AMD EPYC CPUs Deliberate For European Climate-Predicting Supercomputer

AMD not too long ago bought one other contract with the Archer 2 Supercomputer in Edinburgh for his or her EPYC CPUs. This contract is with Atos, who’re constructing a weather-predicting supercomputer, the BullSequana XH2000. This weather-prediction machine is deliberate to be out there for greater than 30 nations and runs a high-resolution climate prediction with a spread of as much as 10 km.

AMD bought the contract with Atos to construct the European Centre for Medium-Vary Climate Forecasts.

This supercomputer is deliberate to be put in for the European Centre for Medium-Vary Climate Forecasts (ECMWF) analysis middle. The middle will make the most of this supercomputer in a 24/7 operational climate service in Bologna, Italy.

Atos already has a number of XH2000 supercomputers, however particularly, this one can be constructed on the high-end AMD EPYC 7742 CPUs which function 64-cores and 128-threads with a TDP of 225W. This AMD EPYC CPU has a 1.four GHz base clock and a lift clock of two.2 GHz and is constructed round AMD’s 7 nm course of node.

Supply: Atos

Every XH2000 42U cupboards will have the ability to home as much as 32 compute blades, these blades make the most of liquid-cooling and are housed in a 1U compute blades. These blades can accommodate as much as three compute nodes that may provide help for AMD’s EPYC chips, Intel’s Xeon, and Nvidia’s Volta V100. This extensive organize of compatibility permits these cupboards / compute blades to be configured exactly to the consumer’s wishes. The XH2000 42U cupboard has an influence distribution unit that makes use of a type issue of two.5U, and this additionally displays the ability circuit with an influence administration controller module.

“This new answer will optimize ECMWF’s present workflow to allow it to ship vastly improved numerical climate predictions,” Sophie Proust, Atos Group CTO, mentioned in a press release. “Most significantly, although, this can be a long-term collaboration, one by which we’ll work carefully with ECMWF to discover new applied sciences to be ready for next-generation purposes.” The constructing of those methods is deliberate to begin this yr (2020), with service planning to begin in 2021. The meeting of the XH2000 set up in Bologna. This service can be accessible to researchers from greater than 30 nations, and the longterm objective is having the ability to run higher-resolution climate predictions of 10 km.
