Detailed 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;

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