mail is a two-dimensional-grid-abstraction class. A grid naming abstraction is attached to the process list; each process is specified by a pair (e.g., in the PO Box). Through inheritance, row and column mailers are defined in each process as the appropriate subsets of the two-dimensional grid. This class has received the most extensive use because of the natural application to linear algebra and related computations.

Class-specific primitives for G2-Class mail have been defined for both higher efficiency and better abstraction. Small-g calls require mailer specification while big-G calls do not, analogous to the y- and Y-type calls defined generically above.
