>zPCR modelling? That's akin to saying a Sysprog only needs SMP/E skills.
zPCR is only as good as its input, and LSPR does not try every possible configuration, including some they have figures for. What is missing is extrapolated, usually linearly, which is not how the MP effect works. Capacity Analysts have been aware, for almost 20 years since I first started seeing press about it, that relative capacity comparisons are, at best, an estimate. And, with more powerful processors, the variance in capacity has taken even larger swings. Unfortunately, even MSU ratings are suspect (with/without the 'technology dividend'). And, the scariest part is the fact that Senior Management is committing millions to these guesses. - Ted MacNEIL [email protected] ---------------------------------------------------------------------- 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
