Hierarchical Scheduling in Parallel and Cluster Systems available in PDF, EPUB and Kindle. Multiple processor systems are an important class of parallel systems. Over the years, several architectures have been proposed to build such systems to satisfy the requirements of high performance computing. These architectures span a wide variety of system types. At the low end of the spectrum, we can build a small, shared-memory parallel system with tens of processors. These systems typically use a bus to interconnect the processors and memory. Such systems, for example, are becoming commonplace in high-performance graph ics workstations. These systems are called uniform memory access (UMA) multiprocessors because they provide uniform access of memory to all pro cessors. These systems provide a single address space, which is preferred by programmers. This architecture, however, cannot be extended even to medium systems with hundreds of processors due to bus bandwidth limitations. To scale systems to medium range i. e. , to hundreds of processors, non-bus interconnection networks have been proposed. These systems, for example, use a multistage dynamic interconnection network. Such systems also provide global, shared memory like the UMA systems. However, they introduce local and remote memories, which lead to non-uniform memory access (NUMA) architecture. Distributed-memory architecture is used for systems with thousands of pro cessors. These systems differ from the shared-memory architectures in that there is no globally accessible shared memory. Instead, they use message pass ing to facilitate communication among the processors. As a result, they do not provide single address space.

Hierarchical Distributed Loop Self-scheduling Schemes on Cluster and Cloud Systems available in PDF, EPUB and Kindle. Loops are the largest source of parallelism in many scientific applications. Parallelization of irregular loop applications is a challenging problem to achieve scalable performance on cluster and cloud systems. In distributed systems, load balance, communication and synchronization overhead must be taken considered. For cluster systems, previous research proposed an effective Master-Worker model on clusters for distributed self-scheduling schemes that apply to parallel loops with independent iterations. However, this model has not been applied to large-scale clusters. Cloud computing infrastructure offers computing resources as a collection of virtual machines by different hardware configurations, which is transparent to end users. In fact, the computing powers of these virtual machines instances are different and the system behaves as a heterogeneous environment. Thus, scheduling and load balancing for high performance computations become challenging issues. We propose a hierarchical distributed approach suitable for scheduling parallel loops. We implemented our algorithms(or schemes) on a large scale homogeneous cluster and also on a heterogeneous cloud environment. We evaluated various performance aspects associated with our distributed scheduling algorithms. Modern cloud systems provide high availability, fault tolerance, disaster recovery and monitoring for the most critical environments. In the event of failures, cloud systems with fault tolerance can continue to operate properly. We also propose a fault tolerant hierarchical distributed algorithms to survive from hardware/software faults and reschedule the rest of workload.

Download and read online ebook Performance Tools and Applications to Networked Systems write by Maria Carla Calzarossa. This book was released on 2004-04-22. Performance Tools and Applications to Networked Systems available in PDF, EPUB and Kindle. This book presents revised versions of tutorial lectures given at the IEEE/CS symposium on modeling, analysis, and simulation of computer and telecommunication systems held in Orlando, FL, USA in October 2003. The lectures are grouped in three parts on performance and QoS of modern wired and wireless networks, current advances in performance modeling and simulation, and other specific applications of these methodologies. This tutorial book is targeted to both practitioners and researchers. The practitioner will benefit from numerous pointers to performance and QoS issues; the pedagogical style and plenty of references can be of great use in solving practical problems. The researcher and advanced student are offered a representative set of topics not only for their research value but also for their novelty and use in identifying areas of active research.
