Impressions from the Fall '84 DECUS at Anaheim California

Some things (a small minority of what was there) that caught my interest.


On the demo floor:

VAX 8600 - the new large Vax was operating in a cluster with several other
vaxes.  It was impressively quiet.  The view inside showed a neat box which
should be easy to maintain. 

VAXstation-1  this was actually quite impressive.  The old VAXstation-100
(actually a terminal) looks sluggish in comparison.  This has a 256k bitmap
(2 video planes) in the microVax's memory.  The software demos had a few
rough edges, but nevertheless they showed impressive speed and a lot
of promise.  The had a Macintosh style "doodle" program which showed good
responsiveness between mouse and screen.  For those who missed the DEC
announcement of this it is a microVAX with a 19 inch mono display (same
display as VS100).  It runs full VMS and has a window manager, terminal
emulation (VT100, and Tektronix), and GKS graphics.

DECnet-Ultrix  They had a version of DECnet running on a 750 running DEC's
version of 4.2bsd Unix (Ultrix-32).  It worked: I tried file transfer and 
remote terminal.  It was running over an Ethernet and you could talk to any 
thing on the floor with it (VAX-VMS, VAXstation-1, DEC-20, Pro-350, 
RSX-11 etc.).

Ethernet bridge:  this was a box that connected the DECUS ethernet with one
in Boston and Nashua NH. (3 separate ethernets).  It would forward packets to
the other nets and keep local traffic and collisions from going out to the
other areas.  It used a satelite link (any type link would work).  It didn't
matter what protocols you put on the net (DECnet, LAT-11, and TCP/IP were
all running) since it actually transmitted ethernet packets.  Very clever
implementation.  I believed DEC designed the algorithm and a 3rd party
(I think the company was called Vitalink) implemented it on a 68000 under 
license.  (rumor was that DEC may sell its own box at some point).

At the sessions:

VAX/VMS V4.0 - lots of sessions on the new features of version 4.0.  They
said it was shipping and update customers should have it by Jan. 3rd.  Some
attendees said they had received it. (I haven't)

VAX 8600 - several sessions describing technology and speed benchmarks.
some rough numbers:
	Fortran		3.5 - 4.0 times 780
	Cobol		3.5 - 4.1 times 780
	Spice		3.5 times 780
	Finite element	3.5 times 780
	Whetstones:
		F 	4.6 MW		(Million whetstones)
		D	2.8 MW
		G	2.7 MW
		H	0.6 MW
	Multiuser mix: (1 part compute=fortran:little IO
		(2 part admin=dbms,datatrieve
		(5 part student=edit/compile/link/run)
		Speed	# users (for saturation)
	Student	  4	3 - 4		times 780
	Compute	  6	5 - 6		times 780
	Admin.	  2	3		times 780

TPU: a new editor for the VAX family.  This bears a strong likeness to
EMACS.  It is "high performance" (30% more throughput than EDT), has
100+ primitives, an extension language (Simple structured procedural
language) and comes with 2 front ends: EDT emulation and something called
EVE.  Multi-windows, multi-buffers, multi-pointers, -ranges.  Primitives to
manage VMS processes. Can run a process in a window. Can be "kept". Extended
pattern matching primitives. Picture mode; insert/overstrike;
jornalling/recovery; extension language interpreted or compiled; compiled
code is in sharable sections; fast startup.  Can be called and can call out
to any VMS program using calling standard.  Will ship with VMS V4.2 -
bundled with VMS (i.e. "free").  A Language Sensitive Editor (not bundled)
has been written on top of TPU.  The developers said "We share the same
philosophy with EMACS but we decided a simpler extension language (instead
of Lisp-like or TECO) was more appropriate."

VAX-ADA: was announced.  Claimed to be fast (1000 lines/min.) and would
produce very efficient code (comparable to existing high level languages on
VMS.)  Was certified in October by DOD.  "Production quality".  

Local Area Networking:  MS-DOS DECnet may be in the works (a'la IBM PC).  
DECnet running on Ultrix (on demo floor).  


These are a few of the things that caught my attention and I thought I would
share them with net-land.  Other DECUS attendees out there are encouraged to
do likewise.
