The ILLIAC IV was the first massively parallel computer. The system was originally designed to have 256 64-bit floating point units (FPUs) and four central processing units (CPUs) able to process 1 billion operations per second. Due to budget constraints, only a single "quadrant" with 64 FPUs and a single CPU was built. Since the FPUs all had to process the same instruction – ADD, SUB etc. – in modern terminology the design would be considered to be single instruction, multiple data, or SIMD.

rdfs:comment	El ILLIAC IV fue uno de los primeros supercomputadores de la historia. Uno de la serie de máquinas de investigación, los de la Universidad de Illinois, el diseño del ILLIAC IV se caracterizó por un nivel bastante alto de paralelismo con hasta 256 procesadores, solía permitir a la máquina trabajar en grandes conjuntos de datos en lo que más tarde se conocería como procesamiento vectorial. Después de varios retrasos y rediseños, la computadora fue entregada al Ames Research Center de la NASA, en las afueras de San Francisco, en 1971. Después de las pruebas y de 4 años de uso por parte de la NASA, el ILLIAC IV fue conectado a la para uso distribuido en noviembre de 1975, convirtiéndose en el primer supercomputador disponible en red, adelantándose al Cray-1 por casi 12 meses. (es) L'ILLIAC IV è uno dei più famosi supercomputer. Fu l'ultimo di una serie di computer di ricerca dell'University of Illinois. Il progetto dell'ILLIAC IV è un progetto basato su un parallelismo massivo con 256 processori, sviluppato per trattare grandi quantità di dati, un'idea che è alla base dei processori vettoriali. La macchina fu alla fine presentata nel 1976, dopo un decennio di sviluppo ed era molto in ritardo, molto costosa e con prestazioni molto inferiori a macchine come il Cray-1. (it) ILLIAC IV（イリアック・フォー）は、イリノイ大学アーバナ・シャンペーン校の一連の研究から生み出された最後のコンピュータである。パターソン＆ヘネシーは本機を「間違いなく、スーパーコンピューター・プロジェクトの歴史上で最も不名誉なものであろう。」としている。ILLIAC IV の設計の鍵は、256 プロセッサによる高い並列性で、後にSIMDと呼ばれる、同時に多数のデータセットを処理することを指向していた。マシンは十年の開発期間を経て1975年に完全に稼働した。 (ja) O ILLIAC IV foi um supercomputador construído pela a Universidade de Illinois e financiado pelo o governo dos Estados Unidos, sua construção custou 31 milhões de dólares. O projeto terminou em 1981. (pt) L'ILLIAC IV és un ordinador, considerat el primer de còmput paral·lel massiu. El sistema es va dissenyar inicialment amb 256 unitats de coma flotant (FPU) i quatre Unitats Centrals de Processament (CPUs) capaces de processar mil milions d'operacions per segon (1 GFLOP). Degut a problemes de pressupost, només van ser desenvolupats un únic "quadrant" amb 64 FPU i una sola CPU. Ja que totes les FPU havien de processar la mateixa instrucció en un moment donat - ADD, SUB etc. - En terminologia moderna, el disseny es consideraria de Single Instruction, Multiple Data, o SIMD.
