Abstract
A liveness-based memory allocation module operating so that a program thread invoking the memory allocation module is provided with an allocation of memory including a reserve of free heap slots beyond the immediate requirements of the invoking thread. The module receives a parameter representing a thread execution window from an invoking thread; calculates a liveness metric based upon the parameter; calculates a reserve of memory to be passed to the invoking thread based upon the parameter; returns a block of memory corresponding to the calculated reserve of memory. Equations, algorithms, and sampling strategies for calculating liveness metrics are disclosed, as well as a method for adaptive control of the module to achieve a balance between memory efficiency and potential contention as specified by a single control parameter.
