This would have made it possible to spawn a service virtual address space ... without requiring a separate userid for every address space. however, before this shipped the group was redirected to do BSD unix for the pc/rt ... which did ship as "AOS". the later unix offerings were self-contained unix implementations that ran in single virtual machine virtual address space (not needing vm370 support for multiple independently running virtual address spaces). aix/370 was a port of UCLA Locus ... for 370 (along with companion part for aix/386) ... Locus had very sophisticated distributed computing support ... with executing application being able to non-disruptbly migrate between different machines in the network ... with some caveats even between different machine architectures ... aka between aix/386 and aix/370. one of the claims for aix/370 (and other unixes) running under vm370 ... rather on the bare machine ... was that field support required mainframe RAS & EREP to support the real machine ... and the effort to add such support to native unix was several times larger than the effort to do the straight forward port. -- 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
