Tackling Power and Resilience at Exascale

Jul 21, 2015 |

Although the utility of FLOPS-driven benchmarks can make for interesting debate, the fact remains that major supercomputing milestones, like 1,000X performance advances, are integral to scientific discovery and also serve to drive interest and investment in the HPC ecosystem at large. The boon of accelerators helped propel HPC past the petascale marker in 2008, but fielding an Read more…

IDC: The Changing Face of HPC

Jul 16, 2015 |

At IDC’s annual ISC breakfast there was a good deal more than market update numbers although there were plenty of those: “We try to track every server sold, every quarter, worldwide,” said Earl Joseph, IDC program vice president and executive director HPC User Forum. Perhaps more revealing and as important this year was IDC’s unveiling Read more…
