This book was released on 2010 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Performance Computing is characterized by the latest technological evolutions in computing architectures and by the increasing needs of applications for computing power. A particular middleware called Resource and Job Management System (RJMS), is responsible for delivering computing power to applications. The RJMS plays an important role in HPC since it has a strategic place in the whole software stack because it stands between the above two layers. However, the latest evolutions in hardware and applications layers have provided new levels of complexities to this middleware. Issues like scalability, management of topological constraints, energy efficiency and fault tolerance have to be particularly considered, among others, in order to provide a better system exploitation from both the system and user point of view. This dissertation provides a state of the art upon the fundamental concepts and research issues of Resources and Jobs Management Systems. It provides a multi-level comparison (concepts, functionalities, performance) of some Resource and Jobs Management Systems in High Performance Computing. An important metric to evaluate the work of a RJMS on a platform is the observed system utilization. However, studies and logs of production platforms show that HPC systems in general suffer of significant un-utilization rates. Our study deals with these clusters' un-utilization periods by proposing methods to aggregate otherwise un-utilized resources for the benefit of the system or the application. More particularly this thesis explores RJMS level mechanisms: 1) for increasing the jobs valuable computation rates in the high volatile environments of a lightweight grid context, 2) for improving system utilization with malleability techniques and 3) providing energy efficient system management through the exploitation of idle computing machines. The experimentation and evaluation in this type of contexts provide important complexities due to the inter-dependency of multiple parameters that have to be taken into control. In this thesis we have developed a methodology based upon real-scale controlled experimentation with submission of synthetic or real workload traces.

Download or read book High Performance Computing in Clouds written by Edson Borin and published by Springer Nature. This book was released on 2023-07-05 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings a thorough explanation on the path needed to use cloud computing technologies to run High-Performance Computing (HPC) applications. Besides presenting the motivation behind moving HPC applications to the cloud, it covers both essential and advanced issues on this topic such as deploying HPC applications and infrastructures, designing cloud-friendly HPC applications, and optimizing a provisioned cloud infrastructure to run this family of applications. Additionally, this book also describes the best practices to maintain and keep running HPC applications in the cloud by employing fault tolerance techniques and avoiding resource wastage. To give practical meaning to topics covered in this book, it brings some case studies where HPC applications, used in relevant scientific areas like Bioinformatics and Oil and Gas industry were moved to the cloud. Moreover, it also discusses how to train deep learning models in the cloud elucidating the key components and aspects necessary to train these models via different types of services offered by cloud providers. Despite the vast bibliography about cloud computing and HPC, to the best of our knowledge, no existing manuscript has comprehensively covered these topics and discussed the steps, methods and strategies to execute HPC applications in clouds. Therefore, we believe this title is useful for IT professionals and students and researchers interested in cutting-edge technologies, concepts, and insights focusing on the use of cloud technologies to run HPC applications.

Download or read book On the User scheduler Relationship in High performance Computing written by Cynthia Bailey Lee and published by . This book was released on 2009 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: To effectively manage High-Performance Computing (HPC) resources, it is essential to maximize return on the substantial infrastructure investment they entail. One prerequisite to success is the ability of the scheduler and user to productively interact. This work develops criteria for measuring productivity, analyzes several aspects of the user-scheduler relationship via user studies, and develops solutions to some vexing barriers between users and schedulers. The five main contributions of this work are as follows. First, this work quantifies the desires of the user population and represents them as a utility function. This contribution is in four parts: a survey-based study collecting utility data from users of a supercomputer system, augmentation of the Standard Workload Format to enable scheduler research using utility functions, and a model for synthetically generating utility function-augmented workloads. Second, a number of the classic scheduling disciplines are evaluated by their ability to maximize aggregate utility of all users, using the synthetic utility functions. These evaluations show the performance impact of inaccurate runtime estimates, contradicting an oft quoted prior result [55] that inaccuracy of estimates leads to better scheduling. Third, a scheduler optimizing the aggregate utility of all users, using a genetic algorithm heuristic, is demonstrated. This contribution includes two software artifacts: an implementation of the genetic algorithm (GA) scheduler, and a modular, extensible scheduler simulation framework that simulates several classic scheduling disciplines and is interoperable with the Standard Workload Format. Fourth, the ability of users to productively interact with this scheduler by providing an accurate estimate of their resource (run time) needs is examined. This contribution consists of formalizing a frequent casual assertion from the scheduling literature, that users typically "pad" runtime estimates, into an explicit Padding Hypothesis, and then falsifying the hypothesis via a survey-based study of users of a supercomputer system. Specifically, absent an incentive to pad-and including incentives to be accurate-the inaccuracy of runtime estimates only improved from an average of 61% inaccurate to an average of 57% inaccurate. This contribution has implications not only for the proposed genetic algorithm scheduler, but for any scheduler that asks users for an estimate, which currently includes virtually all parallel job schedulers both in production use and proposed in the literature. Fifth, a survey of users of a supercomputer system and associated simulations explore the feasibility of removing one of the defining constraints of the parallel job scheduling problem-the non-preemptability of running jobs. An investigation of users' current checkpointing habits produced a workload labeled with per-job checkpoint information, enabling simulation of a checkpoint-aware GA scheduler that may preempt running jobs as it optimizes aggregate utility. Lifting the non-preemptability constraint improves performance of the GA scheduler by 16% (and 23% compared to classic EASY algorithm), including overhead penalties for job termination and restart.
