CSR: Small: Safe Parallelization in a Dynamic Language

多核处理器的普及产生了在所有编程语言中支持并行处理的需求。然而，脚本语言的动态特性使得在这些语言中支持正确的并行编程变得特别困难。最近的研究通过推测程序并行化实现了安全的并行编程。这个项目扩展了这些技术，以支持Ruby语言中的并行编程。这项工作主要集中在三个方面：解释器、核心语言库和垃圾收集器。通过在Ruby上的实验，本研究有助于理解动态语言遇到动态并行化时的一般协同作用和限制。由此产生的并行Ruby实现是一种非编程专家也可以使用的通用并行语言。由于其易于使用，它有望在并行编程应用程序的快速原型设计和跨所有科学学科的并行编程教学中非常有用。这种技术的转移是通过在Web上发布开源代码来实现的。与该项目相关的外展活动包括与大学预科学生合作，从代表性不足的群体招募学生，以及与行业合作。通过学生参与语言实现，以及在几门课程中使用并行Ruby语言的实验，教育与研究相结合。

Ubiquity of multicore processors has created a demand to support parallel processing in all programming languages. However, the dynamic nature of scripting languages makes supporting correct parallel programming in these languages especially difficult. Recent research has enabled safe parallel programming through speculative program parallelization. This project extends these techniques to support parallel programming in the Ruby language. The work focuses on three areas: the interpreter, the core language libraries, and the garbage collector. Through experimentation on Ruby, the research helps to understand the general synergy and limitations when a dynamic language meets dynamic parallelization.The resulting parallel Ruby implementation is a general-purpose parallel language that can be used by non-programming experts. Because of its ease of use, it is expected to be very useful for rapid prototyping of parallel programming applications and teaching parallel programming across all scientific disciplines. Transfer of this technology is facilitated by open-source distribution of the code on the Web. Outreach activities associated with the project include work with pre-college students, recruitment of students from under-represented groups, and collaboration with industry. Education is integrated with the research through involvement of students in the language implementation, and by experimentation with the use of the parallel Ruby language in several courses.
