A Writeable Shared Segment Operating System (WSSOS) makes a VM Parallel Processing Environment (VMPE) more usable. WSSOS provides a unique and user-friendly parallel processing environment. A list of the major features offered by WSSOS is as follows: (Image Omitted) By itself, VMPE can execute one parallel job at a time. WSSOS allows several users to submit one or more parallel jobs to execute under VMPE at any one time. A job consists of parallel processes all sharing an area of writeable shared virtual memory. A dynamic process resource allocation scheme is provided by WSSOS through subroutine calls from an application program. These subroutines provide the "spawning" of a child process by a program call from its parent process.
