Chapter 1 Processes and Process Management In the MPE XL family of computer systems, the process is the basic executable entity that competes for the resources managed by MPE XL. The notion of many active processes sharing the resources of the computer system is fundamental to the efficient operation of the MPE XL operating system. By sharing the CPU and system resources among multiple active processes, resource utilization is greatly increased and system throughput improved. Process Management Programmer's Guide (32650-90023) provides you with information that will assist you in your development of programs that utilize process management capabilities available in the MPE XL operating system. This chapter describes processes and process management under MPE XL, and introduces process management capabilities and system intrinsics that MPE XL makes available to you. This chapter also describes the interactive session as a system-managed process, and introduces session management capabilities and system intrinsics that enable your program to create and abort interactive sessions.
