HPE Cray Operating System
Do you need an operating system specifically designed to run demanding HPC applications?
HPE Cray Operating System (OS) is a suite of high-performance software designed to run large, complex applications and scale efficiently to more than 500,000 processor cores with hardened low-jitter OS at its core. This custom OS does not alter the ability to run standard Linux® applications, but rather enhance it for performance, scale, and reliability. The suite also offers integrated container support so you can accommodate a wider variety of workloads, making your systems ready for the exascale era.
Infrastructure Software for the Exascale Era
HPE Cray OS is based on SUSE® Linux Enterprise Server (SLES) with enhancements for high performance computing.
We crated a compute image that is particularly small in footprint, helping to maximize available computing resources and has a low-jitter OS to remove performance thieves.
The enhancements do not alter the ability to run standard Linux applications, but rather enhance it for performance, scale, and reliability.
The software suite offers integrated container support for more flexibility and many ISV applications are available “out of the box”.
Integrated Performance, Resiliency, and Health Features
HPE Cray OS includes RAS features such as services to verify compute nodes run efficiently with integrated performance testing and hardware reporting.
Integrated node health service means that users can validate compute nodes prior to application launch to help maximize use of available resources.
HPE Cray OS offers power and frequency limiting for power capping and management.
Integrated support for Lustre® parallel file systems and enhanced compute node file system projection.
Leverage Cray Supercomputing Lineage
HPE Cray Operating System was developed and enhanced over several decades to address specific needs of HPC customers.
Built with features for the new era of computing, based on a long history of supercomputer leadership.
HPE Cray OS is fully supported by HPE Pointnext Services.
