About the Book

Chapter 1: IntroductionSets expectation that book describes SYCL 1.2.1 with Intel extensions, and that most extensions are proof points of features that should end up in a future version of SYCL. Overview notion of different accelerator architectures doing well on different workloads, and introduce accelerator archs (but don't overdo the topic). Overview/level setting on parallelism and relevant terminology, language landscape, SYCL history.- SYCL key feature overview (single source, C++, multi-accelerator) - intended to draw people in and show simple code- Language versions and extensions covered by this book- Mixed-architecture compute and modern architectures- Classes of parallelism- Accelerator programming landscape (OpenMP, CUDA, TBB, OpenACC, AMD HCC, Kokkos, RAJA)- Evolution of SYCL
Chapter 2: Where code executesDescribes which parts of code run natively on CPU versus on "devices". Differentiate between accelerator devices and the "host device". Show more code to increase reader familiarity with program structure.- Single source programming model- Built-in device selectors- Writing a custom device selector
Chapter 3: Data management and ordering the uses of dataOverview the primary ways that data is accessible by both host and device(s): USM and buffers. Introduce command groups as futures for execution, and concept of dependencies between nodes forming a DAG.- Intro- Unified Shared Memory- Buffers- DAG mechanism
Chapter 4: Expressing parallelismThe multiple alternative constructs for expressing parallelism are hard to comprehend from the spec, and for anyone without major parallel programming experience. This chapter must position the parallelism mechanisms relative to each other, and leave the reader with a conceptual understanding of each, plus an understand of how to use the most common forms.- Parallelism within kernels- Overview of language features for expressions of parallelism- Basic data parallel kernels- Explicit ND-Range kernels- Hierarchical parallelism kernels- Choosing a parallelism/coding style
Chapter 5: Error handlingSYCL uses C++-style error handling. This is different/more modern than people using OpenCL and CUDA are used to. This chapter must frame the differences, and provide samples from which readers can manage exceptions easily in their code.- Exception-based- Synchronous and asynchronous exceptions- Strategies for error management- Fallback queue mechanism
Chapter 6: USM in detailUSM is a key usability feature when porting code, from C++ for example. When mixed with differing hardware capabilities, the USM landscape isn't trivial to understand. This key chapter must leave the reader with an understanding of USM on different hardware capabilities, what is guaranteed at each level, and how to write code with USM features.- Usability- Device capability levels- Allocating memory- Use of data in kernels- Sharing of data between host and devices- Data ownership and migration- USM as a usability feature- USM as a performance feature- Relation to OpenCL SVM
Chapter 7: Buffers in detailBuffers will be available on all hardware, and are an important feature for people writing code that doesn't have pointer-based data structures, particularly when implicit dependence management is desired. This chapter must cover the more complex aspects of buffers in an accessi
About the Author: James Reinders is a consultant with more than three decades experience in Parallel Computing, and is an author/co-author/editor of nine technical books related to parallel programming. He has had the great fortune to help make key contributions to two of the world's fastest computers (#1 on Top500 list) as well as many other supercomputers, and software developer tools. James finished 10,001 days (over 27 years) at Intel in mid-2016, and now continues to write, teach, program, and do consulting in areas related to parallel computing (HPC and AI).
