Single processing units have now reached a point where further major improvements in their performance are restricted by their physical limitations. This is causing a slowing down in advances at the same time as new scientific challenges are demanding exascale speed. This has meant that parallel processing has become key to High Performance Computing (HPC). This book contains the proceedings of the 14th biennial ParCo conference, ParCo2011, held in Ghent, Belgium. The ParCo conferences have traditionally concentrated on three main themes: Algorithms, Architectures and Applications. Nowadays though, the focus has shifted from traditional multiprocessor topologies to heterogeneous and manycores, incorporating standard CPUs, GPUs (Graphics Processing Units) and FPGAs (Field Programmable Gate Arrays). These platforms are, at a higher abstraction level, integrated in clusters, grids and clouds. The papers presented here reflect this change of focus. New architectures, programming tools and techniques are also explored, and the need for exascale hardware and software was also discussed in the industrial session of the conference.This book will be of interest to all those interested in parallel computing today, and progress towards the exascale computing of tomorrow.

"High-performance computing (HPC) systems are more powerful than ever before. However, this rise in performance brings with it greater complexity, presenting significant challenges for researchers who wish to use these systems for their scientific work. This dissertation explores the development of scalable programming solutions for scientific computing . These solutions aim to be effective across a diverse range of computing platforms, from personal desktops to advanced supercomputers. To better understand HPC systems , this dissertation begins with a literature review on exascale supercomputers, massive systems capable of performing 1018 floating-point operations per second. This review combines both manual and data-driven analyses, revealing that while traditional challenges of exascale computing have largely been addressed, issues like software complexity and data volume remain. Additionally, the dissertation introduces the open-source software tool (called LitStudy) developed for this research. Next, this dissertation introduces two novel programming systems . The first system (called Rocket) is designed to scale all- versus-all algorithms to massive datasets. It features a multi-level software-based cache, a divide-and-conquer approach, hierarchical work-stealing, and asynchronous processing to maximize data reuse, exploit data locality, dynamically balance workloads, and optimize resource utilization. The second system (called Lightning) aims to scale existing single-GPU kernel functions across multiple GPUs, even on different nodes, with minimal code adjustments. Results across eight benchmarks on up to 32 GPUs show excellent scalability. The dissertation concludes by proposing a set of design principles for developing parallel programming systems for scalable scientific computing . These principles, based on lessons from this PhD research, represent significant steps forward in enabling researchers to efficiently utilize HPC systems."--

In 2022, the United States installed its first exascale computing system for the Department of Energy (DOE) Office of Science, with an National Nuclear Security Administration (NNSA) system scheduled for 2023. The DOE Exascale Computing Project (ECP)2 has developed new applications capabilities, parallelization approaches, and software tools, while co-developing the computing systems in collaboration with vendor partners. The NNSA is positioned to take full advantage of exascale computing, but demand for more computing will continue to grow beyond exascale, driven by both familiar applications and new mission drivers and new computational approaches that will use high-end computing. Visionary leaders and creativity will be needed to move existing codes to next-generation platforms, to reconsider the use of advanced computing for current and emerging mission problems, and to envision new types of computing systems, algorithmic techniques implemented in software, partnerships, and models of system acquisition. This report reviews the future of computing beyond exascale computing to meet national security needs at the National Nuclear Security Administration, including computing needs over the next 20 years that exascale computing will not support; future computing technologies for meeting those needs including quantum computing and other novel hardware, computer architecture, and software; and the likely trajectory of promising hardware and software technologies and obstacles to their development and their deployment by NNSA.

The US, Europe, Japan and China are racing to develop the next generation of supercomputers – exascale machines capable of 10 to the 18th power calculations a second – by 2020. But the barriers are daunting: the challenge is to change the paradigm of high-performance computing. The 2012 biennial high performance workshop, held in Cetraro, Italy in June 2012, focused on the challenges facing the computing research community to reach exascale performance in the next decade. This book presents papers from this workshop, arranged into four major topics: energy, scalability, new architectural concepts and programming of heterogeneous computing systems. Chapter 1 introduces the status of present supercomputers, which are still about two orders of magnitude separated from the exascale mark. Chapter 2 examines energy demands, a major limiting factor of today's fastest supercomputers; the quantum leap in performance required for exascale computing will require a shift in architectures and technology. In Chapter 3, scalable computer paradigms for dense linear algebra on massive heterogeneous systems are presented, and Chapter 4 discusses architectural concepts. Finally, Chapter 5 addresses the programming of heterogeneous systems. This book will be of interest to all those wishing to understand how the development of modern supercomputers is set to advance in the next decade.
