Comparison to the number of CPs is quite obvious, but 1.) Number of SAPs is related to the number of BOOKs/drawers, not to the number of active CPs. 2.) Why we compare number of SAPs to the number of CPs at all??? Shouldn't we compare number of SAP to the I/O configuration? (backgound note: I

Re: Why sort (was Microprocessor Optimization Primer)

An excellent synopsis of mainframe history. It follows that most mature shops use SORT extensively because until recently, the platform pretty much required it for reasonable performance as measured by wall clock. One could argue--maybe even prove--that today's DASD allows more random updating

Re: Why more SAP processors?

If we compare the maxed out base and high end models of the z10, z12, and z13 we do see a trend, but it’s a downward ratio…fewer SAPs per CP. Of course you can vary the ratio to suit your business, but consider the following. If my arithmetic is correct, the z10 base had a 4:1 CP to SAP
