This book provides recent research results in high-performance computing on complex environments, information on how to efficiently exploit heterogeneous and hierarchical architectures and distributed systems, detailed studies on the impact of applying heterogeneous computing practices to real problems, and applications varying from remote sensing to tomography. Topics include: numerical analysis for heterogeneous and multicore systems; optimization of communication for high performance heterogeneous and hierarchical platforms; efficient exploitation of heterogeneous architectures, hybrid CPU+GPU, and distributed systems; energy awareness in high-performance computing; and applications of heterogeneous high-performance computing. --cEdited summary from book.0 aSeries; Title Page; Copyright; Dedication; Contributors; Preface; Part I: Introduction; Chapter 1: Summary of the Open European Network for High-Performance Computing in Complex Environments; 1.1 Introduction and Vision; 1.2 Scientific Organization; 1.3 Activities of The project; 1.4 Main Outcomes of the Action; 1.5 Contents of The Book; Acknowledgment; Part II: Numerical Analysis for Heterogeneous and Multicore Systems; Chapter 2: On the Impact of the Heterogeneous Multicore and Many-Core Platforms on Iterative Solution Methods and Preconditioning Techniques; 2.1 Introduction8 a2.2 General Description of Iterative Methods and Preconditioning2.3 Preconditioning Techniques; 2.4 Defect-Correction Technique; 2.5 Multigrid Method; 2.6 Parallelization of Iterative Methods; 2.7 Heterogeneous Systems; 2.8 Maintenance and Portability; 2.9 Conclusion; Acknowledgments; References; Chapter 3: Efficient Numerical Solution of 2D Diffusion Equation on Multicore Computers; 3.1 Introduction; 3.2 Test Case; 3.3 Parallel Implementation; 3.4 Results; 3.5 Discussion; 3.6 Conclusion; Acknowledgment; References8 aChapter 4: Parallel Algorithms for Parabolic Problems on Graphs in Neuroscience4.1 Introduction; 4.2 Formulation of the Discrete Model; 4.3 Parallel Algorithms; 4.4 Computational Results; 4.5 Conclusions; Acknowledgments; References; Part III: Communication and Storage Considerations in High-Performance Computing; Chapter 5: An Overview of Topology Mapping Algorithms and Techniques in High-Performance Computing; 5.1 Introduction; 5.2 General Overview; 5.3 Formalization of the Problem; 5.4 Algorithmic Strategies for Topology Mapping; 5.5 Mapping Enforcement Techniques; 5.6 Survey of Solutions8 a5.7 Conclusion and Open ProblemsAcknowledgment; References; Chapter 6: Optimization of Collective Communication for Heterogeneous HPC Platforms; 6.1 Introduction; 6.2 Overview of Optimized Collectives and Topology-Aware Collectives; 6.3 Optimizations of Collectives on Homogeneous Clusters; 6.4 Heterogeneous Networks; 6.5 Topology- and Performance-Aware Collectives; 6.6 Topology as Input; 6.7 Performance as Input; 6.8 Non-MPI Collective Algorithms for Heterogeneous Networks; 6.9 Conclusion; Acknowledgments; References; Chapter 7: Effective Data Access Patterns on Massively Parallel Processors8 a7.1 Introduction7.2 Architectural Details; 7.3 K-Model; 7.4 Parallel Prefix Sum; 7.5 Bitonic Sorting Networks; 7.6 Final Remarks; Acknowledgments; References; Chapter 8: Scalable Storage I/O Software for Blue Gene Architectures; 8.1 Introduction; 8.2 Blue Gene System Overview; 8.3 Design and Implementation; 8.4 Conclusions and Future Work; Acknowledgments; References; Part IV: Efficient Exploitation of Heterogeneous Architectures; Chapter 9: Fair Resource Sharing for Dynamic Scheduling of Workflows on Heterogeneous Systems; 9.1 Introduction; 9.2 Concurrent Workflow Scheduling 0aHigh performance computing. 4aHigh performance computing. 7aCOMPUTERSxComputer Literacy.2bisacsh 7aCOMPUTERSxComputer Science.2bisacsh 7aCOMPUTERSxData Processing.2bisacsh 7aCOMPUTERSxHardwarexGeneral.2bisacsh 7aCOMPUTERSxInformation Technology.2bisacsh 7aCOMPUTERSxMachine Theory.2bisacsh 7aCOMPUTERSxReference.2bisacsh 7aHigh performance computing.2fast0(OCoLC)fst00956032 7aHigh performance computing.2local 4aElectronic books. 0aElectronic books.1 aŽilinskas, J.q(Julius),d1973-08iPrint version:aJeannot, Emmanuel.tHigh performance computing on complex environments.dHoboken, New Jersey : John Wiley & Sons, [2014]z9781118712054w(DLC)  2013048363w(OCoLC)861477993 0aWiley series on parallel and distributed computing.40uhttp://onlinelibrary.wiley.com/book/10.1002/9781118711897zWiley Online Library  aBooks 24x7bB247nbks00063580  aCoutts Information ServicesbCOUTn28112376  aEBL - Ebook LibrarybEBLBnEBL1666528  aebrarybEBRYnebr10860999  aEBSCOhostbEBSCn756266  aIngram Digital eBook CollectionbIDEBncis28112376  aRecorded Books, LLCbRECEnrbeEB00438516  aYBP Library ServicesbYANKn11765728  aYBP Library ServicesbYANKn11072424  aYBP Library ServicesbYANKn13035629  a92bDG1  c13295d13295
