Operating System
The different partitions of ASCI Red run on different Operating Systems. For example, users of the computer work in an environment called "Teraflops OS", an operating system (once called Paragon OS) that was originally developed for the Intel Paragon XP/S Supercomputer. ASCI Red's Compute partition runs on an operating system named Cougar. Cougar is a Sandia Labs and University of New Mexico collaboration; it is a lightweight OS based on PUMA and SUNMOS, two systems that were also designed for use on the Paragon supercomputer. It consists of a light weight kernel, the Process Control Thread, and other utilities and libraries. The Linux 2.4 kernel was ported to the system and a custom CNIC driver was written, but the heavy weight OS did not perform as well as the Cougar lightweight kernel on many benchmarks.

Famous quotes containing the words operating and/or system:
“Go on then in doing with your pen what in other times was done with the sword; shew that reformation is more practicable by operating on the mind than on the body of man.”
—Thomas Jefferson (17431826)
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a language acquisition device, an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
