A Language and Programming Environment for High-Performance Parallel Computing on Heterogeneous Networks

Abstract--An mpC language designed specifically for programming high-performance computations onhet-erogeneous networks i described. An mpC program explicitly defines an abstract omputing network and dis-tributes data, computations, and communications over it. At runtime, the mpC programming environment uses this information and that about the actual network to distribute the processes over the actual network so as to execute the program in the most efficient way. Experience inusing mpC for solving problems on local networks consisting of heterogeneous workstations is discussed. 1
