CoreTool: Identificação e Análise de Threads em Sistemas Multicore
Abstract
The availability of processing resources in current processors platforms along with the increase of software complexity reinforce the demands for tools on monitoring multithreaded applications. This paper presents CoreTool, a tool for threads behavior analysis in multicore systems. CoreTool monitors threads scheduling and execution providing useful information on cores utilization and threads load balancing (instructions per thread, threads scheduling on cores). CoreTool has been built on the top of the Pin dynamic binary instrumentation framework targeted to multithreaded applications. We have performed a set of experiments using Linux applications and programs from the Splash-2 benchmark. Our experiments were carried out on configurations of multicore processors with four (2 physical and 2 virtual) and eight (4 physical and 4 virtual) cores.References
