re: http://www.garlic.com/~lynn/2012h.html#59 How many cost a cpu second? and in much the same way that the 60s virtual machine, online service bureaus worked hard to have the mainframe cpu meter come to a stop ... the drastic reduction in machine costs in modern mega-datacenters is also big driving factor in redesigning processors to drastically reduce electricity useage when they aren't actually doing processing (with drop in machine costs, electrical useage is becoming a much larger percentage of total cost of ownership). -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
