TSRI Computer and Network Facilities

The Institute maintains central computing resources which include two 64-bit LINUX clusters, garibaldi and bluefish, and a large shared memory SGI Linux machine (yellowtail). The garibaldi LINUX cluster has a total of 3020 CPUs available for computations, while the bluefish LINUX cluster contains 576 processors. The SGI LINUX machine, yellowtail, is a 128 CPU SGI 3700 server, with 128 GBytes of memory and one Terabyte of local disk space. Between local and shared disks each of these clusters has over fifty Terabytes of disk space available for computational data. These systems use the Portable Batch System (PBS) batch queueing system to ensure maximum system throughput and fair access

An extensive data communications network connects 19 buildings on campus. The major computer and data servers are connected via Gigabit Ethernet switches and routers. The majority of workstations, personal computers, and smaller computer servers utilize Fast Ethernet (100Mbps) and Gigabit Ethernet (1000Mbps) connections to the network.

This network links together over 5500 computers. Approximately 600 of these are high-end Unix based graphics workstations and servers, largely represented by Linux/Intel. Other Unix workstations include SGI and SUN workstations, and increasingly, Apple Mac Pro. The other computers are divided between Windows and Macintosh desktop computers.

The Institute operates a central data archival facility which uses a Silicon Graphics Altix 350 server, a thirty five Terabyte disk cache, and a large high speed StorageTek tape library. Current capacity is approximately 2500 Terabytes.

The Institute operates a central backup facility which provides periodic full backups and daily incremental backups of computer systems. The system uses a number of servers and two tape libraries housed in two buildings to provide disaster recovery.

Various groups within the Institute maintain hardcopy output devices which include a Solitaire film recorder and numerous color and B/W laser printers.

Off campus resources such as massively parallel computers at various Supercomputer Centers are accessible via a full duplex 100 Megabit fast ethernet Internet connection.
