Efficient, Unified, and Scalable Performance Monitoring for Multiprocessor Operating Systems
Robert W. Wisniewski, Bryan S. Rosenburg · 2003
Programming, understanding, and tuning the performance of large multiprocessor systems is challenging. Experts have difficulty achieving good utilization for applications on large machines. The task of implementing scalable systems such as an operating system or database on large machines is even more challenging. And the importance of achieving good performance on multiprocessor machines is increasing as the number of cores per chip increases and as the size of multiprocessors increases. Crucial to achieving good performance is being able to understand the behavior of the system.
