Itschak, Simply speaking here......very simply......
Wouldn't a simply rule be throughput. 1 cpu cycle = 1 wall sec 2 cpu cycle = 1 wall sec So I can process twice the work with two cpus, giving that the engine speeds are consistent. However a single engine twice as fast as two slower engines, would acheive the same results. So now it workload related. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Itschak Mugzach Sent: Tuesday, June 06, 2006 2:47 PM To: IBM-MAIN@BAMA.UA.EDU Subject: One or two CPUs - the pros & cons I wonder if there is a document that describes guidelines or rule of thumbs when selecting machine configuration, engine wise. I mean, if you get the mipsage on a uniprocessor, why have it on two? your advice is welcome.
