Overview of CUDA Fortran supported by XL Fortran

CUDA is a parallel programming model and software environment to exploit the NVIDIA GPUs. It provides programmers with a set of instructions that enables GPU acceleration for data-parallel computations. You can increase computing performance of many applications by using CUDA directly or by linking to GPU-accelerated libraries.

IBM® XL Fortran for Linux, V16.1 supports the CUDA Fortran programming model, which is a subset of the CUDA constructs to exploit the NVIDIA GPUs. You can use the commonly used subset of CUDA Fortran that is provided by IBM XL Fortran for Linux, V16.1 to offload computations to the NVIDIA GPUs.
