Computer Facilities

Our cluster consists of a file server and over 800 P4 cores distributed in 5 sub clusters: B (32 cores), C (8 cores), D (16 cores), E (384 cores), and F (384 cores). We use T100/T1000 networks for system management and T1000/IB networks for interprocessor communication. Each B, C, and D cluster has its own gigabit switch, while the E cluster is switched by a stacked array of 4 X 48 port switches. The latest F nodes use a QDR Infiniband switching fabric.
