Maybe TSO? Did > that do multiuser, without the need for VMs? after CSC came out to install CP67/CMS (and before I had done any major rewrites), IBM still had a TSS/360 SE onsite and I had to periodically let him use some of my weekend time. we put together a simulated interactive fortran edit, compile, execute benchmark (10 secs delay between every simulated terminal input; ... and cp67/cms had much better throughput and much better interactive response for 30 simulated users than tss/360 for 4 simulated users after I joined IBM and integrated all my CP67 enhancements and did more ... the CSC 768kbyte 360/67 was running 75-80 users (104 pageable 4kbyte pages after fixed kernel and my global page replacement). IBM Grenoble Scientific Center had a 1mbyte 360/67 and modified it to correspond to the 60s literature on paging working set dispatcher with "local LRU" page replacement (155 pageable 4kbyte pages after fixed kernel) running 35 users. The two user workloads were similar, but CSC had higher throughput and much better interactive response. Early 80s, Jim Gray had left SJR and joined Tandem and asked me if I could help a Tandem co-worker get his Stanford Phd ... which involved "global LRU" page replacement and the 60s "local LRU" forces were trying to block Phd involving "global LRU" ... Jim knew I had loads of my CSC CP67/CMS "global LRU" data as well as loads of Grenoble CP67/CMS "local LRU" data ... more than twice as many users with better performance but only 2/3rds the pageable real storage. -- virtualization experience starting Jan1968, online at home since Mar1970
