Abstract
Numerous studies have shown that Operating System (OS) noise is one of the reasons for significant performance degradation in clustered architectures. Although many studies examine the OS noise for High Performance Computing (HPC), especially in multi-processor/core systems, most of them focus on 2- or 4-core systems. In this paper, we analyze the major sources of OS noise on a massive multithreading processor, the Sun UltraSPARC T1, running Linux and Solaris. Since a real system is too complex ...
