HPE Cray Operating System
SLES-derived node OS and management stack for Cray EX.
Why this part
The Cray Linux Environment's successor after HPE's acquisition, rebuilt around containerised system services and a SLES base rather than a custom distribution. It is now the single most widely deployed operating system in this dataset by installed FLOPS: Frontier, El Capitan, Aurora, LUMI, Alps, Perlmutter, Venado, Isambard-AI and Shaheen III all run it, which is the software-layer counterpart to Slingshot's dominance of the fabric layer. The same acquisition put both under one supplier.
