Optional CPU load caching can be switched-on for Lagrangian cloud tracking
and/or chemistry integration using the new cpuLoad switch in the cloudProperties
or chemistryProperties dictionary files respectively and used for
multi-constraint load-balancing by the fvMeshDistributorsLoadBalancer specified
in the dynamicMeshDict file
distributor
{
type loadBalancer;
libs ("libfvMeshDistributors.so");
multiConstraint true;
redistributionInterval 10;
}
which used the distributor specified in the decomposeParDict file, e.g.
numberOfSubdomains 12;
decomposer simple;
distributor zoltan;
libs ("libzoltanDecomp.so");
simpleCoeffs
{
n (2 2 3);
}
zoltanCoeffs
{
lb_method rcb;
}
The incompressibleDenseParticleFluid/cyclone case has been updated to
demonstrate this new functionality and shows a speedup ~50% using the Zoltan RCB
multi-constraint distributor. The multicomponentFluid/counterFlowFlame2D_GRI
case has also been updated to use the new cpuLoad switch.
