PC-GenoGraphics is a visual database/query facility designed for reasoning with genomic data. Data are represented to reflect variously accurate notions of the location of their sites, etc., along the length of the genome. Sequence data are efficiently stored and queried via a rather versatile language so that entire sequences of organisms will be treatable as they emerge. Other classes of information, such as function descriptions, are stored in a relational form, and joint queries relating these to sequence properties are supported. All queries result in visual responses that indicate locations along the genome. The results of queries can themselves be promoted to be queryable objects against which further queries can be launched.

Message passing is a common method for programming parallel computers. The lack of a standard has significantly impeded the development of portable software libraries for these machines. Recently, an ad-hoc committee was formed to develop a standard for message-passing software for parallel computers. This group first met in April 1992 at a workshop sponsored in part by the Center for Research on Parallel Computation (CRPC). Four of the attendees at that meeting produced a draft standard, henceforth referred to as the MPI (Message-Passing Interface) draft standard. After review by a larger group, and significant changes in the document, a meeting was held in November to discuss the MPI draft standard. This document is a result of those discussions; it describes a running implementation of in most of the proposed standard, plus additional routines that were suggested by the discussions at the November meeting.

This report focuses on the Battle Management/Command, Control, and Communication (BM/C³) element of the Global Protection Against Limited Strike (GPALS) system. The approach is based on the development and validation of a generic BM/C³ model. Central to the approach is the tenet that the design is divided into multiple layers. The critical functions make up the bottom layer, where trust is established and significant design effort is required.
