Each node is directly connected to four others using crossed Category-5 stranded cable to form a hypercube network. The hypercube is augmented with two 3Com SuperStack II Switch 3000 TX 8-port Fast Ethernet switches, which also provide connectivity to the front-end. Uniterruptible power is provided by an APC Smart-UPS 2200.
For Supercomputing '96, each node has an added D-Link DFE-500TX 100 Mb Fast Ethernet Adapter, which provides connectivity to the Caltech machine.
Each node is running Linux. We use the standard Linux software tools and the GNU programming tools. The kernel has not been modified from its form in the Linux distribution.Back to Loki Home Page
