bullx supercomputers

A range of servers specifically designed for HPC

Though the majority of supercomputers are clusters based on industry-standard components, there is no one-size-fits-all solution in extreme computing. Different applications require specific configurations and interconnect topologies. And each local environment has its own requirements in terms of footprint, power, and cooling. Beyond pure performance, supercomputing systems must not just leverage the latest technologies, but also perfectly meet the needs of every kind of application and user.

Bull’s R&D has designed the bullx family of servers to provide maximum flexibility in terms of interconnect, power, and cooling, and cover the widest possible spectrum of applications. Bull offers an infinitely adaptable response, with a large choice of compute nodes, accelerated nodes and specialized nodes. And of course this multitude of components can be combined, in a completely customized way, into a single bullx system and managed as a single system using the bullx supercomputer suite.
