The insatiable hunger for MIPS comes mainly from the non-mainframe world. IBM uses MSU ratings for mainframes of all sizes, but folks who want to compare other hardware can only speak MIPS. So there are various charts available from various sources to make sense of apples and oranges. You get to pick your source and run with it. ;-(

I can run an IEBGENER to Print a SYSLOG file with 10,000,000 lines. My MIPS or SUs may vary across each iterating. If I change the CEC, it may change again, if I have more CPs or less, it may change again. It can be difficult to get a repeatable report of MIPs. http://www.ibmmainframeforum.com/all-other-tools/topic1988.html Postby Bill Dennis > Mon Jun 15, 2009 6:19 am The MIPS rating is based on processor type and Operating System. Performance guru Cheryl Watson offers several charts at http://www.watsonwalker.com/chart.html I'm not sure why you care about CPU MIPS rating because chargeback is usually by CPU time or Service Units used. Your job will run in less time on a faster CPU but the chargeback per second is usually more. Likewise, fewer Service Units are used on a faster CPU. So, knowing what you are trying to report would be helpful. Also, this may help. This is a specific product, but the terms and concepts may help (or not) http://www.ibm.com/support/knowledgecenter/SS8CCV_7.5.1/com.ibm.mams.doc/adminis tering_tamit/c_capacity_units.html Lizette > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] > On Behalf Of Greg Dyck > Sent: Wednesday, November 30, 2016 12:54 PM > To: [email protected] > Subject: Re: MIPS Calculation formula > > > Is there some formula to calculate a MIPS usage from the next kind > > of data- > source and volumes estimation: > > Keep in mind that MIPS stands for "Meaningless Indicator of Processor > Speed"... long used, usually misunderstood, and often abused.
