Distribution: world

Sorry for re-posting.
Since some people suggested that the original post was not clear enough
I'll try to be more specific.
I am looking for references to "real world" applications for real-time systems
with hard deadlines.
Basically I need the description of workloads, and any reference to
papers that describe control applications. The information I hope to
find are:
1) description of the task system (precedence graph)
2) information about max task durations (deadlines)
3) how may processors the workload is intended for
4) identification of critical tasks (vs tasks with soft or no deadlines)
Info on platform, language etc are not essential for our simulations since
they use only the task graph of the workload.
Any responses will be appreciated
Thanks
Axel
---------------------------------------------------------------------------
Papers describing such workloads are:

A paper by P.Shaffer (IEEE Control Systems June 1990)
"A Multiprocessor Implementation of Real-Time Control for a Turbojet Engine",
gives the computation graph for the control program of a supersonic turbofan
with afterburner is given. This is a 64 vertex graph, and for each the 64
procedures the max duration is indicated.

Subject: Inertial Nav / Space Lander Simulations
Hello All,
Is there anybody out there who has done a simulation of an inertial
navigation system and/or the guidance system for a lunar/martian lander?
I am a graduate student working on methods to provide a position fix to a planetary lander navigation system by recognition of known visual landmarks.
Eventually, I'll want to simulate the whole guidance system to show how the
position updates from the landmarks improve overall landing accuracy.
If anyone has any guidance system software or good references on the
subject, I would sincerely appreciate hearing from you.

I am a graduate student working in the area of Parallel Systems. My interests
in this area are scheduling, partitioning and load balancing aspects of
dynamic problem structures in irregular problem domains.
I am currently surveying PDES (Parallel Discrete Event Simulation) applications
and issues related to parallelising DES. My intent is to understand the needs
(from a parallel computing perspective) of PDES. Could you help me with
suggestions on references and/or prior work in this area? I am developing a
parallel runtime support environment on which I would like to test a few
applications that exhibit dynamic and irregular characteristics. Hence I would
appreciate any source code availability (even if sequential) by anonymous ftp
or otherwise. Please send e-mail directly to me as I read the newsgroups
rarely. I will make a summary of the responses on the newsgroup.
Thanks

Hello all,
I am interested in simulating frost damage of porous building materials.
In order not to reinvent the wheel I'd like to make an inventory of work
already done in this field.
I have a few questions which might be answered by readers of comp.simulation.
(1) Which models are used to simulate the geometry of porous materials?
Building materials like brick tend to have a wide range of pore sizes.
Building materials may be modelled macroscopically (using bulk
properties) of microscopically (taking into account pore morphology)
(2) Which transport mechanisms are incorporated?
Transport of heat, transport of moisture, coupled transport of
heat and moisture, etc..
(3) Which damaging mechanisms were incorporated?
Frost damage can be induced by a number of mechanisms: expansion
of water, ice lens formation, hydraulic pressure in pores, etc...
(4) Are any of these topics implemented in commercial or other software
packages?
Thanks in advance for responding. If there is anyone else interested I am
willing to summarize the responses.

Subject: Bug fix for tcplib, a library of TCP traffic model
Hello,
This is a bug fix message for tcplib, a library of TCP traffic models.
We apologize for any inconvenience that this message may cause you.
Vern Paxson of LBL noticed that "there's a rather huge spike in the UCB
ftp-data connections [of the trace data used in tcplib]. During that
particular day [when the traces was collected,] there were 2312
connections of 74 bytes each between the same two UCB and remote hosts.
[Ninety five percent] of these connections came between 30 and 45 seconds
apart. None of the other datasets showed this sort of traffic so it
clearly appears to be anomalous."
Fortunately for us...the anomaly did not show up in either our SIGCOMM or
Journal of Internetworking papers because of the way we grouped multiple
ftp-data connections into one conversation.
We have taken out the anomalous data from the two data files:
ftp.nitems
ftp.itemsize.
Both are available on jerico.usc.edu (128.125.11.6) for anonymous ftp,
in the directory pub/jamin/tcplib. These files are meant to replace
their namesakes in the tcplib/data. To update your libtcp.a, remember
to do a make in your tcplib directory after you replaced the two files.
Alternatively, you can get the new library or the whole set of sources
from jerico.usc.edu:pub/jamin/tcplib as described below. The papers
[Caceres91] and [Danzig92] cited in the tech report are also available
for anonymous ftp from jerico.usc.edu:~ftp/pub/jamin/traffic. The file
traffic.ps.Z is for [Caceres91] and the files journal.part[1-4].ps.Z
are for [Danzig92].
=======================================================================
The following technical report and the source library it describes are
available for anonymous ftp from jerico.usc.edu:~ftp/pub/jamin/tcplib.
(Jerico's IP address is 128.125.51.6.) The directory contains the
following files:
README
libtcp_ds31_ultrix41.a.Z
libtcp_hp90_hpux847.a.Z /* not supported anymore because we
lost access to our hp machine. */
libtcp_sun3_sunos411.a.Z
libtcp_sun4_sunos411.a.Z
brkdn_dist.h
tcpapps.h
tcplib.1
tcplib.tar.Z

All you need to transfer to use the library are: README, brkdn_dist.h,
tcpapps.h, tcplib.1, and one of libtcp* that matches your setup. You

tcplib: A Library of TCP Internetwork Traffic Characteristics

USC-CS-91-495
1. Introduction
When simulating computer networks, it is necessary to specify the
traffic between network nodes. Typically, simulation studies of
wide-area tcp/ip networks model traffic as a combination of Poisson
processes and maximal rate streams--corresponding to telnet traffic
and large file transfers respectively. Such traffic models are
justified when the modeler wants to show, for example, that his flow
control or gateway scheduling algorithm responds well to worst case
traffic or when essentially nothing is known about the real network
traffic. However, such models do not reveal how similarly robust
algorithms respond to the common case load.
This paper describes tcplib, a library to help generate realistic
tcp/ip network traffic. Tcplib is motivated by our observation that
present-day wide-area tcp/ip traffic cannot be accurately modeled with
simple analytical expressions, but instead requires a combination of
detailed knowledge of the end-user applications responsible for the
traffic and certain measured probability distributions [Caceres91].
We collected three-day traces of wide-area Internet traffic at UC
Berkeley, University of Southern California, and Bell Communications
Research. Our study identified that out of more than 35 different
application programs, ftp, smtp, nntp, vmnet, telnet, and rlogin are
responsible for 96% of wide-area tcp/ip bytes. Two related studies,
one at University College London and the other at Lawrence Berkeley
Laboratory, identified a subset of these six applications as
responsible for most of their wide-area tcp traffic [Crowcroft91]
[Paxson91]. Tcplib models five of these six applications. It excluded
vmnet, an IBM mail exchange application , because it was absent from
three of the five traces. Furthermore, since telnet and rlogin have
essentially the same characteristics, we have included in tcplib only
routines describing telnetUs. Additionally, we included characteristics
of phone conversations based on the study reported in [Brady65] and a
distribution of conversations composition breakdown derived from several
stub-network traces.

Subject: PARALLAXIS: New Tools
___________________________________________________________________
THE P A R A L L A X I S MASSIVELY PARALLEL PROGRAMMING SYSTEM
___________________________________________________________________
-------------------------------------
Announcing New Tools for Parallaxis
-------------------------------------
Parallaxis is a procedural programming language based on Modula-2, but extended
for data parallel (SIMD) programming. It has been developed at the Universitaet
Stuttgart (Germany) and is in the public domain since 1990. The main approach
for machine independent parallel programming is to include a description of the
virtual parallel machine with each parallel algorithm. The declaration includes
the number of identical processors with local memory (PEs), the names of com-
munication ports, and the network topology for data exchange among PEs. With
this information contained in each program, the parallel algorithm becomes
simpler (e.g. symbolic names for communication directions) and easier to
understand.
The Parallaxis environment provides both, a simulation system for several work-
stations and PCs, and compilers for the massively parallel supercomputers
MasPar MP-1 and Connection Machine CM-2. Parallaxis programs may be tested
and debugged on the simulation system and can then be executed on a MasPar
or CM system without a change. The simulation system by itself is a valuable
tool for educational purposes, such as parallel programming classes.
The Parallaxis compilers for MasPar and CM provide full virtualization for
both, processing elements and interconnection structure. Application programs
have no limitations in terms of PEs or connections available besides memory
size.
New Tools are now available for Parallaxis:
-------------------------------------------
------
pmon An X window based load monitor for Parallaxis programs.
------ During execution of a Parallaxis program, a recording file may be
generated. This is being read by pmon, which generates a graphics
window showing the load of the processing elements as a function over
the execution time. Some statistics information on the commands executed
may be displayed in form of a pie chart (e.g. percentage of data
exchange commands).
pmon is a very interesting analysis tool for parallel algorithms, each
revealing its characteristic "load curve". It is helpful in determi-
nating where time is spent (or lost) for tuning parallel programs.
------
visu An X window based interconnection structure visualizer for Parallaxis.
------ When using complex connection structures between PEs in a Parallaxis
program, it is often helpful to have them displayed in graphical form.
visu reads a Parallaxis source program and displays the PEs and their
connections in a graphics window. The PE arrangements currently suppor-
ted are: linear list, grid, and circle. PEs are displayed as polygons,
depending on their connection number. The positions of connection ports
may be edited interactively. PEs may be labelled with their position
numbers.
Both tools are bundled with the appropriate workstation distribution tar-files
for: Sun3, SPARCstation, DECstation, HP/Apollo 700, IBM RS/6000.
All software packages and a number of example programs are available
via "anonymous ftp" from our
-------------------------------
server: ftp.informatik.uni-stuttgart.de (129.69.211.1)
in subdirectory: pub/parallaxis
-------------------------------
The User Manual for Parallaxis Version 2.0 is also available via "anonymous
ftp" as Postscript files, but a printed copy may also be ordered for a nominal
fee (cash or cheque made to "Univ. Stuttgart") of DM 10.00 (Europe) or
