re: http://www.garlic.com/~lynn/2017d.html#40 What are mainframes http://www.garlic.com/~lynn/2017d.html#41 What are mainframes http://www.garlic.com/~lynn/2017d.html#42 What are mainframes part of the reason that IBM went with UCLA Locus for aix/370/386 ... say instead of mach/afs ... is that Locus did things like transparent process migration (even across differeent architectures under some restrictions) as well as partial file replications. https://en.wikipedia.org/wiki/Locus_Computing_Corporation AIX of IBM PS/2 and System/370 https://en.wikipedia.org/wiki/Locus_Computing_Corporation#AIX_for_IBM_PS.2F2_and_System.2F370 For OSF/1 there were attempts to try and merge features of CMU mach/afs and UCLA Locus https://en.wikipedia.org/wiki/Open_Software_Foundation computeworld 18May1992 https://books.google.com/books?id=PUMJFIR4RGcC&pg=PA12&lpg=PA12&dq=ibm+osf/1&source=bl&ots=yVK5vEotYF&sig=W10rQG0pUJTnotiGvXgdD6nQg7E&hl=en&sa=X&ved=0ahUKEwj2vdqe7pPTAhVK4WMKHQiKAgYQ6AEIZDAQ#v=onepage&q=ibm%20osf%2F1&f=false Although IBM had once planned to run OSF/1 on its Personal System/2 line, today only OSF/1 commands and libraries are integrated in the AIX/ESA ... snip ... trivia ... the following computerworld page above has article about "meaner, leaner PC strategy" by head of Boca/PC ... formally POK mainframe executive.
