OpenACC
A directive-based parallel computing programming standard used to offload computational tasks to accelerators such as GPUs, supporting Fortran and C/C++.
Timeline (last 90 days)
The Fortran community adapts to GPUs and AI accelerator cards through solutions such as OpenMP, OpenACC and CUDA Fortran.
OpenACC is a high-level directive set where developers annotate code with #pragma directives to instruct the compiler to automatically generate GPU code, offering a low migration barrier and strong code portability.
For 250,000 lines of Fortran code, OpenACC is typically the preferred starting point, with CUDA used to optimize performance-critical sections after a successful migration.
