IBM DELIVERS MORE PC POWER WITH OS/2 FOR SYMMETRICAL MULTIPROCESSING

NEW YORK, June 28, 1994...IBM today introduced OS/2 for Symmetrical
Multiprocessing Version 2.11 a new member of its award-winning 32-bit PC
operating system family. OS/2 for SMP provides performance and
client/server benefits to users of Intel 486 and Pentium multiprocessor
systems while protecting their software investments in applications.

OS/2 for SMP offers all the features of OS/2 2.11 and increases performance
by distributing application processes or threads among processors to
optimize the capabilities of a multiprocessor computer.

Industry Standard, Supported by OEMs

OS/2 for SMP will be available this summer. Several computer vendors
announced support today for OS/2 for SMP, including Advanced Logic
Research, AST Research, Compaq Computer Corp. Hewlett-Packard Co., IBM,
Intel, Tricord Systems, VTech, and Wyse Technology. OS/2 for SMP will also
be available on future IBM PC-based multiprocessing servers. OS/2 for SMP
is consistent with the industry standard Multiprocessor Specification
Version 1.1, which means that multiprocessor computers built on this
specification can run OS/2 for SMP without changes to the BIOS, operating
system or hardware interfaces.

OS/2 for SMP features transparent support of systems with two or more CPUs,
increasing raw computing power with a lower memory requirement than any
other SMP operating system available today.

For multiprocessing-enabled applications, customers will see substantial
performance gains with each new processor added to their systems. OS/2 for
SMP can support up to 16 processors on a single system. Cost-conscious
organizations that want to expand their network resources can reconfigure
server systems to handle larger and larger networks, or consolidate the
functions of their uniprocessor servers on a single multiprocessor system
running OS/2 for SMP.

"OS/2 for SMP optimizes Intel-based hardware for enterprise-wide, scalable,
mission critical applications," said Kevin Dugan, manager of systems
development at the network management center of Cable & Wireless Inc., a
$600 million long-distance telephone company based in Vienna, Va.

"It is absolutely critical for businesses such as ours because we want to
make sure that our systems and software will be able to grow with us as
our business needs grow," continued Dugan. "With OS/2 for SMP's scalable
performance, we can keep the same operating system and applications as we
migrate from desktop workstations to multiprocessor systems. The end
result is a substantial savings for us."

Ideal Technology for Client/Server Environments

Network server and high-end desktop workstation environments will benefit
from OS/2 for SMP's scalable performance. Transaction processing and
relational database applications on servers as well as compute-intensive
applications such as CAD/CAM, forecasting, modeling or simulation programs
on workstations will run faster and more efficiently on OS/2 for SMP. For
example, when OS/2 for SMP and IBM's relational database manager, DB2/2
Version 1.2, are installed on parallel hardware systems, performance and
scalability are significantly improved. Users may expect some query
workloads to scale as high as 1.8 to 1.9 on a dual-processor machine.
Applications such as Lotus 1-2-3 for OS/2 run faster with the new OS/2 for
SMP, which also is supported by networking platforms such as IBM's OS/2
LAN Server 3.01.

"Only OS/2 scales the range of computing power, from small notebooks to
high-end SMP-enabled computers," said Dan Lautenbach, general manager for
IBM's Personal Software Products division. "We've created OS/2 for SMP for
the high-end server market where exceptional performance and mission
critical reliability are important. Whether an organization adds more
microprocessors to its computers or just wants to make the most of its
current multiprocessor system, users will see a quantifiable performance
boost with OS/2 for SMP."

Measurable Performance Gains

OS/2 for SMP intelligently supervises computing operations and allocates
processing resources as necessary, improving processing capabilities.
Application processes or threads are automatically dispatched to run on
any of the available system processors. The end result is enhanced
performance through a load-balanced system.

Users can run multiple DOS, Windows and OS/2 2.1 applications concurrently
on a single system and benefit from performance gains. OS/2 for SMP is
compatible with existing OS/2 and DOS/Windows applications. Even
single-tasking DOS applications benefit, because OS/2's heavy use of
threads allows overlap of systems services and application execution.
Because multiple processors are dispatched, multiple DOS/Windows virtual
machines can run faster with no modification. Native OS/2 applications
will exploit OS/2's multithreading capabilities, providing even higher
performance gains. In addition, OS/2 for SMP supports applications
designed for uniprocessor computers.

Power and Performance Available This Summer

OS/2 for SMP will be available this summer. It will be supported on
hardware from Advanced Logic Research, AST Research, Compaq Computer
Corp., Hewlett-Packard Co., IBM, Tricord Systems, VTech, and Wyse
Technology. It is initially available in a U.S. English version only. For
customers with a supported SMP-enabled computer, OS/2 for SMP can be
ordered in July by calling 800-3IBM-OS2, (800-342-6672), in the U.S. or
through local dealers and distributors in other countries. Suggested
retail prices are: $395 for the 1-2 processor version, $595 for the 1-7
processor version, and $795 for the 1-16 processor version.
