DescriptionSimulating systems with evolving relational structures
on massively parallel computers require the
computational work to be evenly distributed across the
processing resources throughout the simulation.
Adaptive, unstructured, mesh-based finite element and
finite volume tools best exemplify this need. We present
EnGPar and its diffusive partition improvement method
that accounts for multiple application specified
criteria. EnGPar's performance is compared against its
predecessor, ParMA. Specifically, partition improvement
results are provided on up to 512K processes of the
Argonne Leadership Computing Facility's Mira BlueGene/Q
system.
