Help!
I'm trying to compile a table for use here at the University that
summarizes, to some extent, different computer platforms. I have
a little bit of information about machine performance--although
I've found getting something like SPECmarks on non-unix platforms
fairly difficult.
The "other" side of the issue is numbers of users a machine can
handle.
What I'd like, is to hear from other sites and try to get an
idea on the number of users actually using different machines
concurrently. In other words, what machines are you running
and what's an "average" number of users? I'm particularly
interested in any sites that run "large" (>5) numbers of users
on Workstations (we don't).
Here's a synopsis, by the way, of our site:
Computer Memory Disk #accts Avg # users (Mips) O.S.
IBM ES9000-210 128Mb 10000Mb 1020 200 (14?) MVS
VAX 6310 32Mb 1800Mb 630 30 (10?) VMS
IBM 9375 16Mb 1600Mb 470 40 ( 7?) CMS
MicroVax-3500 16Mb 1400Mb 110 10 ( 6?) Ultrix
MicroVax-II 11Mb 113Mb 160 10 ( 4?) Ultrix
Type of use:
IBM ES9000-210 mostly on-line transactions, production programming (cobol)
VAX 6310 academic research and instruction
IBM 9375 email (PROFS) and instruction
MVAX-3500 academic research and instruction
MVAX-II instruction
We have, as you might expect, other machines (DECStation 3100, Apollo
DN1000, IRIS 4D25G) but they are typically running with very few (<3)
users at a time. Where do most sites put most of their users? (And
why?) ((Is there any reason--providing unlimited licensing is available--
not to run lots of users on workstations?))
If there is any interest in this I'll summarize.
Thanks! John Campbell CAMPBELL@NAUVAX.UCC.NAU.EDU

unix? Sure send me a dozen, all different colors.
