*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."
