Programming supercomputers is currently difficult and time consuming. Scientists and engineers who use these machines have an urgent need for a programming environment that is portable, interactive, flexible, and convenient. There is a prototype that serves as an existence proof for the feasibility of constructing a useful environment for scientific computing. This software tool, called CLAMth (the Computatinal Linear Algebra Machine), currently exists as a prototype version written in Fortran 77. Although CLAM is successful, we view it as a "first generation" programming environment for supercomputers. Using a modern programming language (T), we propose to build a "second generation" environment that will: oAccept the programmer's preferred language, be it T, CLAM, or Fortran. oHave an interpretive debugger that will promote fast prototyping. oBe fully portable from workstation to mainframe to supercomputer. oUtilize state-of-the-art algorithms for large scale numerical analysis tasks. It will handle vector and matrix data structures automatically and also contain an "expert" capability to select appropriate algorithms from its own internal library to match the solution techniques to the problem size and characteristics. In short, this environment will provide the applications- oriented engineer or scientists with the fastest possible solution for any particular computation, without requiring the user to make decisions about the appropriate algorithms and data structures to be employed. ---------------------------------------------------------------- This proposal focuses on the development of programming tools for scientists and engineers. Specifically the proposal refines the programming language associated with CLAM, a previously developed software package, for improved programming environments. This new version of CLAM will have several improvements such a portability, automatic parallelization, etc. and can be easily incorporated into code generated by other languages. Thus 36 month proposal will be funded all at one time as follows: $150.0k CSE (CISE) $ 50.0k Comp. Math (DMS) $ 50.0k New Tech (DASC) --------- $250.0k 36 mos. paid entirely in first year. ***

编程超级计算机目前是困难和时间 消耗。 使用这些机器的科学家和工程师 迫切需要一种可移植的编程环境， 交互式、灵活、方便。 有一个原型， 作为构建的可行性的存在性证明 科学计算的有用环境。 这个软件 一个叫做CLAMth（ComputatinalLinearAlgebraMachine）的工具， 目前存在的一个原型版本写在Fortran 77。 虽然CLAM是成功的，但我们认为它是“第一代”， 超级计算机的编程环境 使用现代 编程语言（T），我们建议建立一个“第二个 “新一代”环境将： o接受程序员的首选语言，无论是T，CLAM， 或者Fortran。 o有一个解释性的调试器，将促进快速 原型设计 o从工作站到大型机完全可移植， 超级计算机 o利用最先进的算法进行大规模 数值分析任务。 它将处理矢量和矩阵数据 结构，还包含“专家”功能 从自己的内部库中选择适当的算法， 将解决方法与问题的规模相匹配， 特色 简而言之，这个环境将提供应用程序- 面向工程师或科学家以最快的速度 任何特定计算的解决方案，而不需要 用户对适当的算法和数据做出决定 要使用的结构。 ---------------------------------------------------------------- 这项建议的重点是拟订方案 科学家和工程师的工具。 具体来说， 改进了与CLAM相关的编程语言， 以前开发的软件包，用于改进编程 环境. 这个新版本的CLAM将有几个 诸如可移植性、自动并行化等的改进。 并且可以容易地并入到由其他系统生成的代码中。 语言 因此，36个月的提案将一次性全部获得资金 时间如下： $150.0k CSE（CISE） 5万美元Comp. Math（DMS） 5万美元新技术（DASC） --------- $250.0k 36个月第一年全部付清。 ***
