  • About the Edition

    Automatic Performance Prediction of Parallel Programs presents a unified approach to the problem of automatically estimating the performance of parallel computer programs. The author focuses primarily on distributed memory multiprocessor systems, although large portions of the analysis can be applied to shared memory architectures as well. The author introduces a novel and very practical approach for predicting some of the most important performance parameters of parallel programs, including work distribution, number of transfers, amount of data transferred, network contention, transfer time, computation time and number of cache misses. This approach is based on advanced compiler analysis that carefully examines loop iteration spaces, procedure calls, array subscript expressions, communication patterns, data distributions and optimizing code transformations at the program level; and the most important machine specific parameters including cache characteristics, communication network indices, and benchmark data for computational operations at the machine level. The material has been fully implemented as part of P3T, which is an integrated automatic performance estimator of the Vienna Fortran Compilation System (VFCS), a state-of-the-art parallelizing compiler for Fortran77, Vienna Fortran and a subset of High Performance Fortran (HPF) programs. A large number of experiments using realistic HPF and Vienna Fortran code examples demonstrate highly accurate performance estimates, and the ability of the described performance prediction approach to successfully guide both programmer and compiler in parallelizing and optimizing parallel programs. A graphical user interface is described and displayed that visualizes each program source line together with the corresponding parameter values. P3T uses color-coded performance visualization to immediately identify hot spots in the parallel program. Performance data can be filtered and displayed at various levels of detail. Colors displayed by the graphical user interface are visualized in greyscale. Automatic Performance Prediction of Parallel Programs also includes coverage of fundamental problems of automatic parallelization for distributed memory multicomputers, a description of the basic parallelization strategy and a large variety of optimizing code transformations as included under VFCS.

For this purpose, we have developed a performance mod-eling environment which consists of BigSim simulator [13] for performance prediction of large parallel machines. Charm++ is a machine independent parallel programming system. Programs written using this system will run unchanged on MIMD machines with or without a shared memory. It provides high-level mechanisms and strategies to facilitate the task of developing even highly complex parallel applications.

Most performance debugging and tuning of parallel programs is based on the ``measure-modify'' approach, which is heavily dependent on detailed measurements of programs during execution. This approach is extremely time-consuming and does not lend itself to . Selecting Locking Designs for Parallel Programs, Paul E.

IPS is based on a hierarchical model that presents multiple levels of abstraction along with multiple views of performance data. IPS was designed to bridge the gap between the structure of parallel programs and the structure of performance.

Many parallel applications suffer from latent performance limitations that may prevent them from scaling to larger machine sizes or solving larger problems. Often, such performance bugs manifest themselves only when the code is put into production, a point where remediation can be difficult.

Abstract: Parallel programming is important for performance, and developers need a comprehensive set of strategies and technol\൯gies for tackling it. This tutorial is intended for C++ programmers who want to better grasp how to envision, describe and writ對e efficient parallel algorithms at the single shared-memory node level. The parallelization is work-conserving and the parallel ef- ciency E = 1. If this loop implements parallel sorting, then our analysis shows that it is asymptotically optimal in work and depth [25], and thus exposes maximum par-allelism. In this paper, we will show how to perform this analysis automatically. Example II: Parallel reductions.

Multiple threads engage in synchronization operations and use hardware simultaneously. This results in a complex non-linear dependency between the configuration of a program and its performance.

To better understand this dependency a performance prediction model is by: 1. Predicting the performance of parallel programs. Margalef, E. Luque, Automatic performance evaluation of parallel programs, in: Sixth Euromicro Workshop on PDP, IEEE CS,pp.

Understanding dependency between the configuration of the system and its performance is essential for many applications. However, this remains a challenging task, especially for multithreaded programs. Multiple threads use various locking operations, resulting in the parallel execution of some computations and the sequential execution of others.

Performance prediction of parallel workloads on High Performance Computing (HPC) platforms has several applications. From code optimization to efficient job scheduling, having good estimates of the expected runtime of an application can help developers to know what parts of their programs need special attention, or help.

Using computer simulation to predict performance of parallel programs Alexander Tarvo Brown University Providence, RI, USA [email protected] Abstract — As computer programs are becoming more complex, the number of their configuration options increases as well.

These options must be carefully configured to achieve. For short running parallel programs, there can actually be a decrease in performance compared to a similar serial implementation. The overhead costs associated with setting up the parallel environment, task creation, communications and task termination can comprise a significant portion of the total execution time for short runs.
