Choosing Representative Slices of Program Execution for Microarchitecture Simulations: a Preliminary Application to the Data Stream Choosing Representative Slices of Program Execution for Microarchitecture Simulations: a Preliminary Application to the Data Stream

چکیده
Microarchitecture simulations are aimed at providing results representative of the behavior of a processor running an application. Due to CPU time constaints, only a few execution slices of a large application can be simulated. The aim of this paper is to propose a technique to choose a few program execution slices representative of the entire execution. We characterize the behavior of each consecutive slice executed. Then we use a statistical classiication method to discriminate the execution slices and select the representative ones. In this paper, we detail this approach and apply it to the data stream. Using data cache simulations on the SPEC95 programs, we show that slices representing 1.46 % (average upon all the SPEC95 but one) of the overall program activity are as representative as trace sampling using a 10 % sampling ratio.

Proposing an Efficient Software-Based Method for Enhancing the Reliability of Critical Application Robot
Robots play such remarkable roles in humans’ modern lives that performing many tasks without them isimpossible. Using robotic systems is gradually increasing the tasks allocated to them and they are becomingmore complex and critical. Software reliability is one of the most significant requirements of robots. Forenhancing reliability, systems should be inherently designed to be tolerable of soft...
متن کاملChoosing the Best Hierarchical Clustering Technique Based on Principal Components Analysis for Suspended Sediment Load Estimation
1- INTRODUCTION The assessment of watershed sediment load is necessary for controling soil erosion and reducing the potential of sediment production. Different estimates of sediment amounts along with the lack of long-term measurements limits the accessibility to reliable data series of erosion rate and sediment yield. Therefore, the observed data of suspended sediment load could be used to ...
متن کاملPerformance Analysis and Optimization of the OP2 Framework on Many-Core Architectures
This paper presents a benchmarking, performance analysis and optimization study of the OP2 ‘active’ library, which provides an abstraction framework for the parallel execution of unstructured mesh applications. OP2 aims to decouple the scientific specification of the application from its parallel implementation, and thereby achieve code longevity and near-optimal performance through re-targetin...
