Welcome to Release 2021 of NVIDIA CUDA Fortran, a small set of extensions to Fortran that supports and is built upon the CUDA computing architecture. GPU designs are optimized for the computations found in graphics Graphic processing units or GPUs have evolved into programmable, highly parallel computational units with very high memoryīandwidth, and tremendous potential for many applications. Rendering, but are general enough to be useful in many data-parallel, compute-intensive programs. NVIDIA introduced CUDA ®, a general purpose parallel programming architecture, with compilers and libraries to support the programming of NVIDIA GPUs.ĬUDA comes with an extended C compiler, here called CUDA C, allowing direct programming of the GPU from a high level language. The programming model supports four key abstractions: cooperating threads organized into thread groups, shared memory andīarrier synchronization within thread groups, and coordinated independent thread groups organized into a grid. Must partition the program into coarse grain blocks that can be executed in parallel. Grain threads, which can cooperate using shared memory and barrier synchronization. Run on any CUDA-enabled GPU, regardless of the number of available processor cores.ĬUDA Fortran includes a Fortran 2003 compiler and tool chain for programming NVIDIA GPUs using Fortran. NVIDIA 2021 includes support for CUDA Fortran on Linux. OpenACC directives-based model and compilers, CUDA Fortran is a lower-level explicit programming model with substantial runtime CUDA Fortran is an analog to NVIDIA's CUDA C compiler. Library components that give expert programmers direct control of all aspects of GPGPU programming.
