Introduction to Parallel Programming

  • Learn about parallelism in a conceptual way, as well as how to express it with OpenACC. Topics that will be covered are as follows:
    • Introduction to parallelism
    • The goals of OpenACC
    • Basic parallelization of code using OpenACC

Profiling with OpenACC

  • Learn how to build and compile an OpenACC code, the importance of profiling, and how to use the NVIDIA Nsight™ Systems profiler. Topics that will be covered are as follows:
    • Compiling sequential and OpenACC code
    • The importance of code profiling
    • Profiling sequential and OpenACC multicore code
    • Technical introduction to the code used in introductory modules

Introduction to OpenACC Directives

  • Learn how to parallelize your code with OpenACC directives and understand the differences between parallel, kernel, and loop directives. Topics that will be covered are as follows:
    • The Parallel directive
    • The Kernels directive
    • The Loop directive

GPU Programming with OpenACC

  • Learn about the differences between GPUs and multicore CPUs, and manage memory with CUDA Unified Memory. Topics that will be covered are as follows:
    • Definition of a GPU
    • Basic OpenACC data management
    • CUDA Unified Memory
    • Profiling GPU applications

Data Management with OpenACC

  • Learn how to explicitly manage data movement with OpenACC data directives to reduce data transfers. Topics that will be covered are as follows:
    • OpenACC data directive/clauses
    • OpenACC structured data region
    • OpenACC unstructured data region
    • OpenACC update directive
    • Data management with C/C++ Structs/Classes

Loop Optimizations with OpenACC

  • Understand the various levels of parallelism on a GPU and learn ways to extract more parallelism with OpenACC by optimizing loops in your code. Topics that will be covered are as follows:
    • Seq/Auto clause
    • Independent clause
    • Reduction clause
    • Collapse clause
    • Tile clause
    • Gang, Worker, Vector
