Evaluation and Recommendations for Technology Insertion into Technical Order
Maintenance
As the need for mission-critical software systems increases, Post Deployment
Software Support (PDSS) activities will require increased priority in planning.
PDSS is "the sum of all activities required to ensure that, during the
production/deployment phase of a mission-critical computer system's life, the
implemented and fielded software/system continues to support its original
missions, and subsequent mission modifications and product improvements. PDSS,
therefore, includes not only software "maintenance" but also the activities
required for overall system support.
The SEI recognizes the importance of PDSS activities in the life cycle of
mission-critical systems. In March 1986, SEI personnel met with
representatives of the Air Force Logistics Command (AFLC) at Ogden Air
Logistics Center (OO-ALC), Hill Air Force Base, Utah, to determine if there
were areas in PDSS that the SEI could address. The AFLC representatives
described the activities performed at Air Logistics Centers and problems
encountered in those activities. As a result of this meeting, the SEI
authorized a feasibility study to determine how it might best interact with the
PDSS community. This report, written in August 1987, describes the evaluation
process and the ensuing recommendations for technology insertion into technical
order maintenance.

Introduction to the Serpent User Interface Management System
Serpent is an example of the class of systems known as a User Interface
Management System. It uses the X Window System to interact with the end user,
and is useful both as a portion of a production system and as a separate
prototyping tool. Serpent supports the development and execution of the user
interface of a system. It provides an editor with which to specify the user
interface and a runtime system that communicates with the application to get
the data to display. The system then uses the specification previously output
from the editor to decide how to display that data. This report provides a
technical overview of Serpent, its components, the module used in specifying
the user interface, and the editor used in constructing the user interface.

Serpent Runtime Architecture and Dialogue Model
This paper describes the runtime architecture and dialogue model of the Serpent
User Interface Management System (UIMS). Serpent uses existing software systems
to create a UIMS based on a structured production model to specify the
dialogue, and uses a database approach for communication between its internal
layers. The model for the dialogue in Serpent supports simultaneity of
subdialogues and presents the dialogue specifier with a model that views data
as mapping from the application to the presentation. The database approach for
communication between the layers provides a model that application programmers
understand well and find easy to use. The approach also provides the power
necessary to decouple the application structures from the structures implicit
in the user interface.

The Project Management Experiment
This report covers a project management (PM) experiment, one of six experiments
that examine different functional areas of Ada programming environments. The PM
experiment was designed as part of the Evaluation of Ada Environments Project.
This report describes the environment-independent part of the experiment: the
activities covering the functional area, the evaluation criteria, and an
experiment scenario to be performed on different environments. The experiment
as it stands has been validated through internal and external review and
through application to several environments that support project management.

A Guide to the Assessment of Software Development Methods
Over the past decade, the term "software engineering methods has been attached
to a variety of procedures and techniques that attempt to provide an orderly,
systematic way of developing software. Existing methods approach the task of
software engineering in different ways. Deciding which methods to use to reduce
development costs and improve the quality of products is a difficult task. This
report outlines a five- step process and an organized set of questions that
provide method assessors with a systematic way to improve their understanding
of and form opinions about the ability of existing methods to meet their
organization's needs.

Managing Development of Very Large Systems: Implications for Integrated
Environment Architectures
Version and configuration control are mechanisms for managing source code and
system builds. In the development of very large systems, built by large teams,
development management is the dominant factor. In this paper we examine
management support for development through integrated environments and
investigate the implications for environment architectures. We do so by
defining a project scenario that is to be performed with integrated project
support environments. The scenario has been carefully designed to not only
determine the scope of management functionality provided by a particular
environment, but also to probe implications for the architecture of
environments. The implications discussed in this paper are: focus on user
activities; the integration of project management and development support
concepts; the ability to reinforce and avoid conflict with particular
organizational models; the ability to support evolution and change of the
product, environment, and organization; and the capability for adaptation and
insertion into a work environment. The scenario is part of a methodology for
evaluation of environments currently used at the Software Engineering
Institute.

Evaluation of the Rational Environment
This report presents an analysis of the Rational R1000 Development System for
Ada, also called the Rational Environment. The evaluation combined the use of
the Software Engineering Institute (SEI) methodology for evaluation of Ada
environments, an analysis of functionality not covered by that methodology, and
an assessment of the novel environment architecture of the Rational
Environment. In addition to this report, Experiment Transcripts for the
Evaluation of the Rational Environment, by Grace Downey, Mitchell Bassman, and
Carl Dahlke (CMU/SEI-88-TR-21) contains support material for the experimental
results. The support material is the result of performing experiments based on
the SEI's environment evaluation methodology. It consists of transcripts of
the experiments, the detailed answers to the evaluative questions, and the
detailed performance results.

Kernel Facilities Definition
This document defines the conceptual design of the Kernel by specifying 1) the
underlying models, assumptions, and 2) restrictions that govern the design and
implementation of the Kernel; and the behavioral and performance requirements
to which the Kernel is built. This document is the requirements and top level
design document for the Kernel.

Distributed Ada Real-Time Kernel
This paper addresses two distinct needs of real-time applications:
distribution and hard real-time scheduling mechanisms. Specifically, this
paper rejects both the notion of modifying the Ada language to achieve needed
real-time solutions and the current fad of extensively modifying the Ada
compiler and/or vendor-supplied runtime system. Instead, this paper defines
the functionality of a Distributed Ada Real-time kernel (hereafter called the
Kernel). The goal of the Kernel is to support effectively the execution of
distributed, real-time Ada applications in an embedded computer environment by
returning control to the user, where it belongs

The Durra Runtime Environment
Durra is a language designed to support PMS-level programming. PMS stands for
Processor-Memory-Switch, the name of the highest level in the hierarchy of
digital systems. An application or PMS-level program is written in Durra as a
set of task descriptions and type declarations that prescribes a way to manage
the resources of a heterogeneous machine network. The application describes
the tasks to be instantiated and executed as concurrent processes, the types of
data to be exchanged by the processes, and the intermediate queues required to
store the data as they move from producer to consumer processes.
This report describes the Durra Runtime Environment. The environment consists
of three active components: the application tasks, the Durra server, and the
Durra scheduler. After compiling the type declarations, the component task
descriptions, and the application description, the application can be executed
by starting an instance of the server on each processor, starting an instance
of the scheduler on one of the processors, and downloading the component task
implementations (i.e., the programs) to the processors. The scheduler receives
as an argument the name of the file containing the scheduler program generated
by the compilation of the application description. This step initiates the
execution of the application.

Generalized Image Library: A Durra Application Example
Durra is a language designed to support the construction of distributed
applications using concurrent, coarse-grain tasks running on networks of
heterogeneous processors. An application written in Durra describes the tasks
to be instantiated and executed as concurrent processes, the types of data to
be exchanged by the processes, and the intermediate queues required to store
the data as they move from producer to consumer processes.
This report describes an experiment in writing task descriptions and type
declarations for a subset of the Generalized Image Library, a collection of
utilities developed at the Department of Computer Science at Carnegie Mellon
University. The experiment illustrates the development of a typical Durra
application. This is a three step process: first, a collection of tasks
(programs) is designed and implemented (these are the GIL programs); second, a
collection of task descriptions corresponding to the task implementations is
written in Durra, compiled, and stored in a library; and finally, an
application description is written in Durra and compiled, resulting in a set of
resource allocation and scheduling commands to be interpreted at runtime. A
few sample application descriptions were developed as part of the experiment
and are also reported in this document.

MasterTask: The Durra Task Emulator
Durra is a language designed to support the construction of distributed
applications using concurrent, coarse-grain tasks running on networks of
heterogeneous processors. An application written in Durra describes the tasks
to be instantiated and executed as concurrent processes, the types of data to
be exchanged by the processes, and the intermediate queues required to store
the data as they move from producer to consumer processes.
The tasks and types available to an application developer are described by a
collection of Durra task descriptions and type declarations stored in a
library. One of the components of a task description is a specification of the
external timing behavior of the task. It describes the sequence of input and
output port operations and the amount of processing time spent between port
operations.
This report describes MasterTask, a program that can emulate any task in an
application by interpreting the timing expression describing the behavior of
the task, performing the input and output port operations in the proper
sequence and at the proper time.
MasterTask is useful to both application developers and task developers.
Application developers can build early prototypes of an application by using
MasterTask as a substitute for task implementations that have yet to be
written. Task developers can experiment with and evaluate proposed changes in
task behavior or performance by rewriting and reinterpreting the corresponding
timing expression.
