摘要：Design of a highly reliable SPARC-V8 processor for space applications requires consideration singleevent effects including single event upsets, single event transients, single event latch-up, as well as cumulative effects such as the total ionizing dose（TID）. In this paper, the fault tolerance of the SPARC-V8 processor to radiation effects is discussed in detail. The SPARC-V8 processor, fabricated in the 65 nm CMOS process, achieves a frequency of 300 MHz with a core area of 9.78 9.78 mm^2, and it is demonstrated that its radiation hardened performance is suitable for operating in a space environment through the key elements＇ experiments, which show TID resistance to 300 krad（Si）, SEL immunity to greater than 92.5 Me V cm^2/mg, and an SEU error rate of 2.51 10^-4 per day.

摘要：The ever-increasing need for high performance in scientific computation and engineering applications will push high-perfornlance computing beyond the exascale. As an integral part of a supercomputing system, high- performance processors and their architecture designs are crucial in improving system performance. In this paper, three architecture design goals for high-performance processors beyond the *** are introduced, including effective performance scaling, efficient resource utilization, and adaptation to diverse applications. Then a high-performance many-core processor architecture with scalar processing and application-specific acceleration （Massa） is proposed, which aims to achieve the above three goals by employing the techniques of distributed computational resources and application-customized hardware. Finally, some future research directions regarding the Massa architecture are discussed.

摘要：Modern high-level programming languages often contain constructs whose semantics are non-trivial. In practice however, software developers generally restrict the use of such constructs to settings in which their semantics is simple (programmers use language constructs in ways they understand and can reason about). As a result, when developing tools for analyzing and manipulating software, a disproportionate amount of effort ends up being spent developing capabilities needed to analyze constructs in settings that are infrequently used. This paper takes the position that such distinctions between theory and practice are an important measure of the analyzability of a language.
