A parallel language and its programming system for heterogeneous networks

Abstract

The paper presents a new parallel language, mpC, designed specially for programming high-performance computations on heterogeneous networks of computers, as well as its supportive programming environment. The main idea underlying mpC is that an mpC application explicitly defines an abstract network and distributes data, computations and communications over the network. The mpC programming environment uses at run time this information as well as information about any real executing network in order to map the application to the real network in such a way that ensures efficient execution of the application on this real network. Experience of using mpC for solving both regular and irregular real-life problems on networks of heterogeneous computers is also presented.

An approach to the development of debuggers that use semantics of constructs of parallel programs

“…The above-discussed approaches to the organization of the user interface and the step-by-step program execution have been implemented in the debugger included in the integrated development environment (IDE) mpC Workshop [8,9], which is designed for the development of parallel programs in the mpC language [10,11].…”

“…Using the experience accumulated in the development of the parallel programming environment mpC Workshop [8,9], which includes an interactive debugger for parallel programs in mpC [10,11], we suggest a new approach to the design of interactive debuggers for parallel applications.…”
