Can I calculate the total MIPS consumption for batch jobs ?

Hi Supports,

As captioned, can I based on the CPU usage figure in the JES2 job logs, to sum up all of them, and then to say now the batch jobs have consumed a certain amount of MIPS !?

From Internet I found something below. Do they say the things for me !?


"Example: A job has used 100 CPU seconds during one minute (it is a multi-task job). The system is a 2064-1C5 (1085 MIPS, EUM=217 MIPS). The average consumption speed of this job is 100*217/60=362 MIPS"

No.
  1. MIPS is an obsolete measurement; IBM no longer quotes a MIPS figure for its machines.
  2. MIPS only ever referred to the entire system, not any of its operations. This calculation is bogus.

Hello and welcome to the forum,

As mentioned, you cannot calculate MIPS.

However, there are many measurements possible. Much of this info can be retrieved from the SMF data (if you are not familiar with this, ask your system support).

Many (most) organizations have processes in place to keep track of what resources (i.e. cpu) is being used and by what. Many create "friendly" files so one can write their own reports.

Why has someone brought up MIPS? If you explain what you want as "output" someone may have a suggestion.
