Class
Foam::masterCoarsestGAMGProcAgglomeration
Description
Processor agglomeration of GAMGAgglomerations.
- by default agglomerates onto the master processor
- optionally have multiple masters through the nProcessorsPerMaster
parameter. e.g.
p
{
solver GAMG;
tolerance 1e-06;
relTol 0.1;
smoother GaussSeidel;
nCellsInCoarsestLevel 10;
processorAgglomerator masterCoarsest;
// Groups of 32 cores get combined so each 'master' gets
// (roughly) 32*nCellsInCoarsestLevel cells.
nProcessorsPerMaster 32;
// Alternative : specify number of (equi-distributed) masters
nMasters 2;
}
