As part of the Phase 3 of Mont-Blanc, a new prototype is built by Atos. It is named Dibona, after the Dibona peak in the French Alps, and it will start operation in Fall 2017. It is based on 64 bit ThunderX2 processors from Cavium®, relying on the ARM® v8 instruction set.
The prototype leverages the Bull Sequana X1000 infrastructure, including Direct Liquid Cooling – cooling with warm water. Three compute nodes will be integrated side by side in each Bull Sequana X1000 blade.
The full configuration will ultimately include 48 computes nodes, ie. 96 Cavium® ThunderX2 CPUs, or 3000 cores.
Atos announced at ISC 2017 that the blade model developped for the Mont-Blanc prototype would be productized commercialized by Atos as part of its Bull Sequana X1000 range.
