Apr 06, 2016 · CPU seconds to MIPS conversion example. A mainframe job has used 100 CPU seconds during one minute -- it is a multitask job. The system is an IBM 2064 Model 1C5 (1085 MIPS, EUM = 217 MIPS).The average consumption speed of this job is 100 x 217/60 = 362 MIPS.. Cutting CPU costs on the mainframe and improving the system's operational efficiency, however, are not always the same …Estimated Reading Time: 4 mins

In the GETS environment, the unit of measure for application jobs that run on the mainframe is central processing unit (CPU) hours. This is not to be confused with clock hours, which measures the total elapsed time for processing. The CPU may only process a …

Mainframe hardware: Processing units. Mainframe concepts. Early mainframes had a single processor, which was known as the central processing unit (CPU). Today's IBM® mainframes have a central processor complex (CPC), which may contain several different types of z/Architecture® processors that can be used for slightly different purposes.

Mainframes working after hours: Batch processing. Batch applications are processed on the mainframe without user interaction. A batch job is submitted on the computer; the job reads and processes data in bulk— perhaps terabytes of data— and produces output, such as customer billing statements. An equivalent concept can be found in a UNIX ...

So, I need to convert CPU seconds to MSUs, 4HRA MSUs, or MIPS (depending on how the client is paying). Let's take MSUs to start. My first step is to go to the IBM Large Systems Programming Reference (LSPR). I find the client's mainframe processor model, and look it up here. Let's say our client has a 2964-725: a z13 with 25 full powered processors.

Traditionally CPU seconds, or the number of seconds a CPU is actually in use, was a measurement of how much work a processor performed. CPU seconds was, and often still is, used as a measurement for charging mainframe usage. z/OS records the number of CPU seconds that each unit of work has consumed, providing an excellent way of measuring the ...
