US-Cameroon Planing Research Visit on Combined Binary Code Translation and Synthesis for Heterogeneous Multiprocessor Systems, January 2014

1346542 Bobda该奖项将为来自阿肯色大学的PI Christophe Bobda博士提供支持，以在2013年12月至2014年1月组织为期10天的规划研究访问，访问位于雅温得的雅温得大学和位于德昌的德昌大学，这两所大学都位于喀麦隆。他将由两名来自阿肯色州大学的学生陪同。这次拟议访问的主要目的是会见雅温得大学的Rene Ndoundam博士和德昌大学的副教授，以制定一项国际研究的总体计划。他们将（1）制定未来在编译器，架构合成和运行时架构优化领域的合作计划，（2）为远程合作建立研究，培训和交流框架，（3）为国际赠款提案的发展奠定基础，以维持这一努力，以及（4）组织研讨会和FPGA实验室，与爱沙尼亚的学生和教师一起，教授他们计算机体系结构和FPGA器件多核设计方面的技术。这个项目将有助于在遗留代码上利用新架构的性能，从而节省重新设计的时间和金钱。由于减少了要配置的元素数量，所提出的粗粒度架构将允许在可配置处理器上快速运行时合成选定的代码块。所提出的粗粒度架构使用直接互连和片上网络元素的组合，以增加设备级的灵活性，同时保持组件边界内的高性能。所提出的基于运行时频谱的综合方法使用的事件的拉普拉斯矩阵的奇异值来计算在一个2D字段中的指令的放置在这样一种方式，使指令之间的总互连成本最小化。最后，建议的通用和可配置的流组件将允许一个透明的管理的数据交换和可重构处理器上执行的代码块之间的同步和那些运行在其余processors.Broader的影响：这个项目的主要成果之一是异构多处理器系统的遗留二进制代码的运行时翻译。这将允许现有程序自动迁移到新的体系结构上，从而提高它们的性能，同时避免完全重新设计和重新编译。规划访问将为建立更广泛的国际合作网络奠定基础，新的合作伙伴可以很容易地融入其中。这一合作努力产生的研究内容将使美国和喀麦隆的本科生和研究生受益。来自阿肯色州大学的两名学生将通过在雅温得大学和德昌大学举办的研讨会上介绍他们的工作来获得国际经验。除了规划访问之外，PI还将积极招募几名本科生研究人员，特别是女性和少数民族，从A大学从事编译器，架构设计和应用程序的工作。科学和工程研究中代表性不足的群体将通过工程职业意识计划（ECAP），阿肯色州路易斯斯托克斯少数民族参与联盟（ARK-LSAMP）和乔治华盛顿卡弗项目的U招募。

1346542BobdaThis award will provide support for PI Dr. Christophe Bobda, from the University of Arkansasto organize a 10 day planning research visit in December 2013-January 2014 to the University of Yaounde in Yaounde and the University of Dschang in Dschang, both in Cameroon. He will be accompanied by two students from the University of Arkansas. The main objective of this proposed trip is to meet with Dr. Rene Ndoundam of the University of Yaounde and associate faculty at the University of Dschang to develop a master plan for international research. They will (1) develop plans for future collaboration in the fields of compilers, architecture synthesis and run-time architecture optimization, (2) put in place a research, training and exchange framework for the remote collaboration, (3) set the basis for the development of international grant proposals to sustain this effort, and (4) organize seminars and FPGA labs with Cameroonian students and faculty to teach them technical aspects in computer architecture and multicore design on FPGA devices.Intellectual Merit: This project will help leverage the performance of new architecture on legacy code, thus saving time and money for redesign. With the reduced amount of elementsto configure, the proposed coarse-grained architecture will allow for a fast run-time synthesisof selected code blocks onto the configurable processor. The proposed coarse-grained architecture uses a combination of direct interconnect and network on chip elements to increase the flexibility at device level, while maintaining high performance within a component boundary. The proposed run-time spectral-based synthesis approach uses the singular values of the Laplacian of the incident instruction-matrix to compute the placement of instructions in a 2D field in such a way that the total interconnect cost among instructions is minimized. Finally, the proposed generic and configurable streaming component will allow for a transparent management of data exchange and synchronization among code blocks executing on the reconfigurable processor and those running on the remaining processors.Broader Impacts: One of the major outcomes of this project is the run-time translation of legacy binary code for heterogeneous multiprocessor systems. This will allow for automatic migration of existing programs onto new architectures, thus improving their performance while avoiding complete redesign and recompilation. The planning visit will lay the groundwork for a broader international collaboration network in which new partners could be easily integrated. The research components produced by this collaborative effort would benefit undergraduate and graduate students in the United States and in Cameroon. The two students from the University of Arkansas will gain international experience by presenting their work at the seminars organized at the University of Yaounde and the University of Dschang. Beyond the planning visit, the PI will actively recruit several undergraduate researchers, especially women and minorities, from the U of A to work on compilers, architecture design and applications. Under-represented groups in science and engineering research will be recruited through the U of A Engineering Career Awareness Program (ECAP), Arkansas Louis Stokes Alliance for Minority Participation (ARK-LSAMP), and the George Washington Carver Project.
