Editing Sequent Computer Systems (section)

===NUMA===
Recognizing the increase in competition for SMP systems after having been early adopters of the architecture, and the increasing integration of SMP technology into microprocessors, Sequent sought its next source of differentiation. They began investing in the development of a system based on a cache-coherent non-uniform memory architecture ([[ccNUMA]]) and leveraging [[Scalable Coherent Interconnect]]. NUMA distributes memory among the processors, avoiding the [[wikt:bottleneck|bottleneck]] that occurs with a single monolithic memory. Using NUMA would allow their multiprocessor machines to generally outperform SMP systems, at least when the tasks can be executed close to their memory &mdash; as is the case for [[Server (computing)|server]]s, where tasks typically do not share large amounts of data.

In 1996 they released the first of a new series of machines based on this new architecture. Known internally as STiNG, an [[abbreviation]] for ''Sequent: The Next Generation (with Intel inside)'', it was productized as NUMA-Q<ref name=NUMA.q>{{cite web | url=https://www.computerworld.co.nz/article/518203/auckland_university_first_buy_sequent_numa-q_box | archive-url=https://web.archive.org/web/20190623084303/https://www.computerworld.co.nz/article/518203/auckland_university_first_buy_sequent_numa-q_box | archive-date=2019-06-23 | title=IT news, careers, business technology, reviews }}</ref> and was the last of the systems released before the company was purchased by IBM for over $800 million.

IBM then started [[Project Monterey]] with [[Santa Cruz Operation]], intending to produce a NUMA-capable standardized [[Unix]] running on [[IA-32]], [[IA-64]] and [[IBM Power microprocessors|POWER]] and [[PowerPC]] platforms. This project later fell through as both IBM and SCO turned to the [[Linux]] market, but is the basis for "the new SCO"'s ''[[SCO v. IBM]]'' Linux lawsuit.
