Do you need an operating system specifically designed to run demanding HPC applications? HPE Cray Operating System is a suite of high-performance software designed to run large, complex applications at scale. Based on standard SUSE Enterprise Linux, the software provides many features designed to improve application efficiency, reliability, management, and extend data access. Features Maximize your HPE Cray Supercomputing Operating System Software What's New Support for HPE Cray XD systems with HPE Slingshot interconnect Improving Workload Performance HPE Cray OS features CPU assignment which constrains OS operations to specific Linux hardware threads eliminating noise from the remaining CPUs so that applications have dedicated CPUs for a better workload performance. Additional Huge Page sizes we added deliver less latency by avoiding address translation cache misses in limited-sized network address translation hardware - important for applications with large memory footprints and sparse reference patterns. XPMEM – enables enhanced memory sharing between processes to increase on-node MPI performance. The software controls turbo boost to provide predictable, consistent performance of the system. Going Beyond Standard Linux Capabilities HPE Cray OS offers fine-grained monitoring of power usage of the running applications so users can decide whether they want to contain or exploit available power resources and make sure their system runs efficiently. Advanced Kernel Debugging extends the crash capabilities of the community Linux kernel debugger supporting diskless nodes and huge pages for large scale systems.
