A parallel computing project may be any research endeavor related to some aspect of parallel programming. Research that uses parallel computers to accomplish its goals (that is, research in another scientific field that involves running simulations or using visualization software) is found elsewhere in the directory (somewhere in Science hierarchy, in the specific category that seems most related to the subject of the research). Many of these projects are new and interesting ways of making parallel computers; others relate to parallel algorithms.
Many institutes have lots of research projects. Listings of research institutes that have a significant computer science bent (many of which have divisions that do scalable programming research) are in Computers/Computer_Science/Research_Institutes.
