Researchers from several universities, national laboratories, software companies, and government funding agencies participated in the 1998 Scientific Integrated Development Environments for Knowledge, Information, and Computing Workshop. This meeting summarized the state-of-the-art in the area of problem-solving environments (PSEs) for scientific and engineering computation, and mapped out directions for future research. This report presents some of the results from the meeting and recommends promising areas for further work. It describes the need for PSEs, lists characteristics that many PSEs share and lists a few current systems. Design goals and future directions, with an emphasis on research issues, are outlined, followed by summary findings and conclusions.
