DMS GETS MAIL GUARD, FIREWALL
Topic: DII
Trusted Information Systems, Inc., has completed work on a Defense
Message System (DMS) version of its Gauntlet firewall. This release,
funded by the National Security Agency under a contract awarded last
spring, is a Fortezza-enabled X.400 mail guard and firewall. The
contractor will augment the release with software upgrades for X.500
directory services next year.
A DISA official said X.500 support is a requirement for DMS firewalls.

ADTEST: A TEST DATA GENERATION SUITE FOR ADA SOFTWARE SYSTEMS
Topic: Ada, Software Engineering
A paper in the August issue of "IEEE Transactions on Software Engineering,"
examines the design of the software system, ADTEST, for generating test
data for programs developed in Ada 83. The key feature of this system
is that the problem of test data generation is treated entirely as a
numerical optimization problem and, as a consequence, this method does
not suffer from difficulties commonly found in symbolic execution systems.
The system has been tested on large Ada programs (60,000 lines of code)
and found to reduce the effort required to test programs as well as
provide an increase in test coverage.

PLANNING EFFICIENT SOFTWARE TESTS
Topic: Software Engineering
Software testing consumes 30%-70% of an organization's software
development resources. However, many faults remain undetected and are
later found in the field. To improve customer satisfaction and reduce
development costs, it is imperative that software teams reduce testing
costs, reduce product introduction delays, and send fewer faults to the
field.
The Robust Testing Method*, based on the special properties of orthogonal
arrays, can achieve these goals by generating test cases that are more
efficient and thorough in finding faults. In many cases, the Robust
Testing method has increased tester productivity by a factor of two or
better.

ULTRASPARC-III MICROPROCESSOR PRODUCTION SET FOR 1998
Topic: COE
Sun Microsystems has announced that it expects to begin sample production
of its next-generation UltraSPARC-III microprocessor by the summer of 1998,
with the first systems emerging six to nine months later -- or sometime
around early 1999.
Gary Lauterbach, chief architect of the UltraSPARC-III, says the chip
will have a clock speed in excess of 600 MHz (Megahertz) and, thanks to a
design that is "focused on scalability," will be able to scale to over
1,000 processors in a single system. He says the new .25 micron
manufacturing process used in the UltraSPARC-III is a "major driver"
behind the performance increases, calling them "a two to three times leap
from the previous generation [the UltraSPARC-II]."
