Chinook, an SGI Origin 3800 system, was made available to NCAR’s supercomputer users on July 15, 2002. The new machine was binary compatible with Ute, the Origin 2000 it replaced. It had the same number of processors but twice the clock speed, four times the memory, and more than double the disk capacity.

Chinook had 128 MIPS R14000 processors, a clock speed of 500 megahertz, 65 gigabytes of distributed shared memory, and 580 gigabytes of disk space. It was fitted with a HiPPI connection to NCAR's Mass Storage System and gigabit Ethernet to NCAR networks.

Also included in the Chinook complex was an 8-processor SGI Origin 2100 named Chinookfe, which functioned as a front end to Chinook for interactive work. Both Chinook and Chinookfe were decommissioned on August 31, 2004, as the Scientific Computing Division investigated newer compute servers with better price-performance.

The Chinook complex was allocated as part of the Climate Simulation Laboratory.
