Software Environments and Scalable High Level Data Structure Extensions of Fortran for Irregular Loosely Synchronous Problems on SIMD and MIMD Parallel Computers

这项工作将由莱斯大学、锡拉丘兹大学和马里兰大学合作开展。它将研究和开发一些概念，将Fortran D扩展到不规则的、松散同步的问题。Fortran D是Fortran 77和Fortran 90的扩展，它允许程序员指定数据的分布，这是分布式内存机器上并行化的关键步骤，已经在Rice和Syracuse开发出来了。该研究包括四个主要组成部分：(1)扩展Fortran D以适应更广泛的不规则问题，并使使用自动数据映射策略成为可能。(2)高级数据结构的研究，包括数据树、同步问题。(3)不规则映射算法的发展及其在PARTI库中的实现。(4)将不规则映射策略集成到Rice和Syracuse正在开发的Fortran D编译器中

The work to be supported will be a collaboration between Rice University, Syracuse University and the University of Maryland. It will investigate and develop concepts that will extend Fortran D to irregular, loosely-synchronous problems. Fortran D, extensions of Fortran 77 and Fortran 90 that permit the programmer to specify the distribution of data, a key step in parallelization on distributed memory machines, has already been developed at Rice and Syracuse. The research includes four major components: (1) Extending Fortran D to accommodate a wider class of irregular problems and to make it possible to use automatic data mapping strategies. (2) Investigation of high level data structures, including data trees, synchronous problems. (3) Development of irregular mapping algorithms and their implementation in the PARTI library. (4) Integration of the irregular mapping strategies into the Fortran D compiler under development at Rice and Syracuse
