Multiple operating systems on one processor complex
by T. L. Borden, J. P. Hennessy, J. W. Rymarczyk
As large computing systems continue to grow in capacity and to offer improved price/performance, there is an increasing requirement to consolidate systems onto one processor complex. This paper describes the reasons why users need to run multiple operating systems today, provides a brief history of IBMs partitioning products, and introduces the Processor Resource/Systems Manager, a machine feature on the IBM 3090 Model E and ES/3090 Model S processors that provides users with a flexible and efficient capability to run multiple operating systems on a single processor complex.
