We have to hand feed the two systems. If you really want this on comp.unix, please post directly to their moderator.] Steve, please pass this reply on to Tim Raymond (traymund@uiuc.edu). It's in response to a posting he put in comp.unix through you. Thanks, Bob -------------------------------------------------------------------- In article <1991Mar11.132225.13679@hubcap.clemson.edu> you write: > > We've gotten a good offer from Harris on a NightHawk 4400, an > 88100 based realtime unix machine. This offer competes with an > offer from DEC on a DECstation 5000. Tim, while I am certainly biased, you might check out Data General's 88100 based offering (AViiON). There'll be a major anouncement in New York tomorrow that will be simulcast to San Francisco, Brussels, and Toronto that may be of interest -- depending on what you're looking for short- and long-term. I'll try and answer some of your questions for DG's AViiON product. I'm in engineering, not marketing, so I don't know what the deal is with price, et al, only the metal and s/w. > 1. What's the SPEC rating (or MFLOPS) of the 4400 as offerred? For the AV/310 uni 20MHZ - SPEC is 9.7 For the AV6200 uni 25MHZ - SPEC is 12.7 (25 Dhrystone MIPS/CPU) For the AV6220 dual 25MHZ - SPEC is 24.0 (ditto) See tomorrow's announce for latest (or ask me after tommorow). This is with two 88220 MM/cache chips/cpu with separate data/instruction ports and 4-way, set-associative 16KB caches. > 2. Are we getting: > SCSI interface? Yes. 322 MB 5.25" SCSI Winchester disk (1.5 MB/sec data xfer, 18ms mean seek). > Eithernet interface? Yes, IEEE 802.3. > A good FORTRAN compiler? I don't use Fortran, so I don't know what good is ... but there is a fortran compiler available. > A console/workstation? (color or bw) Workstation/mouse/kybd, or console. > 8mm tape drive? 150 MB QIC cartridge is default. Multiple configurations available based on what you're looking for and, I'm sure, price. Generally ... 10 VME slots 208 MB ERCC (1 Mbit DRAM) max mem 512 - 640 asyn connects Can't talk about max cpu's till tomorrow. > 3. Does their UNIX support NFS? Network File Serve: allows disks to Yes. DG/UX is BCS, SVID 2 and POSIX 1003.1 compliant. Current release (4.32) is based upon SVR3 with BSD 4.3 extensions (such as BSD signals). It also supports Sun RPC's and NFS, X11R3 (R4 coming soon), and OSF Motif. DG/UX is allows fully symmetric multiprocessing. > Does it include X11R4? X11 is a standard windowing system used X11R3 with Motif is presenly released. X11R4 to be released soon. Can't talk this about yet. > 4. What will it cost in maintenance: hardware and software? Currently Sorry, don't know anything about this stuff. > Potentially, a 4 CPU version of the 4400 could be almost 10x the > speed of the 3100. That's quite a bit of raw computing power... Wait until Wedesday's announcement. You'll be happy! Don't know if any of this is what you were looking for, Tim. If not, just send to /dev/null and that'll fix it. - Bob rprimmer@lemond.webo.dg.com Data General Software Engineering -- =========================== MODERATOR ============================== Steve Stevenson {steve,fpst}@hubcap.clemson.edu Department of Computer Science, comp.parallel Clemson University, Clemson, SC 29634-1906 (803)656-5880.mabell
