Usually daytime MIPS usage starts local 8 AM and ends local 6 PM for certain workload. Processing of workload using z13 CPU would follow to process customer live data along the same time interval. Hourly MIPS usages from 8 AM to 6 PM are discrete numbers available from MICS post-processing of the SMF data. MICS can provide these discrete data up to 15 minutes interval but not finer than that. Using hourly averages helps to smooth curve from 8 AM to 6 PM in order to fit a polynomial to the discrete data. In this presentation we will fit a polynomial as high as fourth degree where the R-square value would be a best fit.
The fitting of a curve to the z13 MIPS data with higher R^2 value is the tool we use. For such a smooth curve fitting we would use appropriate workload processed by z13 processors.-Sudhir R. Nath-Wells Fargo Bank
