HPC Compilers

HPC Compilers User’s Guide: This guide describes how to use the HPC Fortran, C, and C++ compilers and program development tools on CPUs and NVIDIA GPUs, including information about parallelization and optimization.
HPC Compilers Reference Guide: This manual includes reference information for using the NVIDIA HPC compilers and program development tools.

C++ Parallel Algorithms: C++ 17 Parallel Algorithms introduce parallel and vector concurrency through execution policies and are supported in the NVC++ compiler.
CUDA C++ Programming Guide: A comprehensive guide to understanding and developing and optimizing code in the CUDA C++ programming environment.
CUDA Fortran Programming Guide: This guide describes how to program with CUDA Fortran, a small set of extensions to Fortran that supports and is built upon the NVIDIA CUDA programming model. CUDA Fortran is available on a variety of 64-bit operating systems for both x86 and Arm hardware platforms. CUDA Fortran includes runtime APIs and programming examples.
Using OpenACC: This section describes directive-based OpenACC programming in which compiler directives are used to specify regions of code in Fortran, C and C++ programs to be offloaded from a host CPU to an NVIDIA GPU.
Using OpenMP: OpenMP is a set of compiler directives, an applications programming interface (API), and a set of environment variables for specifying parallel execution in Fortran, C++ and C programs.

HPC Compiler Support Services Quick Start Guide: This guide provides minimal instructions for accessing NVIDIA portals as well as downloading and installing the supported software.
HPC Compiler Support Services Supplement: These are the terms and conditions of the optional NVIDIA HPC Compilers Support Services offering.

HPC Compilers Documentation Archive: This Archives document provides access to previously released documentation for PGI compilers back to 2010.
