项目摘要

Many scientists, engineers, and students use the programming languages C, C++, and Fortran. Scientists who use these languages to conduct their experiments set up their programs to run in sequence -- what computer scientists call "serial processing." In order to make the best use of the state-of-the-art High Performance Computing (HPC) platforms to run more efficient experiments or to run very large simulations, the programs written in these languages need to be able to run simultaneously, what computer scientists call "in parallel" as distinct from "serial". Enabling the parallelization of the applications and software, however, remains a challenge. This project proposes deployment of an Interactive Parallelization Tool (IPT), which helps scientists, engineers, and students build on their customary use of C/C++/Fortran to create more efficient programs that can run on advanced HPC platforms. The IPT will be made available to the community through a web-portal for convenient code generation and testing on computational resources of the national cyberinfrastructure (CI). The team has developed a prototype IPT to parallelize multiple design patterns written in C/C++ at a high-level of abstraction. The proposed project will harden the IPT prototype into a production-quality tool and will extend support for the efficient parallelization of additional types of C/C++ applications. The team will also prototype the parallelization of Fortran applications. Carefully selected test cases will be provided with the IPT to engage and educate the users about the advantages and disadvantages of the various parallel programming strategies so that they can be appropriately applied in solving real-world problems. The IPT can be extended to support additional parallel programming paradigms, applications classes, and languages. It will be evaluated using code from multiple domains (e.g. biology, geosciences, civil engineering, and astronomy), and potential users will be engaged during the testing phase. This will all be served through a web-based portal, and will enable a low-risk guided approach for researchers, practitioners, and students to incorporate HPC in their work.

许多科学家，工程师和学生使用编程语言C，C ++和Fortran。使用这些语言进行实验的科学家设置了他们的程序以按顺序运行 - 计算机科学家称之为“串行处理”。为了充分利用最先进的高性能计算（HPC）平台来运行更有效的实验或运行非常大的模拟，用这些语言编写的程序需要同时运行，计算机科学家称其为“与“ cernial”不同的“并行”。但是，实现应用程序和软件的并行化仍然是一个挑战。该项目建议部署一种交互式并行化工具（IPT），该工具可以帮助科学家，工程师和学生以惯例使用C/C ++/Fortran来创建可以在高级HPC平台上运行的更有效的程序。 IPT将通过网络门户提供给社区，以实现方便的代码生成和对国家网络基础设施（CI）的计算资源进行测试。该团队开发了一个原型IPT，可以在高级抽象的情况下并行化用C/C ++编写的多种设计模式。拟议的项目将将IPT原型变成生产质量工具，并将扩展对其他类型的C/C ++应用程序有效并行化的支持。该团队还将原型制作Fortran应用程序的并行化。精心选择的测试用例将与IPT一起提供，以吸引和教育用户有关各种并行编程策略的优势和缺点，以便可以适当地应用于解决现实世界中的问题。可以扩展IPT以支持其他并行编程范式，应用程序类和语言。它将使用来自多个领域的代码（例如生物学，地球科学，土木工程和天文学）进行评估，并且在测试阶段将参与潜在用户。这一切都将通过基于Web的门户提供服务，并将为研究人员，从业人员和学生提供低风险的指导方法，以将HPC纳入其工作。
