Tandem's T16 series of machines were stack machines and in the old days when their CPUs absorbed boards of logic and were rated in the 1 MIP range, their ability to context switch meant big advantages in being able to throw and catch I/Os, certainly far more than most modern RISC machines do per MIP today. But even Tandem has moved on to modern tech (MIPS, hi John!) and feel pretty good about it. Certainly the user interface moves along a lot better than it used to and they've fixed whatever worries they had about being able to orchestrate the I/Os per second that their environment requires. (I was a rookie Tandem sys admin some time ago and the Guardian networking had some problems with congestion at high loads, running out of static structures, etc. The big office VLX went nuts at 5:00 on a Friday and the advice given to me was to just "shut the power down and turn it back on again, don't bother to reboot it"... It worked...) -- Dave Fuller All opinions expressed are my own and not Sequent Computer Systems those of Sequent Computer Systems, Inc. dafuller@sequent.com
