摘要:

同时多线程(SMT)能在同一时钟周期执行不同线程的指令,同时开发了指令级并行(ILP)和线程级并行(TLP)。显式并行指令计算(EPIC)关注于编译器和硬件的相互协作。在本文中,我们设计和实现了一套并行环境,其中包括并行编译器OpenUH和基于IA-64的同时多线程体系结构EDSMT,并通过NAS并行测试程序作出了性能评测。

关键词: 同时多线程 显式并行指令计算 OpenUH 并行

Abstract:

Simultaneous multithreading (SMT) processors execute instructions from different threads in the same cycle, which has the unique ability to exploit    ILP and TLP simultaneously. EPIC emphasizes the importance of the synergy between the compiler and the hardware. In this paper, we present our efforts t o design and implement a parallel environment, which includes a parallel compiler OpenUH and the SMT architecture EDSMT based on IA-64. The performance is evaluated using the NAS parallel benchmarks.

Key words: SMT, EPIC, OpenUH, parallel
