Abstract

Conditional sharing of batch-processing computers between process jobs and batch processing is accomplished using this program. In a process job, one or more pieces of equipment is controlled and the computer may be utilized to background card duping, card listing, job stream input to disc and other jobs. In the batch processing mode, the stream originating from the principal input devices or from the job stream created on disc during a process job are acted on in the computer.

Program for Conditional CPU Sharing

Conditional sharing of batch-processing computers between process jobs and batch processing is accomplished using this program. In a process job, one or more pieces of equipment is controlled and the computer may be utilized to background card duping, card listing, job stream input to disc and other jobs. In the batch processing mode, the stream originating from the principal input devices or from the job stream created on disc during a process job are acted on in the computer.

At the start of the program, the process job mainline can be brought on line. It allows queueing of other programs. Such programs include: utility functions, process equipment program, process equipment support programs and process equipment related programs. The process equipment program can be run in common with the others.

To enable the process job mode to occur so that various process aware mainlines execute somewhat concurrently with the process equipment, the process equipment program is loaded into the storage in a specific common area. The process equipment operates by means of interrupts once it is started. Such functions include data logging and process equipment taken off-line. Support functions and equipment-related functions are similarly performed. These include process equipment masking, process equipment priority off-line, and process equipment restore and resume. Utility functions such as card duping, card listing, disc job stream input...
