DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: Various patterns form during directional solidification of ternary eutectic alloys.=0AThese macroscopic patterns strongly influences the material properties.=0ATo study the influence of the material and process parameters for a wide range of ternary alloys during solidification, simulations are conducted to gain new insights.=0AIn this poster, we present the results of massive parallel phase-field simulations on up to 262144 cores, based on the HPC framework waLBerla.=0AResults of optimization techniques are shown, starting from the model up to the code level, including buffering strategies and vectorization.=0AThe approach comprises systematic node level performance engineering and gains in a speedup of factor 80 compared to the original code.=0AExcellent weak scaling results on the currently largest German supercomputers, SuperMUC, Hornet and Juqueen, are presented. =0ANovel methods like principle component analysis and graph based approaches are applied to compare the computed microstructural patterns with experimental Al-Ag-Cu micrographs.
