'''IRIX''' ({{IPAc-en|ˈ|ai|ɹ|ɪ|k|s}}, {{respell|EYE|ricks}}) is a discontinued [[operating system]] developed by [[Silicon Graphics]] (SGI) to run on the company's proprietary [[MIPS architecture|MIPS]] workstations and servers. It is based on [[UNIX System V]] with [[Berkeley Software Distribution|BSD]] extensions. In IRIX, SGI originated the [[XFS]] file system and the industry-standard [[OpenGL]] [[graphics API]].
