With the proliferation of broadband and wireless networks, we are entering an era in which many computing systems are network connected. Network-optimized computing provides a key technology and requires the optimization of all computational infrastructure resources—such as servers, storage devices, interconnection fabric, routers, and appliances, and their corresponding software stacks—to achieve optimum cost, power, utilization, and management of the workload. Topics for this diverse issue range from applications of network-optimized computing systems and exploitation of heterogeneous multicore-processor systems to an introduction to the IBM wire-speed processor.

Software is strategically central to all businesses today, so businesses must understand, measure, and manage the value provided by software development and delivery. They must also know the risks involved in developing software. This issue contains five papers on the topics of project portfolio management, team practices, software development processes, and risk identification and management. There are also three non-topical papers. The first is on enterprise data management in financial markets. The second describes improved data-detection techniques for tape storage. And the last paper provides a survey of hardware designs for decimal arithmetic in computing systems.

Since the first publication of the IBM Journal of Research and Development in 1957 and the IBM Systems Journal in 1962, these Journals have provided descriptions and chronicles of many important advances in information technology and related topics ranging from atoms to business solutions. To celebrate the 50th anniversary of the IBM Journals, this report highlights a selection of significant papers published in the Journals, along with brief commentaries. The Journal editors chose papers which were very highly cited in the technical literature, described technologies of historic significance, or provided an important overview of a field.
