Graphics-Oriented Programming Environments for Highly Parallel Computation

对高度并行计算机进行编程是一项极其复杂的任务，需要开发适当的支持工具集，包括面向MIMD的图形编程环境，集成机器。我们已经实现了一个作为多处理器模拟器前端的基本环境。这个环境将作为我们在两个领域研究的试验台：高级语言和并行调试。在高级语言领域，我们研究图形语法的规范，通过基于图形语法的机制提供映射帮助，并为美学图形布局和放置设计启发式。在并行调试领域，我们将确定哪些类型的信息对并行程序的调试最有用。

Programming highly parallel computers is an extremely complex task which will necessitate the development of appropriate sets of support tools, including graphics-oriented programming environments for MIMD, ensemble machines. We have already implemented a rudimentary environment built as the front end to a multiprocessor simulator. This environment will serve as the testbed for our research in two areas: high-level languages and parallel debugging. In the area of high-level languages, we investigate specifications of graph grammar, provide mapping assistance through graph-grammar based mechanisms, and design heuristics for aesthetic graph layout and placement. In the area of parallel debugging, we would determine which kinds of information is most useful to debugging of parallel programs.
