We have one of the first Max's, that's why we have 032's instead of 332's. The Max we have handles student programming and handles 64 users with very little slow down. The worst load average we've seen without TRYING to overload the machine is about 6 or so. When we ran parrellel make we tweeaked it up to 13.9x. The new CPU boards are supposed to offer a nocticable improvement. We've beta tested alot of their new kernels and Encore has ALWAYS responded quickly to problems we've found, usually by having our crash dump federal expressed to them overnight. For a commercial site UMAX 4.2 should be VERY stable, we mix equipment horribly here which has caused most of the problems. If you stick with Encore equipment ALL the way you won't have very many problems. > >We are currently evaluating machines in order to buy a machine of this >sort.

Pascal, fortran and C all allow access to the parallel routines. If you have any specific pointed questions you'd like to ask let me know via email and I'll answer them as best I can. -Rob Healey rhealey@ub.d.umn.edu #include Nobody ever listens to me anyways, why should they share my opinion? It's mine, ALL mine and you can't have it... Well, maybe if you ask REEEEEEAALL nice.
