Expand your horizons with hybrid Computing

Combining the resources and flexibility of different computing universes, Hybrid Computing enables organizations to take full advantage of both on-premises and cloud solutions to harness the full power of supercomputing,
for the widest possible spectrum of applications.
BullSequana XH2000 and its value added software ecosystem, businesses and organizations of all sizes and in all sectors will be able to run any type of workload, anywhere – now and tomorrow.

The critical role of the Atos XCS web portal for HPC & AI

With the democratization of High-Performance Computing (HPC) and the expansion of Artificial Intelligence (AI) in research and industries, organizations require more flexibility and more simplicity in the way they provide end-users with computing resources.
We are witnessing a progressive shift from a full-CAPEX (Capital Expenditure / investment) on-premises model to a more hybrid way of consuming computing power: through a mix of CAPEX and OPEX (Operational Expenditure / services).

BullSequana X supercomputers

Beyond pure performance, supercomputers must not just leverage the latest technologies, but also perfectly meet the needs of applications and users. Atos has designed the Bull ranges of HPC servers to provide maximum flexibility in terms of interconnect, processor type, power, and cooling, and cover the widest possible spectrum of applications. Bull supercomputers offer an infinitely adaptable response, from departmental HPC clusters to world-class supercomputers.
