomputing Conference (ISC) in Hamburg, HPCwire sat down with Cray CTO Steve Scott to talk about life after Baker, where he revealed the company’s plans for its upcoming “Cascade” supercomputer and how the exascale landscape is shaping up.
Online, at conferences and in theory, manycore processors and the use of accelerators such as GPUs and FPGAs are being viewed as the next big revolution in high performance computing. If they can live up to the potential, these accelerators could someday transform how computational science is performed, providing much more computing power and energy efficiency.
The Roadrunner supercomputer at Los Alamos National Lab employed a hybrid Cell-Opteron architecture to be the first system to reach the petaflop milestone. But with the meteoric rise of more powerful general-purpose GPUs, the prospects for more Cell-based supercomputing may be dimming.
While hardware accelerators continue to show impressive performance results for supercomputing workloads, Intel is sticking to its CPU guns to deliver HPC to the broader market.
