The topics of research presented here reflect our view of the broad range of issues we need to address in support of our computing environment. Large-scale Scientific Computations represents one of our newest ventures. The goal is to more closely link expertise in the problem domains (e.g., fluid dynamics) with expertise in sophisticated numerical methods, thus allowing for a broader range of solution strategies to get better answers. Parallel Numerical Algorithms focuses more tightly on the development and analysis of numerical techniques for use in parallel computing situations. Issues here include the solution of extremely large partial differential equations, matrix solution techniques, and Monte Carlo programming techniques. In the area of General Numerical Algorithms we recognize the need for a significant amount of research on numerics without the additional complexity of parallelism. This area includes work on partial differential equations, ordinary differential equations, interpolation, and a variety of statistical analysis. Parallel Systems Software addresses issues related to going from a parallel algorithm to its correct and efficient implementation on a particular system. Distributed Operating Systems and Networks describes our efforts to provide a very flexible environment for users to access a diverse set of machines and services in an efficient and simple manner. Expert Systems Software covers another relatively new and expanding area. We are looking at various ways that knowledge engineering ideas can reduce development time for writing new code systems and improve our control over experimental processes. In the section on General Purpose Software we include several projects that span a wide range of topics. The last section, Technology Information Systems, reports the status of a special effort to provide sophisticated methods for allowing users to access remote information centers.
