In the GAMG control dictionary:

Usage

Example of manual processor agglomeration

processorAgglomeration
{
    agglomerator    manual;

    // List of level + list of processor clusters
    //
    // Each cluster of processor is specified as a list of IDs which are
    // merged 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)
            )
        )
    );
