Papers may deal with simulation on systems ranging from geographically distributed computing systems to tightly coupled multiprocessors and SIMD machines. Specific topics of interest include, but are not limited to: * Methods for distributed, concurrent simulation, discrete or continuous * Concurrent simulation methods for particular classes of systems (e.g., neural networks, electronic circuits, weather, computer systems and communication networks, military applications) * Concurrent graphics and animation for simulation * Concurrent real time simulations (e.g., flight simulators, robot control) * Machine architectures for concurrent simulation * Programming constructs and languages for concurrent simulation * Performance evaluation methods for concurrent simulation * Empirical performance evaluation studies * Real Time Simulation Papers are due July 31, 1989. Authors will be notified of acceptance by September 30, 1989. Camera ready copy is due October 31, 1989. Papers must be in English and will be limited to 6 pages in the conference proceedings. Papers must contain original contributions to the field that have not been previously reported in the literature. Papers that contain incremental improvements of previously published work should clearly indicate new aspects of the work in the abstract. Each submission should include the name, complete address and phone number of each author. Send six copies of the full text of papers to: Dr. David M.

I am going to examine the papers which you mentioned. My own view is, which I have developed almost to completion, is that scheduling and unscheduling are *efficient* mechanisms of enforcing the logic of something more abstract, namely, causality rules which refer to the future of causing events. An example of such a rule is: An event of putting a kettle of water on the fire causes an event of water in it to boil at a future time provided it is not taken off the fire in between. Now, if an event of putting a kettle of water on the fire occurs, an event of its boiling can be scheduled. But if the kettle is taken off the fire in between then the event can be unscheduled. Recognizing that this is the purpose of scheduling/unscheduling one can separate it from the causality rules and make it part of the simulation procedure (or inference engine for causality rules). The model itself can consist of declarative causality rules. The separation of logic from control which results is extremely beneficial. In existing models scheduling and unscheduling appear in the main model itself, thereby obscuring the logic of the causality rules which the modeler probably had in mind. Of course, scheduling/unscheduling are not the only way to perform inference with causality rules. Thus, they can be dispensed with altogether. These ideas are discussed in a paper on the DMOD (Declarative Modeling) system, which is under development. A primitive description of it appeared in this year's AI & Simulation conference. The paper under development contains a much better presentation. I would be happy to send it to you or others who may interested, when it is done. Comments are invited. Regards. Sanjai Narain Rand. ------------------------------ Date: 8 Jun 89 07:40:00 EDT From: "Robert Breaux" Subject: UNIVERSITY RESEARCH INITIATIVE (URI-90) To: "simulation" You may be interested in the ODDDR&E(R&AT/RLM) Secretary of Defense "University Research Initiative Research Initiation Program" brochure, soliciting proposals in the $50 - 250 K range from universities which traditionally do not receive much DoD funding? The brochure comes from the office above, Room 3E114, the Pentagon, 20301-3080, with a due date of 14 Sept 89 for proposals. Each military service plus DARPA have areas of interest. Universities already receiving $4M or more from DoD are ineligible. One emphasis is to increase University instrumentation, so they are looking for proposals with more than 10% cost devoted to instrumentation. Here are excerpts from the brochure on the Areas of Interest: Army: "smart materials and structures. . . including materials science, electronics, biosystems, earth sciences and math modeling . . . and other mathematical issues related to design and performance of smart materials and structures." Navy: ". . . coordination in hierarchial team decision making. . . variables that enhance coordination and enable teams to maintain coordinated action under stress conditions characteristic of tactical environments. . . [such as] command and control of tactical units in a battlegroup. . . resource allocation decisions . . .[using] incomplete and uncertain information, with limited intra-team communication in fast-tempo, high-risk threat scenarios. A central scientific issue is the development of measures or indices of coordination. . .[including]team organizational structure, degree of overlap in team member "mental models, design of display interfaces common to the team members, access to global vs. local databases, role of the team leader as coordinator, adaptive coordination strategies, and tradeoffs between explicit (communication) and implicit (computation) coordination." Air Force: "microstructural design, processing, and characterization of materials" DARPA: "applied mathematics. . . wavelets and their application. . . [to] fractals, the fractal measure of noise, partial differential equations, and signal processing of speech and images . . ." __________________________________________________________________ Of the above, I figured the "Navy" work came closest to your interest, so I was quite brief on the others. Of course, the Navy stuff is from the Cognitive Psychology group. Within "simulation", this applies mostly to the training device speciality. Navy POC is Dr. W. S.
