Tempest, the SGI Origin 3800

On October 4, 2004, the SGI data analysis and processing platform dataproc was decommissioned and replaced by a greatly enlarged SGI platform called tempest. The primary purpose of tempest is interactive data processing and analysis.

Tempest has 128 500-MHz R14000 processors, 64 gigabytes of distributed shared memory, and 4.2 terabytes of disk space. It is connected to the Mass Storage System by fibre channel and to NCAR networks by gigabit Ethernet.
