Issues in Parallelizing Object-Oriented Programs

摘要

For imperative programs, the following two approaches have prevailed forextracting high performance from parallel machines: Explicit Parallel Programming Application developers are asked to tailor their code for these machines using a parallel programming language and/or a library. Automatic Parallelization: Supercompilers are written which detect and enhance the parallelism present in serial programs and translate them into a form suitable for execution on these machines. In principle, they seem to be suitable for object-oriented (00) programs, too. However, for the proponents of both the approaches novel challenges have emerged. In this paper, we identify those research directions and summarize the proposed solutions.
