Subject: cellsim_1.5 available via ftp
Cellsim_1.5 available for testing.
Version 1.5 of the Cellsim cellular automaton simulator for Sun
workstations is now available via anonymous ftp. This is a
window-based CA simulator allowing interactive specification,
editing, running, and analysis of 1- and 2-D CA's. It will
run on Sun-3's, -4's, and Sparc stations, color or B&W.
Version 1.5 is a beta-test for version 2.0 which we will
release at the end of the summer. Thus, unless you are desperate
for the black and white version in 1.5, you might wait for 2.0.
Of course, we are releasing 1.5 in the hopes that some people will
pick it up and pass us back suggestions or bug-reports.
Primary improvements over 1.0 are:
1) black and white version using textures instead of colors.
2) Margolus neighborhood has been added.
3) most parameters remember previous settings so one doesn't
have to reset them every time a function is selected.
4) various bugs have been fixed, including:
- proper random configuration generation.
- closeup for 1-D CA's now zooms in on center of
current configuration instead of on center of
time-trace.
5) images and transition tables can now be saved and loaded
in compressed format.
6) images can be saved in CAM6 format.
7) more sample rules and images have been supplied, mostly illustrating
the Margolus neighborhood.
8) Default directories are allowed for Transition tables, Images,
and Color-maps. These may be reset by changing an environment
variable.
9) zoom in/out buttons have been added to simplify magnification.
Features which will be supported in 2.0 which are not in 1.5 include:
1) computed functions over 256 states: users will be able to write
simple functions in C or Fortran which will compute the next state
rather than use a look-up table. These will be dynamically linked
from the simulator. This is a really useful feature which may
slow down the simulation a bit, but greatly expands the range
of applications of the simulator.
2) user-specifiable neighborhood templates, which will allow
arbitrary neighborhoods and the selection of arbitrary bits
from each neighbor.
3) a Connection Machine module which will interface Cellsim to
a CM2, allowing arrays to be run, displayed and analyzed
on the CM2.
Together with the computed function and user-specified
neighborhood facilities, this may ultimately be expanded into
a more general tool for running locally determined, spatially
distributed systems on the CM, allowing more complex models
than one would want to embed in the CA formalism. Computed
functions will probably have to be written in C/Paris.
4) Laserwriter dump of array configurations.
5) read/write rules in CAM6 format.
-------------------------------------------------------------------
Obtaining V1.5:
A) FTP access on the internet:
Cellsim_1.5 is available in compressed tar format via anonymous ftp
from 128.165.96.120.
create an appropriate directory on your own machine, then:
ftp 128.165.96.120
login as anonymous and give your email address as password
cd to the "pub" directory
set binary mode
set hash marking if you want to see that the transfer is working
get "cellsim_1.5.tar.Z"
you should receive 169887 Bytes
get out of ftp ("bye")
uncompress cellsim_1.5.tar.Z
untar cellsim_1.5.tar
read the README, cell.doc, examples.doc, and V1.5.changes files
for information on how to use the simulator.
B) From Japan, you can try the internet access listed above, or you can
contact Nobuyasu Osato, who should have a copy in a week or two (i.e.
by mid-august):

C) In Europe, annonymous ftp access will be available from 130.236.1.3

D) Otherwise, if you REALLY want version 1.5, send me a 1/4"
cassette tape or a reel tape specifying the preferred
format (e.g. 1620 BPI for reels or whatever) and I will
return a tar'd version of the simulator. Don't send any
money! The service is free! If you can wait a month or
so, and you aren't interested in testing 1.5, version
2.0 will be out at the end of the summer (~mid-september).
It should be worth the wait, as it will include the much
more powerful computed function facility.

Subject: GPS Sim.SW for Workstation
To: <simulation@bikini.cis.ufl.edu>
For a lecture I am looking for a general purpose simulation SW (type SLAM II
/SIMAN) running on a worstation like : >>> Macintosh II (1.PRIIORITY)
Sun worstations (2.priority)
IBM PS/2
If you know any SW of this type, or somebody who might know, please let me
know !!
Thank you for your help !
[[SLAM II and SIMAN both run on SUN workstations, and I believe that they
have PC packages as well. For lecturing purposes, you might want to consider
SMPL or CSIM. SMPL is available by FTP to our mailer machine, and CSIM
is available from Herb Schwetman at MCC. -PAF]]

Subject: Conference announcement
Dear Collegue,
Planning is now underway for the 1990 Eastern Multi-Conference (EMC) on
Computer Simulation sponsered by the Society for Computer Simulation,
International (SCS). The 1990 EMC will be held April 23-27 in Nashville,
Tennessee. As chairman of the conference on Ballistics Simulation I am
soliciting ideas, suggestions, and contributions for group leaders,
panels, and papers. I would like to invite you to present a paper or to
participate as a group leader, a session leader, or a session discussant.
The 1990 EMC promises to be one of the best yet. The subject material
runs the gamut of industrial, commercial, and government interests. As
Ballistic Simulation Conference chairman I urge you to participate. I am
interested in your ideas, your interests, and your active participation
in what has come to be a premier event.
Please, consider presenting a paper or participating as a group leader, a
session leader, or a session discussant and if you have some good ideas,
send them to me. Enclosed is an overview of the subject areas that I am
looking for participation in. If you are interested in any of these
areas, please consider actively participating in the conference. If you
have any other areas that you would like to sponser, please send me a
session proposal. If you know of others that may be interested in serving
as a group leader, a session leader, or a session discussant, please pass
this letter and enclosure on and let me know of their potential interest.
Thank you again for your kind consideration.
Sincerly,
