Abstract Scope |
Simulating the entire process of metallic additive manufacturing (AM) is making significant strides towards helping understand the structures and concomitant properties in experimental AM parts and, eventually, increased use in application. Cellular automata (CA) is a crucial step in understanding process-microstructure-property relations in AM, where we have developed the ExaCA application with a sparse representation of the time-temperature history from process models to drive simulation of grain-scale microstructures that can be used to determine constitutive properties. We focus specifically on the computational aspects of running and improving ExaCA, particularly on current and future exascale architectures, including multi-core CPUs and GPUs. Important points of emphasis are writing code in a performance portable manner with the Kokkos programming model and considering optimizations which fit properly within the larger ExaAM (Exascale Computing Project for AM) AM build workflow as described above. |
