Workshop Nvidia HPC SDK

Overview

The new NVIDIA HPC SDK significantly reshapes the diverse GPU metaprogramming approaches previously taken by OpenACC and Thrust/Bolt. With a new GPU-enabled std::par framework, a developer gets a vendor-neutral access to multicore CPUs and GPUs in a more unified fashion. In this webinar, we explain how to start using std::par in existing applications in typical software engineering scenarios. Furthermore, we focus on the new Nsight profiling tools, which are now free of a lot of limitations of the previous generation NVIDIA Visual Profiler. Finally, the webinar covers the new CUDA Fortran features, as well as the Python bindings essential for any modern compute application.

Date and Time

Tuesday, July 6th from 10am to 1pm The workshop will be held online, details will follow shortly before the meeting.

Agenda

Session 1 (10:00–11:30): New NVIDIA HPC SDK for More Productive GPU Computing

• New focuses of NVIDIA HPC SDK: performance, portability and productivity
• How the new HPC SDK is different from CUDA Toolkit and PGI Compiler Suite
• C++17 std::par constructs as an alternative to OpenACC directives and CUDA Thrust
  • Essential elements: containers, iterators and lamda functions
  • Thrust-like counting iterators
  • Explicit and implicit memory transfers
• NVIDIA HPC SDK in the programming ecosystem
  • Intermixing HPC SDK and CUDA Toolkit
  • CMake support for NVC++ compiler
  • Switching between std::par backends, targeting different GPUs with SyclParallelSTL

Session 2 (11:40-13:00): Profiling, language and binding features of NVIDIA HPC SDK

• Next generation profiling tools: NSight Systems and NSight Compute
  • Connecting Nsight profilers to remote cloud GPUs
• Fortran 2003/2008 and CUDA Fortran in NVIDIA HPC SDK
• Python bindings for GPU applications
  • Using NVC++ compiler to build Python API around native GPU code
  • Preparing a pybind11 wrapper for C++17 std::par and CUDA Fortran applications
