Download or read book Multithreaded Model for Dynamic Load Balancing Parallel Adaptive PDE Computations written by Nikos Chrisochoides and published by . This book was released on 1995 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We present a multithreaded model for the dynamic load- balancing of numerical, adaptive computations required for the solution of Partial Differential Equations (PDEs) on multiprocessors. Multithreading is used as a means of exploring concurrency at the processor level in order to tolerate synchronization costs inherent to traditional (non-threaded) parallel adaptive PDE solvers. Our preliminary analysis for parallel, adaptive PDE solvers indicates that multithreading can be used as a mechanism to mask overheads required for the dynamic balancing of processor workloads with computations required for the actual numerical solution of the PDEs. Also, multithreading can simplify the implementation of dynamic load-balancing algorithms, a task that is very difficult for traditional data parallel adaptive PDE computations. Unfortunately, multithreading does not always simplify program complexity, often makes code re-usability difficult, and increases software complexity."

Download or read book Adapting the Polytope Model for Dynamic and Speculative Parallelization written by Alexandra Jimborean and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we present a Thread-Level Speculation (TLS) framework whose main feature is to speculatively parallelize a sequential loop nest in various ways, to maximize performance. We perform code transformations by applying the polyhedral model that we adapted for speculative and runtime code parallelization. For this purpose, we designed a parallel code pattern which is patched by our runtime system according to the profiling information collected on some execution samples. We show on several benchmarks that our framework yields good performance on codes which could not be handled efficiently by previously proposed TLS systems.

Available in PDF, EPUB and Kindle. Book excerpt: Future multicore processors will be heterogeneous, be increasingly less reliable, and operate in dynamically changing operating conditions. Such environments will result in a constantly varying pool of hardware resources which can complicate the programmer's task of efficiently exposing an application's parallelism onto these resources. Coupled with this complexity is the diverse set of performance objectives, such as latency, throughout, energy, power and resources, that users may desire. This dissertation proposes to automate the process of exposing an application's parallelism, in order to alleviate programmers from the burden of this complexity. It develops Varuna, a system that dynamically, continuously, rapidly and transparently adapts an application's parallelism to best match the instantaneous capabilities and availability of the hardware resources and the characteristics of the application, while optimizing different performance objectives. To facilitate rapid parallelism adaptation, this dissertation develops a holistic and resource-agnostic scalability model based on Amdahl's law. Varuna first employs the model to rapidly estimates changes in efficiency during an application's parallel execution. It then uses formulae, derived from the model, to instantaneously determine the optimum degree of parallelism (DoP) to employ for different performance objectives and automatically guides the execution to the computed DoP. In order for Varuna to transparently guide the application's parallel execution to the computed DoP, this dissertation proposes to employ a novel primitive called a virtual task (vtask). Vtasks decouple application-level parallelism from hardware parallelism. They are progress-aware entities and give Varuna the flexibility needed to transparently control an application's parallel execution, without hampering its forward progress. Varuna is programming model independent. It retains the existing programming abstractions and can be applied to both task-based and multithreaded shared memory parallel applications. Further, it requires no changes to the application or the Operating System, and can tackle arbitrary parallel applications that use standard APIs. This dissertation demonstrates Varuna for three different shared memory parallel programming APIs: Pthreads, Intel Thread Building Blocks (TBB), and Prometheus. This dissertation evaluates Varuna in three different execution environments, isolated, multiprogrammed and asymmetric, using unaltered C/C++ Pthreads, TBB and Prometheus applications from various standard benchmark suites, on three different real hardware platforms with different microarchitectural resource capabilities. Regardless of the execution environment, Varuna always outperformed the state-of-the-art approaches for the performance objectives considered.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, applications permeated by advances in digital signal processing have undergone unprecedented growth in capabilities. The editors and authors of High Performance Embedded Computing Handbook: A Systems Perspective have been significant contributors to this field, and the principles and techniques presented in the handbook are reinforced by examples drawn from their work. The chapters cover system components found in today’s HPEC systems by addressing design trade-offs, implementation options, and techniques of the trade, then solidifying the concepts with specific HPEC system examples. This approach provides a more valuable learning tool, Because readers learn about these subject areas through factual implementation cases drawn from the contributing authors’ own experiences. Discussions include: Key subsystems and components Computational characteristics of high performance embedded algorithms and applications Front-end real-time processor technologies such as analog-to-digital conversion, application-specific integrated circuits, field programmable gate arrays, and intellectual property–based design Programmable HPEC systems technology, including interconnection fabrics, parallel and distributed processing, performance metrics and software architecture, and automatic code parallelization and optimization Examples of complex HPEC systems representative of actual prototype developments Application examples, including radar, communications, electro-optical, and sonar applications The handbook is organized around a canonical framework that helps readers navigate through the chapters, and it concludes with a discussion of future trends in HPEC systems. The material is covered at a level suitable for practicing engineers and HPEC computational practitioners and is easily adaptable to their own implementation requirements.
