There are two virtual machines running it, one for computer center staff and the other for the computer science department to fiddle with. We (CC staff) have not done extensive evaluation of it that I know of, but at first glance it has several problems. -It communicates well only with IBM 3270 type terminals, whose architecture prohibits 'raw mode' type communication. All existing UNIX full screen programs (most sadly vi) are completely impossible to bring up. There is a full screen editor, but it is not anywhere near as useful as vi. -Even 'lint'ed C programs generally require modification to run under UTS. For some reason the Amdahl people have changed some specs of some system calls, including one of the ones to do with time. -From our point of view, it is sufficiently different from the UNIX that our people use all the time that it would require a lot of effort towards user-education to train them. I should point out we have really done very little it, and I am not one of the people with a say in our policy making. I think that there are a couple of people in the Computer Science dept who may be doing something useful with their machine. We have not run significant benchmarks or tests to see how CMS and UTS bog eachother down (that I know of). -Cliff
