DescriptionExtracting performance from simulations with complex information dependencies
on massively parallel computers requires the computational work to be evenly
distributed across the processing resources while maintaining low
communication costs.
Plasma simulations using a particle-in-cell method and computational fluid
dynamics using unstructured mesh-based finite element and volume
methods present three distinct distribution requirements.
To meet these needs, we present EnGPar's diffusive partition improvement
method.
An initial demonstration of EnGPar's particle distribution improvement is
provided along with fluid dynamics mesh partition improvement results on up to
512Ki processes on an IBM BlueGene/Q.
