In the 90s, I had done a project that required ten high-end rs/6000 servers (to handle workload that couldn't be handled by half-dozen large 3090s). However by middle of last decade ... there was that much processor power (one BIPS) in cell-phone processor http://en.wikipedia.org/wiki/XScale by comparison, recent z196 announce claims 50BIPS in maximum configured (80 processor) system http://www.foxnews.com/scitech/2010/09/01/ibm-unveils-worlds-fastest-microprocessor/ my first programming class was student fortran on 709. my first programming job was porting 1401 MPIO to 360/30 that had 64kbytes ... I got to design & implement my own monitor, devices drivers, interrupt handlers, error recovery, storage management, etc. low-end 360 were 0.0018 to 0.034 MIPs. http://en.wikipedia.org/wiki/IBM_System/360 and http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP2030.html -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
