The resource use functions of SRM attempt to optimize the use of system resources on a system-wide basis, rather than on an individual address space basis. The functions are as follows:

• Logical swapping - SRM automatically performs logical swapping when sufficient central storage is available.
• Working set management - SRM automatically determines the best mix of work in the multiprogramming set (MPS) and the most productive amount of central storage to allocate to each address space.
