Processor agglomeration of GAMGAgglomerations.
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;
Restart local agglomeration after processor agglomeration. Used as nCellsInCoarsestLevel. Only applicable for pair-wise local agglomeration methods. nCellsInMasterLevel 1; }
