IBM was the first major company to embrace the open-source movement, and it has continued to take a leadership role. IBM Research not only has contributed substantial bodies of code to open-source efforts, but it has initiated many ongoing open-source projects, including Postfix secure e-mail software, the Jikes Java™ source to bytecode compiler, Common Optimization Interface for Operations Research (COIN), and the OpenDX data visualization and analysis system, to cite just four examples. We continue to invest significantly in open-source projects, including both Linux® and Apache. Indeed, both of those have been incorporated into IBM's products.

IBM Research is a major force behind the corporation's open-source activity. Not only do we use open-source software to support our research activities, but open source helps us share research results effectively with our industrial and academic colleagues - by providing the research tools and results on which they can build and expand. A good example of this is the DAISY architectural simulator and associated tools, which aims to represent computer architecture as a layer of software through just-in-time binary-to-binary compilation and a specially designed processor.

Similarly, IBM researchers are able to use and to incorporate into our own efforts results from our external peers. The ability to use software licensed as open source as an adjunct to our own code has allowed us to concentrate on areas wherein we can add the most value and innovation.
