Servers and Workstations at the Computer Graphics Laboratory

A variety of UNIX-based servers and workstations provide the infrastructure for the compute- and data-intensive needs of our user community. The table below sumarizes these systems. (Not included in this table are our desktop computers.)

§ Host socrates is a cluster of symmetric multiprocessor (SMP) servers running Compaq's TruCluster Server software. Documentation on TCS is available here. Nodes on the cluster are interconnected using a high-bandwidth, low-latency interconnect technology known as Memory Channel, supporting 90MB/s channel bandwidth between any two server nodes and 2.1 usec end-to-end latency.
