Thanks for the comments about the site. The MIPS charts on it may be more or less use than you expect. The conditions of use speciically state that the whole disclaimer must be reproduced if any part of the chart is used - even one figure.
This may have the result I desire, of course. There are now two different MSU values for most modern systems - nominal and marketing. IBM's Software Division and the ISVs largely define the price/performance of mainframes these days, but they don't all use the same ones. Or even the same versions of the nominal ones. It is a fallacy - not worthy of a serious IT proessional - to pretend that the values stored by machines are any more accurate than any others. In fact, because they track the "marketing" MSUs, they're actually LESS likely to reflect a machine's true performance. Garbage In, Garbage Out - they're derived from lookup tables in the m icrocode that are just as fungible as my MIPS charts. And, IMO, much less satisfactory since the user has zero control over the change process. Or do people run standard jobs every month to check the reported MUSs? Not just after engineer visits - the microcode MSU values for any given processor can be changed in flight. I preferred IRARMCPU - I could see the SMP/E updates. As regards what IBM uses in discussions - MIPS and nothing else. I have IBM's MIPS values for all recent systems, and anyone who was at Klaus Goebel's preannouncement of the z890 at GSE last year will have seen only MIPS charts. That presentation is now public domain - if I can't find it on the GSE site I'll post it on mine. I have the same for the z990 and the z995 - and for something else. I currently have "nomail" set and I read the group via GOOGLE Groups, so copy me explicitly if you don't want me to miss it. -- Phil Payne +44 7833 654 800 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
