Large core counts and complex cache hierarchies are increasing the burden placed on
commonly used simulation and modeling techniques. Although analytical models provide …

When planning routes, drivers usually consider a multitude of different travel costs, eg,
distances, travel times, and fuel consumption. Different drivers may choose different routes …

Power dissipation is increasingly important in CPUs ranging from those intended for mobile
use, all the way up to high-performance processors for high-end servers. While the bulk of …

Modern Java programs, such as middleware and application servers, include many complex
software components. Improving the performance of these Java applications requires a …

This article describes the Digital Continuous Profiling Infrastructure, a sampling-based
profiling system designed to run continuously on production systems. The system supports …

We propose a low overhead, online memory monitoring scheme utilizing a set of novel
hardware counters. The counters indicate the marginal gain in cache hits as the size of the …

In the past decade, the exponential growth in commodity CPU's speed has far outpaced
advances in memory latency. A second trend is that CPU performance advances are not …

A common way of representing processor performance is to use Cycles per Instruction
(CPI)stacks' which break performance into a baseline CPI plus a number of individual miss …

This paper presents the design, implementation, and application of ParaProf, a portable,
extensible, and scalable tool for parallel performance profile analysis. ParaProf attempts to …

An accurate, tractable, analytic cache model for time-shared systems is presented, which
estimates the overall cache miss-rate of a multiprocessing system with any cache size and …
