Bull Sequana X1000 supercomputers

Paving the way towards Exascale challenges

Open supercomputers

Open for future technologies. Bull Sequana X1000 proposes a large choice of processors (Intel CPUs, accelerators, ARM processors…) and different interconnect technologies (BXI, InfiniBand…), thus offering maximum investment protection. It is designed to integrate the most advanced technologies, ready to support the future technologies that will make it possible to reach the exaflops level.
Limit energy consumption. Controlling energy consumption is the main roadblock on the path to exascale. Bull Sequana X1000 is ultra energy-efficient: it targets a PUE very close to 1. 100% of the components of sequana – both compute nodes and switches – are cooled with warm water up to 40°C, using an enhanced version of the Bull Direct Liquid Cooling (DLC) technology.
Accelerate application performance. Exascale application performance requires massive parallelism. Bull Sequana features the Bull Exascale Interconnect (BXI) developed by Atos specifically for exascale. BXI introduces a revolution with a hardware acceleration technology that frees up processors from all communication tasks.

Bull Sequana X1000 cell

Bull Sequana X1000 compute cabinet

There are two types of compute cabinets:
The base compute cabinet provides liquid cooling to the compute blades it houses and also to the switch cabinet.
The extension compute cabinet is optional and has its own cooling sub-system.

Three types of interfaces connect the compute and switch cabinets together:
Liquid interface with two flexible pipes from Base compute cabinet hydraulic chassis to switch cabinet manifolds.
Interconnect interface: each node is connected through one or two interconnect links, one per NIC.
Management interface for all management controllers in the compute cabinet (PMC, BMC, HMC): one 1Gb/s Ethernet link per node plus 4 sidebands signals for platform management.

The compute nodes are connected to the switch cabinet (L1 switches) via 12 copper cable octopuses named:
Sideplane Octopus Double for 2 NICs per node,
Sideplane Octopus Single for 1 NIC per node.

Each Bull sequana X1000 compute cabinet houses 48 horizontal compute blades, with the associated power modules at the top of the cabinet and the redundant hydraulic modules for cooling at the bottom of the cabinet.

24 blades are mounted on the front side of the cabinet, while the 24 other blades are mounted on the rear side.
Each 1U blade contains three compute nodes, except for GPU-based blades which contain one node.

Each cell can therefore contain up to:
288 dual-socket Intel® Xeon® nodes OR,
288 single-socket Intel® Xeon Phi™ nodes OR,
96 dual-socket Intel® Xeon® nodes with 4 Nvidia® Pascal GPUs.

Bull Sequana X1000 cell

Bull Sequana switch cabinet

The central Bull Sequana X1000 switch cabinet houses:

two levels of interconnect switches in full fat-tree topology,
their associated DC power generator (SWPG: SWitch Power Group) and
management components such as Ethernet switches and one redundant server for Island management and administration (ISMA).

The switch cabinet provides internal connections (within the cell) through copper cables and external connections through optical cables.

288 external ports are available to interconnect each cell with the rest of the system to form different topologies, such as Fat-tree, All-to-all or other directly connected configurations.

External nodes (such as for example input/ output gateways, services nodes…) can be plugged into the L1 switches replacing compute nodes.
