IBM 3090

IBM 3090 was a high end IBM mainframe computer based on the System/370 architecture[1] , introduced in 1985. Models included the 150, 150E, 180, 200 (1985), 300 3-way (1987), 400 4-way (1985), 600E (1987), 600S (1988). The 400 and 600 were respectively 2 200s or 300s coupled together as one complex, and could run in either single-system image mode or partitioned into 2 systems.[2] The model 200 and model 400 were announced Feb 12, 1985 and withdrawn May 5, 1989.[3]
Vector facility
In October 1985, IBM introduced an optional vector facility for the IBM 3090; such a facility had not been previously available in the System/370 architecture, thus bringing integrated supercomputer capabilities to the mainframe line. IBM entered into partnerships with several universities to promote the use of the 3090 in scientific applications, and efforts were made to convert code traditionally run on Cray computers.[4] Along with the vector unit, IBM introduced their Engineering and Scientific Subroutines Library and a facility to run programs written for the discontinued 3838 array processor.[5]
