Evaluating Techniques for Parallelization Tuning in MPI, Ompss and MPI/Ompss
Evaluating techniques for parallelization tuning in MPI, OmpSs and MPI/OmpSs Advisors: Author: Prof. Jesús Labarta Vladimir Subotic´ Prof. Mateo Valero Prof. Eduard Ayguade´ A THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF Doctor per la Universitat Politècnica de Catalunya Departament d’Arquitectura de Computadors Barcelona, 2013 i Abstract Parallel programming is used to partition a computational problem among multiple processing units and to define how they interact (communicate and synchronize) in order to guarantee the correct result. The performance that is achieved when executing the parallel program on a parallel architec- ture is usually far from the optimal: computation unbalance and excessive interaction among processing units often cause lost cycles, reducing the efficiency of parallel computation. In this thesis we propose techniques oriented to better exploit parallelism in parallel applications, with especial emphasis in techniques that increase asynchronism. Theoretically, this type of parallelization tuning promises multiple benefits. First, it should mitigate communication and synchro- nization delays, thus increasing the overall performance. Furthermore, parallelization tuning should expose additional parallelism and therefore increase the scalability of execution. Finally, increased asynchronism would allow more flexible communication mechanisms, providing higher toler- ance to slower networks and external noise. In the first part of this thesis, we study the potential for tuning MPI par- allelism. More specifically, we explore automatic techniques to overlap communication and computation. We propose a speculative messaging technique that increases the overlap and requires no changes of the orig- inal MPI application. Our technique automatically identifies the applica- tion’s MPI activity and reinterprets that activity using optimally placed non-blocking MPI requests. -

Intel® VTune™ Amplifier XE The Old Way versus The New Way The Old Way: To see if there is an issue with branch misprediction, multiply event value (86,400,000) by 14 cycles, then divide by CPU_CLK_UNHALTED.THREAD (5,214,000,000). Then compare the resulting value to a threshold. If it is too high, investigate. The New Way: Look at the Branch Mispredict metric, and see if any cells are pink. -
