There was fantastic SE on financial institution account in LA ... he wrote ATM cash machine support in VM370 that he showed had higher throughput on 370/158 than TPF ran on 370/168. His trick was significant better disk arm scheduling (than TPF) ... had patterns of ATM useage and record layout ... and do things like delaying transaction somewhat proportional to the record location distance from current arm position and the probability another transaction would come in needing a record closer to the current arm position. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
