LinearMap class
Contents
Charm++ array map for initial placement of array elements in linear fashion
The map object is used by the Charm++ array manager to determine the "home" PE of each element. The home PE is the PE upon which the array element is initially placed, which will retain responsibility for maintaining the location of the element.
