IBM  AND THE Open Source Community Deliver new ENTERPRISE CAPABILITIES TO
Linux

Technologies Help Speed Linux Adoption

ARMONK, NY -- June 28, 2001 -- IBM (NYSE:IBM) today announced the
availability of a series of Linux technologies developed in conjunction
with the open source community to enhance the enterprise capabilities of
Linux.  Today's announcement will further enable Linux for mainstream
business uses.

To speed the development of Linux, IBM, as an active participant in the open
source community, is announcing the following technologies:

?    Version 1.0 availability of its Journaled File System (JFS) for Linux --
a high-performance file system that provides rapid recovery from a system
power outage or crash and the ability to support extremely large disk
configurations.
This file system is based on proven file system technology from IBM and has
been open sourced under the GNU General Public License (GPL).  The code is
available at http://oss.software.ibm.com/jfs.  
JFS was initially open sourced in January of 2000, and has had more than 30
code releases since then.

?    Version 1.0 availability of Next Generation POSIX Threading (NGPT) --this
POSIX threading package for Linux improves the scalability of multi-threaded
enterprise applications.  The NGPT will also enhance user application
portability by making Linux conform with industry standards for threading.
The code was derived from the existing GNU Pth and has been open sourced
under the LGPL.  The code is available at
http://oss.software.ibm.com/developerworks/opensource/pthreads.  NGPT was
initially open sourced in January of 2001.

The availability of Version 1.0 of these technologies signifies that they are
now ready for customer use.

Adding to its numerous open source projects, IBM today is also announcing its
participation on a project in conjunction with SGI and Open Source Development
Lab, focusing on enabling enterprise test and verification processes,
methodologies and tooling for the Linux platform:

?    Linux Test Project -- a project for the discussion, development and
posting of open source test suites;  an associated test harness will also
help Linux distributors and enterprise customers stress test Linux. IBM is
currently working with SGI and the Open Source Development Lab (OSDL) to
open source the first test suite focusing on customer enterprise workloads.
The project resides at 
http://sourceforge.net/projects/ltp.

"IBM is working side-by-side the Open Source community to improve Linux and to
add the necessary enterprise capabilities that will support the e-business
functions demanded by today's companies," said Dr. Daniel Frye, Director, IBM
Linux Technology Center. "With the availability for customers of JFS and NGPT,
we are getting one step closer to making Linux enterprise ready."

IBM has been working with the open source community since 1998.  A list of
IBM's technical contributions can be found at the Linux Technology Center
