High performance additive manufacturing phase field simulation: Fortran Do Concurrent vs OpenMP

Abstract

Standard language parallelism is an alternate way to achieve the parallel performance of the code without using external application processing interface (API). In this work, we present the Fortran Do Concurrent standard language parallel feature for additive manufacturing. We developed an open-source AMSimulator application and have implemented OpenMP and Fortran Do Concurrent in the phase field simulation. Performance has been measured across various platforms like Windows 10 and Linux and open-source compilers with Intel and NVIDIA. We found that using standard language parallel features, the same performance can be achieved without the need of external API. This high-performance approach is useful for code development and portability across various platforms.
