The CEES Grid is composed of two resource clusters, each with separate head nodes, separate compute nodes, separate Tool nodes, and a total of 3600 cores. They are located in different buildings, and do not share file systems. The Clusters can only be used by vested users; the Tool servers can be used by anyone in the Stanford School of Earth, Energy & Environmental Sciences.
