CLS SCHEDULER, SYSTEM_MANAGEMENT, CPU Class Scheduling

CPU class scheduling has long been available on IBM operating systems. This
capability was implemented as of OpenVMS V6.0 within the OpenVMS scheduler

are available for customers to write their own CPU class scheduling policies. 
This article discusses some potential uses of class scheduling and the callouts
available to system programmers for writing a class scheduler policy.

A sample CPU class scheduler is provided.
