A Graphical Tool for Performance Analysis of Multicore Systems Based on the Roofline Model
A tool to characterize the performance of parallel codes on multicore systems is presented in this paper. This tool allows the user to define the Roofline Model of the target system, to execute the code under study and to represent the performance results in the roofline plot. The final product is an easy to use tool to provide an insightful model which allows to determine, at a glance, performance issues like load balance, locality and those related to thread and memory allocation. Results show that this model provides practical information of the effects that degrade the performance of a code and gives hints to improve it.
