On 15 July 2002, a new SGI Origin 3800 system named chinook was made available for NCAR's users. The new machine was binary compatible with ute, the Origin 2000 it replaced, and 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.
The chinook complex was allocated as part of the Climate Simulation Laboratory (CSL).
Both chinook and chinookfe were decommissioned on 31 August 2004, as SCD investigated newer compute servers with better price-performance.
