Clustrx is a new HPC OS designed for supercomputers of any size, including those with accelerators. It features a real-time monitoring and control system integrated into the OS. Clustrx is intended to efficiently share supercomputing resources across heterogeneous architectures. It aims to provide infinite scalability for education and allow service providers to offer extended billing models.

What’s Clustrx?
• OS for supercomputers, not only for nodes
• Integral solution, it’s the OS for infrastructure’s
elements as well as for computing nodes
• Designed for supercomputers of any size,
including heterogenous systems with extensive
accelerators’ usage
