Single processing units have now reached a point where further major improvements in their performance are restricted by their physical limitations. This is causing a slowing down in advances at the same time as new scientific challenges are demanding exascale speed. This has meant that parallel processing has become key to High Performance Computing (HPC).This book contains the proceedings of the 14th biennial ParCo conference, ParCo2011, held in Ghent, Belgium. The ParCo conferences have traditionally concentrated on three main themes: Algorithms, Architectures and Applications. Nowadays though, the focus has shifted from traditional multiprocessor topologies to heterogeneous and manycores, incorporating standard CPUs, GPUs (Graphics Processing Units) and FPGAs (Field Programmable Gate Arrays). These platforms are, at a higher abstraction level, integrated in clusters, grids and clouds. The papers presented here reflect this change of focus. New architectures, programming tools and techniques are also explored, and the need for exascale hardware and software was also discussed in the industrial session of the conference.This book will be of interest to all those interested in parallel computing today, and progress towards the exascale computing of tomorrow.

As predicted by Gordon E. Moore in 1965, the performance of computer processors increased at an exponential rate. Nevertheless, the increases in computing speeds of single processor machines were eventually curtailed by physical constraints. This led to the development of parallel computing, and whilst progress has been made in this field, the complexities of parallel algorithm design, the deficiencies of the available software development tools and the complexity of scheduling tasks over thousands and even millions of processing nodes represent a major challenge to the construction and use of more powerful parallel systems. This book presents the proceedings of the biennial International Conference on Parallel Computing (ParCo2015), held in Edinburgh, Scotland, in September 2015. Topics covered include computer architecture and performance, programming models and methods, as well as applications. The book also includes two invited talks and a number of mini-symposia. Exascale computing holds enormous promise in terms of increasing scientific knowledge acquisition and thus contributing to the future well-being and prosperity of mankind. A number of innovative approaches to the development and use of future high-performance and high-throughput systems are to be found in this book, which will be of interest to all those whose work involves the handling and processing of large amounts of data.

The field of High Performance Computing (HPC) is characterized by the contin-uous evolution of computing architectures, the proliferation of computing resourcesand the increasing complexity of applications users wish to solve. One of the mostimportant software of the HPC stack is the Resource and Job Management System(RJMS) which stands between the user workloads and the platform, the applica-tions and the resources. This specialized software provides functions for building,submitting, scheduling and monitoring jobs in a dynamic and complex computingenvironment.In order to reach exaflops HPC systems, new constraints and objectives havebeen introduced. This thesis develops and tests the idea that the users of suchsystems can help reaching the exaflopic scale. Specifically, we show and introducenew techniques that employ users behaviors to improve energy consumption andoverall cluster performances.To test the proposed techniques, we need to develop new tools and method-ologies that scale up to large HPC clusters. Thus, we designed adequate tools thatassess new RJMS scheduling algorithms of such large systems. These tools areable to run on small clusters by emulating or simulating bigger platforms. Afterevaluating different techniques to measure the energy consumption of HPC clusters,we propose a new heuristic, based on the popular Easy Backfilling algorithm, inorder to control the power consumption of such huge systems. We also demonstrate,using the same idea, how to control the energy consumption during a time period.The proposed mechanism is able to limit the energy consumption while keepingsatisfying performances. If energy is a limited resource, it has to be shared fairly.We also present a mechanism which shares energy consumption among users. Weargue that sharing fairly the energy among users should motivate them to reducethe energy consumption of their applications. Finally, we analyze past and presentbehaviors of users using learning algorithms in order to improve the performancesof the parallel platforms. This approach does not only outperform state of the artmethods, it also shows promising insight on how such method can improve otheraspects of RJMS.
