*Nodes = User-available nodes. For total nodes, see our higher-level overview "Livermore Computing Systems Summary."

**Total memory = for most systems, this number is the total CPU node-only memory; for Sierra, Lassen (coming soon) , and RZAnsel, this is CPU+GPU.

Access: Platforms are General Availability unless "access" is marked as "Limited."

System Status

Operating Systems

OS (operating system) types are TOSS 3/TOSS (Tri-Lab Operating System Stack—formerly CHAOS, Clustered High Availability Operating System—derived from Red Hat Linux); SLES/CNK (SuSE Linux Enterprise Server/Compute Node Kernel); and RHEL (Red Hat Enterprise Linux). Click on platform name to see OS information for each platform.
