The five E Models of the FACOM VP Series (FACOM VP-30E, VP-50E, VP-100E,VP-200E and VP-400E) were announced in July 1987 as enhanced versions of Fujitsu's FACOM VP-100 Series of supercomputers. These E models achieve performance 1.5 times that of the previous FACOM VP-100 Series machines by adding high-speed vector memory and adding an arithmetic pipeline. This Series was the first in the world equipped with virtual computer capability, and this enabled use even in the UNIX environment.

(Note) The above specifications are from the time of announcement, and may have been changed due to later improvement.
*1: By adding the VSU to the main memory, the max. 256MB real memory area could be expanded up to a maximum of 1GB (that was amount of main memory capacity and VSU capacity) in vector processing.
