Book Description
CUDA-aware Message Passing Interface (MPI) libraries like MVAPICH2-GDR have rapidly evolved to keep up with the demand for efficient GPU buffer-based communication by incorporating the latest technological advances to drive down communication latency significantly. However, with the advent of Deep Learning (DL), vendors have started to introduce libraries that are DL-focused, but not MPI-compliant – like the NVIDIA Collective Communications Library (NCCL). Furthermore, there is a lack of a single common standardized benchmarking tool to evaluate the performance of both MPI and NCCL operations. In this work, we introduce a new set of collective benchmarks within OSU-Micro Benchmarks (OMB) to evaluate the performance of NCCL operations in a manner that is semantically equivalent to MPI benchmarks. We then tackle the challenge to see if modern CUDA-aware MPI libraries like MVAPICH2-GDR can take advantage of advances in collective communications libraries like NCCL to provide high-performance MPI-compliant collective communication primitives for High-Performance Computing (HPC) and DL applications. We incorporate the ability to invoke NCCL API into MVAPICH2-GDR’s tuning framework in order to select the best algorithm for any given message size. Finally, we evaluate the performance of our designs by investigating the improvement in latency at different message sizes and scales on the Lassen supercomputing system using OMB. The designs developed as a part of this thesis will be made available in future releases of MVAPICH2-GDR and OMB.

Book Description
Amber is the collective name for a suite of programs that allow users to carry out molecular dynamics simulations, particularly on biomolecules. None of the individual programs carries this name, but the various parts work reasonably well together, and provide a powerful framework for many common calculations. The term Amber is also used to refer to the empirical force fields that are implemented here. It should be recognized, however, that the code and force field are separate: several other computer packages have implemented the Amber force fields, and other force fields can be implemented with the Amber programs. Further, the force fields are in the public domain, whereas the codes are distributed under a license agreement. The Amber software suite is divided into two parts: AmberTools21, a collection of freely available programs mostly under the GPL license, and Amber20, which is centered around the pmemd simulation program, and which continues to be licensed as before, under a more restrictive license. Amber20 represents a significant change from the most recent previous version, Amber18. (We have moved to numbering Amber releases by the last two digits of the calendar year, so there are no odd-numbered versions.) Please see https://ambermd.org for an overview of the most important changes. AmberTools is a set of programs for biomolecular simulation and analysis. They are designed to work well with each other, and with the “regular” Amber suite of programs. You can perform many simulation tasks with AmberTools, and you can do more extensive simulations with the combination of AmberTools and Amber itself. Most components of AmberTools are released under the GNU General Public License (GPL). A few components are in the public domain or have other open-source licenses. See the README file for more information.

Book Description
This IBM® Redpaper publication describes the architecture, installation procedure, and results for running a typical training application that works on an automotive data set in an orchestrated and secured environment that provides horizontal scalability of GPU resources across physical node boundaries for deep neural network (DNN) workloads. This paper is mostly relevant for systems engineers, system administrators, or system architects that are responsible for data center infrastructure management and typical day-to-day operations such as system monitoring, operational control, asset management, and security audits. This paper also describes IBM Spectrum® LSF® as a workload manager and IBM Spectrum Discover as a metadata search engine to find the right data for an inference job and automate the data science workflow. With the help of this solution, the data location, which may be on different storage systems, and time of availability for the AI job can be fully abstracted, which provides valuable information for data scientists.

Book Description
This book addresses the emerging area of cloud computing, providing a comprehensive overview of the research areas, recent work and open research problems. The move to cloud computing is no longer merely a topic of discussion; it has become a core competency that every modern business needs to embrace and excel at. It has changed the way enterprise and internet computing is viewed, and this success story is the result of the long-term efforts of computing research community around the globe. It is predicted that by 2026 more than two-thirds of all enterprises across the globe will be entirely run in cloud. These predictions have led to huge levels of funding for research and development in cloud computing and related technologies. Accordingly, universities across the globe have incorporated cloud computing and its related technologies in their curriculum, and information technology (IT) organizations are accelerating their skill-set evolution in order to be better prepared to manage emerging technologies and public expectations of the cloud, such as new services.
