Paiute, a second J90 classic, was installed on 16 November 1995. This machine had 16 processors (each giving a sustained performance of about 60 megaflops), 256 megawords of central memory, 72 gigabytes of disk, and a clock period of 10 nanoseconds. Paiute had HIPPI connectivity to the Mass Storage System. It ran the UNICOS operating system and supports the Fortran 77, Fortran 90, C, and Fortran 90 compilers. It offered mathematical and statistical software and various vendor-supplied utilities.

Paiute was suitable for batch jobs that needed 10–128 megawords of memory, but not recommended for intensive interactive jobs because of insufficient job-swapping capabilities.

Paiute was decommissioned on 30 June 2000.
