Abstract： RISC-Ⅴ has been obtained huge attentions and extensively invested over the past decade due to its exciting slogan that “Instruction Sets Want to be Free”. Based on RISC-Ⅴ, we are able to build a “human community with a shared future” in the CPU chip area, although thereare still many challenges. China should explore its capability to make more contributions in building the open-source chip ecosystem.

Abstract： With the rapid development of Internet technologies, the main applications of high performance computing (HPC) are changing form scientific and engineering applications to those focusing on data processing. This situation poses grave challenges for traditional high performance computing architecture, thus high throughput computing (HTC) comes into being. This paper explains the difference between HPC and HTC according to the application features, as well as introduces the basic theory and key technologies of HTC. We also show the research results of HTC chips and systems. Through the breakthrough of above HTC key technologies, it is expected to relieve the bottleneck of core chips, and make due contribution to the China’s new high performance platform in the era of intelligent Internet of Things (IoT).

Abstract： Open source has become an essential innovation model for global technological progress and the construction of an open source innovation system is an important path for China to achieve self-reliance and self-improvement in science and technology. As an indispensable part of the global software value chain and high-tech industry chain, China needs to improve its open source innovation ecosystem. The paper, based on a systematic review of the related development policies and successful experiences on the open source work in US and Europe, puts forward a series of policy suggestions to solve the practical problems faced by the construction of open source ecosystem and promote the construction of an open source innovation system in China.

Abstract： China leaders have been always emphasizing both openness and self-reliance over the past decades. However, it is challenging for institutes and researchers to properly deal with the two requirements which are considered to be unachievable at the same time. In this study, we propose four openness modes as well as two principles for handling openness and self-reliance in the development of science and technology. This paper presents the case study on how Chinese computer pioneers made strategical decisions on the openness and self-reliance in the very early age of Chinese computer history. We also retrospect the practice of openness in the history of the development of science and technology in China. Finally, we discuss the feasibility of adopting the open#2;source mode to achieve both openness and self-reliance in the processor area.

Abstract：内存行为分析是进行内存系统调度、体系结构及应用访存性能等优化的基础，而细粒度的内存行为 分析能够标识内存系统性能瓶颈的源头，并为优化提供丰富的语义信息。常用的内存行为分析手段包括插 桩、模拟器、硬件计数器等，但它们分别存在开销大，准确性不足，无法提供详细信息等问题。本文提出 了一种软硬件混合的细粒度内存行为分析方法，能够对程序的完整访存序列进行函数级和对象级分析。硬 件方面使用HMTT 卡监控系统访存请求，软件方面采用二进制插桩方式来获取函数入口、出口信息，通过 导出内核页表及对象内存分配信息来得到每个对象的内存空间信息。实验结果表明，本文提出的方法能够 以较低的开销，准确地获取真实系统上的函数及对象级的访存序列。
