This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of heterogeneous computing resources, such as graphics processing units or other specialized co-processors, has become widespread in recent years because of their performance and energy efficiency advantages. Operating system approaches that are limited to optimizing CPU usage are no longer sufficient for the efficient utilization of systems that comprise diverse resource types. Enabling task preemption on these architectures and migration of tasks between different resource types at run-time is not only key to improving the performance and energy consumption but also to enabling automatic scheduling methods for heterogeneous compute nodes. This thesis proposes novel techniques for run-time management of heterogeneous resources and enabling tasks to migrate between diverse hardware. It provides fundamental work towards future operating systems by discussing implications, limitations, and chances of the heterogeneity and introducing solutions for energy- and performance-efficient run-time systems. Scheduling methods to utilize heterogeneous systems by the use of a centralized scheduler are presented that show benefits over existing approaches in varying case studies.

Download or read book High Performance Heterogeneous Acceleration written by Beayna Grigorian and published by . This book was released on 2014 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time, low-energy constraints as well as large amounts of data continue to challenge high performance computing (HPC). As a result, it has become increasingly important to advance the capabilities of high performance architectures. Single instruction multiple data (SIMD) designs are ideal for targeting data- and compute-intensive HPC workloads. Accelerator-rich architectures, in particular, implement application-specific functionality directly in hardware via on-chip accelerators, providing many orders of magnitude improvement in power efficiency and performance. Unlike instruction-based SIMD architectures, such as graphics processing units (GPUs), accelerator-rich designs avoid the overhead for processing instructions while maintaining flexibility by way of accelerator composition and virtualization. This dissertation explores various aspects of hardware-based acceleration, including fine-grained vs. coarse-grained designs, ASIC-based vs. FPGA-based implementations, and domain-specific vs. domain-adaptive systems. While accelerator-rich designs are well-suited for exploiting data-level parallelism, they are highly susceptible (as are all SIMD architectures) to performance degradation due to divergence in control flow. Since HPC workloads can contain various types and amounts of control flow, this SIMD divergence issue must be addressed in order for accelerator-based designs to yield more effective HPC platforms. As such, this work also investigates an approximation-based approach for eliminating control flow. We exploit the intelligent learning capabilities of neural networks to approximate and regularize the control flow regions of applications, thereby trading off precision for performance gains. Furthermore, we develop light-weight checks to ensure output reliability at runtime, allowing our neural-network-based approximations to be leveraged in a dynamically adaptive fashion. Our work culminates in the following hybrid approach: a heterogeneous SIMD platform with both precise (conventional) and approximate (neural) accelerators, which are managed using online error control mechanisms. For the implementation, ASIC components are incorporated into the platform; also, approximation control methods, including NN training tools, static software interfaces, and dynamic hardware components, are developed to maintain acceptable error rates. Taking inspiration from the partial-observability and stochasticity of the world around us, this work combines data-parallel acceleration with neural approximation in an effort to advance high performance computation.

Book excerpt: element of relationships between entities, but, above all, it positively influences the building of an organization's intellectual capital. This capital can be defined in different ways, but its definition always references elements that determine the potential of sustainable organizations, often in human, social, relational, organizational, and innovation dimensions. Trust is increasingly becoming the key determinant of this capital (Kożuch, Lenart-Gansiniec, 2017). Trust also has a number of different definitions. However, the basis of many of these definitions is the building of relationships focused on developing some kind of individual or inter-organizational link. Organizational trust is a complicated concept, and it is the basis of all organized activities performed by people in the organization, largely because trust is needed to develop relationships with integrity and commitment. Thus, it is interesting to study the relationship between trust and the building of the intellectual capital of sustainable organizations. Indeed, intellectual capital plays a special role here. It is a guide and a platform for achieving not only a competitive advantage for the sustainable organization, but also a source of value creation in the short and long term. Thus, this strategic hybrid, composed of a business model, strategy, and business processes, is favorable to the development of intellectual capital (Jabłoński 2017). Trust is an element that ties this capital to relationships in business. Moreover, it has an integrated character (R.C. Mayer, J. H. Davis, F. D. Schoorman 1995). Assuming that, nowadays, the network paradigm is becoming increasingly important, it is worth asking how the mechanism of building trust-based intellectual capital in a sustainable organization functions as its key asset in the network environment.
Download or read book Co Scheduling of HPC Applications written by C. Trinitis and published by IOS Press. This book was released on 2017-01-05 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-performance computing (HPC) has become an essential tool in the modern world. However, systems frequently run well below theoretical peak performance, with only 5% being reached in many cases. In addition, costly components often remain idle when not required for specific programs, as parts of the HPC systems are reserved and used exclusively for applications. A project was started in 2013, funded by the German Ministry of Education and Research (BMBF), to find ways of improving system utilization by compromising on dedicated reservations for HPC codes and applying co-scheduling of applications instead. The need was recognized for international discussion to find the best solutions to this HPC utilization issue, and a workshop on co-scheduling in HPC, open to international participants – the COSH workshop – was held for the first time at the European HiPEAC conference, in Prague, Czech Republic, in January 2016. This book presents extended versions of papers submitted to the workshop, reviewed for the second time to ensure scientific quality. It also includes an introduction to the main challenges of co-scheduling and a foreword by Arndt Bode, head of LRZ, one of Europe's leading computer centers, as well as a chapter corresponding to the invited keynote speech by Intel, whose recent extensions to their processors allow for better control of co-scheduling.

Download or read book Scheduling Tasks Over Multicore Machines Enhanced with Accelerators written by Cédric Augonnet and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multicore machines equipped with accelerators are becoming increasingly popular in the HighPerformance Computing ecosystem. Hybrid architectures provide significantly improved energyefficiency, so that they are likely to generalize in the Manycore era. However, the complexity introducedby these architectures has a direct impact on programmability, so that it is crucial toprovide portable abstractions in order to fully tap into the potential of these machines. Pure offloadingapproaches, that consist in running an application on regular processors while offloadingpredetermined parts of the code on accelerators, are not sufficient. The real challenge is to buildsystems where the application would be spread across the entire machine, that is, where computationwould be dynamically scheduled over the full set of available processing units.In this thesis, we thus propose a new task-based model of runtime system specifically designedto address the numerous challenges introduced by hybrid architectures, especially in terms of taskscheduling and of data management. In order to demonstrate the relevance of this model, we designedthe StarPU platform. It provides an expressive interface along with flexible task schedulingcapabilities tightly coupled to an efficient data management. Using these facilities, together witha database of auto-tuned per-task performance models, it for instance becomes straightforward todevelop efficient scheduling policies that take into account both computation and communicationcosts. We show that our task-based model is not only powerful enough to provide support forclusters, but also to scale on hybrid manycore architectures.We analyze the performance of our approach on both synthetic and real-life workloads, andshow that we obtain significant speedups and a very high efficiency on various types of multicoreplatforms enhanced with accelerators.
