Yew Sophisticated performance measurement and simulation tools developed on the Cedar multiprocessor system during the last four years are being used to study several key architectural and compiler issues that can enhance the performance of scalable shared memory multiprocessors. These issues include memory latency reduction and hiding strategies, data synchronization requirements for loop-level parallelism, and hierarchical network design. The study of these issues involves the hardware-assisted collection of empirical data on Cedar and the use of simulation. The information thus obtained could lead to the design of next- generation systems that, compared to present-day systems, provide higher sustained performance across a broader range of applications.

Yew 过去四年在 Cedar 多处理器系统上开发的复杂性能测量和模拟工具被用来研究几个关键的架构和编译器问题，这些问题可以增强可扩展共享内存多处理器的性能。这些问题包括内存延迟减少和隐藏策略、循环级并行性的数据同步要求以及分层网络设计。 这些问题的研究涉及硬件辅助收集 Cedar 的经验数据以及模拟的使用。 由此获得的信息可以用于下一代系统的设计，与当今的系统相比，该系统可以在更广泛的应用中提供更高的持续性能。
