System Configuration

Bridges comprises over 850 computational nodes, 

Bridges' computational nodes supply 1.3018 Pf/s and 274 TiB RAM.  The Bridges system also includes more than 6PB of node-local storage and 10PB of shared storage in the Pylon file system.

In addtion to its computational nodes, Bridges contains a number of login, database, web server and data transfer nodes.
