Hi Ron, I am sorry but I don't understand what you mean. We are a software development company so our work has no standard at all. It changes from day to day depending on what the developers are doing. We have a 2096 n02 which gives us 2 106(?) mips CP's. We have to run our sysplex testing by running sysplex under z/VM. We have the opportunity to hopefully get a 2098 g04, each processor will have 62.5 Mips (?) per CP. As I would like to be able to create a real sysplex and play around with various configurations I believe hat 4 CP's would be a very good idea. The PTB's are unsure and are worried that having CP's will be a big overhead. I don't know where they get this feeling.
I would like opinions, as to even worst case, we would be worse off if I kept current LPAR lay out on 4 CP's as against 2 CP's where all LPARs share CP's equally. I can't be very precise because the target changes day to day Crispin Hugo Systems Programmer, Macro 4 <http://www.macro4.com/> Macro 4 plc, The Orangery, Turners Hill Road, Worth, Crawley, RH10 4SS Direct Line: +44 (0)1293 872121 Switchboard: +44 (0) 1293 872000 Fax: +44 (0) 1293 872001 This message contains confidential information and is intended only for the -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Ron Hawkins Sent: 16 July 2010 16:11 To: IBM-MAIN@bama.ua.edu Subject: Re: 2 versus 4 processors Crispin, >From what you describe your z10 CPs will be kneecapped to 50% of your current z9 CP speed. That means that any compute bound task that runs at close to 100% of one CP is going to take twice as long to complete.
