Design and Implementation of a General Purpose Parallel Programming System

چکیده
In scientific computing, the use of parallelism has led to widespread improvements in the performance of complex computations. However, there are many non-scientific general purpose applications that could also benefit from the modest use of parallelism. The users of these applications generally work in offices possessing large networks of PCs. If programmers could only write programs that could distribute computation through the idle machines on this network, then the users could reap significant performance benefits. But due to the lack of good programming support tools, general purpose applications are unable to make use of this kind of parallel computation. In this paper, we present a model for general purpose parallel computation called the Composite Model, and its implementation as a set of portable language extensions. We then present an example of a language extended with composite constructs. Finally, we describe the compiler technology that allows composite programs to run effectively on workstation clusters.

This paper studies the parallel machine scheduling problem subject to machine and job deterioration in a batched delivery system. By the machine deterioration effect, we mean that each machine deteriorates over time, at a different rate. Moreover, job processing times are increasing functions of their starting times and follow a simple linear deterioration. The objective functions are minimizin...
