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.
