Acceleration of a production Solar MHD code with Fortran standard parallelism: From OpenACC to `do concurrent'
Ronald M. Caplan, Miko M. Stulajter, Jon A. Linker
There is growing interest in using standard language constructs for accelerated computing, avoiding the need for (often vendor-specific) external APIs. These constructs hold the po…
Can Fortran's 'do concurrent' replace directives for accelerated computing?
Miko M. Stulajter, Ronald M. Caplan, Jon A. Linker
Recently, there has been growing interest in using standard language constructs (e.g. C++'s Parallel Algorithms and Fortran's do concurrent) for accelerated computing as an alterna…
From MPI to MPI+OpenACC: Conversion of a legacy FORTRAN PCG solver for the spherical Laplace equation
Ronald M. Caplan, Zoran Mikic, Jon A. Linker
A real-world example of adding OpenACC to a legacy MPI FORTRAN Preconditioned Conjugate Gradient code is described, and timing results for multi-node multi-GPU runs are shown. The…
