re: http://www.garlic.com/~lynn/2011d.html#52 Maybe off topic http://www.garlic.com/~lynn/2011d.html#54 Maybe off topic http://www.garlic.com/~lynn/2011d.html#55 Maybe off topic "Shoot-out at the OK Corral" ... (between QBE & SQL): http://www.mcjones.org/System_R/SQL_Reunion_95/sqlr95-Shoot-ou.html from above (QBE being in the field as an IUP) And there were people in the field, and they loved it. They had stories of tape librarians who'd automated their tape library with it, and Gene Trivett was going around and fixing some of the performance problems, and it was popping up all over the planet. So it had a very loyal following. It was obvious to everybody that this did something wonderful. That this was an end-user program. So then the question became, "So why don't we cancel System R?" or "Why don't we grow this thing?" ... snip ... a little later on in above: I don't have the exact date, but around 1978, right? When did the actual shoot-out occur? 1978? Gomory asked Dick Case to do a review of the work. Dick Case included Ashok Chandra, who currently runs the Computer Science Department - he's the latest version of Frank King - and one other person, who were all disinterested people, but were technically capable. They went to Yorktown and learned all about QBE, and then they came to San Jose to learn all about System R, and I gave them my long lecture about how the lock manager works and how Compare-and-Swap could do locking, and we did it all right, and we knew how to do Compare-and-Swap-Double. Dick Case was really impressed, because he's probably the architect of Compare-and-Swap. ... snip ... as I've posted before, compare&swap was invented by charlie at the cambridge science center working on fine-grain multiprocessor locking for cp67 (compare-and-swap was chosen because "CAS" are charlie's initials). we tried to get "CAS" into 370, but were rebuffed because the POK favorite son operating system people claimed that test&set was more than adequate. The challenge given us by the owners of 370 architecture was to come up with uses other than kernel multiprocessing. Thus was born were the uses for application multithreaded operation, examples that still appear in principle of operations. misc. past posts mentioning multiprocessor support &/or compare&swap http://www.garlic.com/~lynn/subtopic.html#smp some more QBE in discussion about VS/QUERY (QMF): http://www.mcjones.org/System_R/SQL_Reunion_95/sqlr95-VS_QUERY.html for other topic drift: http://www.mcjones.org/System_R/SQL_Reunion_95/sqlr95-Prehisto.html above mentions a project at cambridge science center. one of the people working on the project was the "L" ... in "GML" which was invented at CSC in 1969.
