Abstract

A generalization of the buddy system for storage allocation is described. The set of permitted block sizes {SIZEi}ni=0 must satisfy the condition SIZEi = SIZEi-1 + SIZEi-k(i) where k may be any meaningful integral-valued function. This makes it possible to force logical storage blocks to coincide with physical storage blocks, such as tracks and cylinders.
