Ultra Computer Services (UCS)


Cray XC series supercomputers are designed to handle the most challenging simulation, analytics and AI workloads with an architecture and software environment that provide extreme scalability and sustained performance. Seamless integration of Cray® ClusterStor™ storage into your overall system configuration provides enhanced data management and faster time to discovery.

  • The Cray® XC50™ supercomputer supports the newest generation of CPU and GPU processors — Cavium ThunderX2 processors, NVIDIA® Tesla® P100 PCIe GPUs and Intel® Xeon® Scalable processors — coupled with the Aries™ network and Cray’s HPC-optimized software stack including the Cray Linux® Environment and Cray Programing Environment, to deliver our fastest system with peak system performance of 500 PF and 1 PF in a single cabinet.
  • The Cray® XC50-AC™ air-cooled supercomputer, supporting NVIDIA Tesla P100 PCIe GPUs, Intel Xeon Scalable processors and ARM-based processors, delivers up to 236 TF peak performance in a 24” cabinet with no requirement for liquid cooling or extra blower cabinets. Ideal for dedicated test, development, AI and analytics use cases, the air-cooled XC50 system offers all of the benefits of our XC50 supercomputer in a smaller form factor.
  • The Cray® XC40™ system offers the combined advantages of the Aries interconnect and Dragonfly network topology, Intel Xeon multi-core and Intel® Xeon Phi™ many-core processors, delivering up to 100 PF sustained system performance. It’s designed for production supercomputing and user productivity.


We take a comprehensive approach to our XC series software environment, delivering an optimized suite of Linux®-based OS, management, monitoring and development tools which provide scalable performance and reliability for challenging HPC workloads. The environment efficiently supports the application development life cycle by providing a tightly coupled software stack. Multiple programming languages, programming models, compilers, I/O libraries, optimized scientific libraries, and tools for debugging, performance analysis, workload management, environment setup and more are supported.
