Chipeta became available on 24 March 1998, supplementing paiute and ouray and increasing NCAR's computatonal capacity for the general user community by 50%. Named for the "Queen of the Utes" and devoted wife of Chief Ouray, the machine was virtually identical to Ouray. It had the same filesystem layout and system software, plus 24 processors, 1,024 megabytes of memory, and a sustained performance of 1.5 gigaflops sustained.

Like Ouray, Chipeta was good for large-memory jobs and was popular with users from the beginning. During the first week it was available to the community, it was filled to 99% capacity (partly, perhaps, because usage was free).

Chipeta was decommissioned on 3 September 2002. As technological trends continued to favor symmetric multiprocessor cluster systems built from relatively inexpensive commodity CPUs, the era of the high-performance vector-processor systems appeared to be ending.
