Compiler

Description

Supports

nvc

C11 compiler for NVIDIA GPUs and AMD, Intel, OpenPOWER, and Arm CPUs. It invokes the C compiler, assembler, and linker for the target processors with options derived from its command line arguments.

  • ISO C11

  • GPU programming with OpenACC

  • Multicore CPU programming with OpenACC and OpenMP.

nvc++

C++17 compiler for NVIDIA GPUs and Intel CPUs. It invokes the C++ compiler, assembler, and linker for the target processors with options derived from its command line arguments.

  • ISO C++17

  • GPU programming with C++17 parallel algorithms (pSTL) and OpenACC

  • Multicore CPU programming with OpenACC and OpenMP.

nvfortran

Fortran compiler for NVIDIA GPUs and Intel CPUs. It invokes the Fortran compiler, assembler, and linker for the target processors with options derived from its command line arguments.

  • ISO Fortran 2003 and many features of ISO Fortran 2008

  • GPU programming with CUDA Fortran and OpenACC

  • Multicore CPU programming with OpenACC and OpenMP.

nvcc

CUDA C and CUDA C++ compiler driver for NVIDIA GPUs. nvcc accepts a range of conventional compiler options, such as for defining macros and include/library paths, and for steering the compilation process. nvcc produces optimized code for NVIDIA GPUs and drives a supported host compiler for AMD, Intel, OpenPOWER, and Arm CPUs.

Getting Started:

The installed SDKs do come with a folder of examples which you can take a copy of. For example, on Beartooth:

Code Block
[]$ cp -R /apps/u/opt/compilers/nvhpc/22.11/Linux_x86_64/22.11/examples .

Note: When making the various examples, they typically build and run the code. So, in some cases, unless you have created an interactive session with multiple cores (for MPI) or requested a GPU, although the code will build and it will error when run.
