HONE was online vm370 based system that grew into (the internal IBM) world-wide sales & marketing support (with lots of HONE clones all over the world) ... largely APL-based applications ... which is also largely inteterpreted code. misc. past posts mentioning HONE http://www.garlic.com/~lynn/subtopic.html#hone I had done the pre-cursor of vm DCSS ... basically a cms page-mapped filesystem with lots of bells & whistles about how things were page-mapped ... including all kinds of sharing. misc. past posts mentioning paged-mapped filesystem http://www.garlic.com/~lynn/submain.html#mmap this was heavily used by HONE ... starting for the APL interpreter ... i.e. the executable code. However, additional enhancements were done so that large portions of some APL workspaces (interpreted code) were also made "shareable". some old email relating to migrating the changes from cp67 to vm370 ... and then doing my own internal product distribution to large number of internal datacenters (including HONE). http://www.garlic.com/~lynn/2006v.html#email731212 in this post http://www.garlic.com/~lynn/2006v.html#36 http://www.garlic.com/~lynn/2006w.html#email750102 in this post http://www.garlic.com/~lynn/2006w.html#7 http://www.garlic.com/~lynn/2006w.html#email750430 in this post http://www.garlic.com/~lynn/2006w.html#8 later, a small subset of some of the features/functions (what is called DCSS, as well as some number of cms applications reworked to execute in read-only shared environment) were picked up and released to customers as DCSS. -- 40+yrs virtualization experience (since Jan68), online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
