What is the difference between MIPS and MSU?

MSU is a metric that IBM originally created to normalize CPU utilization across different hardware configurations. While MIPS are calculated based on factors that are always open to interpretation, MSUs are calculated directly by the operating system, based on factors determined by IBM.

What is MSU consumption?

Fundamentally, an MSU is a unit used to measure the amount of CPU consumed per hour. For purposes of MLC charges, IBM has historically used the peak rolling four-hour average of MSU usage, as reported by the Sub-Capacity Reporting Tool (SCRT).

What is an IBM MSU?

(Million Service Units) An IBM measurement of hardware performance. One MSU is roughly equivalent to six million mainframe instructions per second (6 MIPS). IBM software is priced according to the power of the hardware in MSUs that it runs in.

What is an IBM mainframe MSU?

A million service units (MSU) is a measurement of the amount of processing work a computer can perform in one hour. The term is most commonly associated with IBM mainframes. It reflects how IBM rates the machine in terms of charging capacity. In fact, software charges are why the MSU measurement exists at all.

How many MIPS are in a MSU?

8.5 MIPS
If you compare our MSU and MIPS factor, you can see that 1 MSU = 8.5 MIPS.

How do I convert CPU seconds to MIPS?

To convert CPU seconds (accumulated consumption) to Mips (average consumption speed): Mips = (CPU seconds)*EUM/(Elapsed seconds) where EUM=EQUIVALENT UNIPROCESSOR MIPS as defined in the REXX exec below. Example: a job has used 100 CPU seconds during 1 minute (it is a multi-task job).

What is a MIPS IBM?

MIPS. We use MIPS to represent the capacity of the zSeries frame or LPAR. Early metrics tended to concentrate on the rate at which a processor executes instructions to represent capacity. One metric of this type is MIPS (millions of instructions per processor second).

How do you convert MSU to MIPS?

If you compare our MSU and MIPS factor, you can see that 1 MSU = 8.5 MIPS. On most processors, 1 MSU is between 8 and 9 MIPS. This is handy when I need to roughly convert between MIPS and MSUs.
