Detailed Description

Manual processor agglomeration of GAMGAgglomerations.

In the GAMG control dictionary:

processorAgglomerator manual; List of level+procagglomeration where procagglomeration is a set of labelLists. Each labelList is a cluster of processor which gets combined onto the first element in the list. processorAgglomeration ( ( 3 //at level 3 ( (0 1) //coarse 0 from 0,1 (and moved onto 0) (3 2) //coarse 1 from 2,3 (and moved onto 3) ) ) ( 6 //at level6 ( (0 1) //coarse 0 from 0,1 (and moved onto 0) ) ) );
