Introduction
The prototypes described in this section are the Arm-based systems available to the Mont-Blanc partners and end-users to test our software and scientific applications on state-of-the-art Arm architectures.
Mont-Blanc 3 prototype: Dibona
As part of the Phase 3 of Mont-Blanc, Atos built a new prototype. It is named Dibona, after the Dibona peak in the French Alps, and it started operation in Fall 2017. It is based on 64 bit ThunderX2 processors from Marvell®, relying on the Arm® v8 instruction set.
The prototype leverages the BullSequana X1000 infrastructure, including ultra efficient Direct Liquid Cooling – cooling with warm water.
The full configuration includes:
- 48 bi-socket computes nodes
- ie. 96 Marvell® ThunderX2 CPUs (32 cores)
- or 3072 cores
- 12288 threads
The system also features the Mont-Blanc optimized software stack, and an InfiniBand EDR interconnect.
Three compute nodes are integrated side by side in each BullSequana blade.
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 BullSequana X1000 range.
First commercial Arm-based HPC system announced worldwide
