Abstract: Disclosed herein are system, method, and computer program product (computer-readable storage medium) embodiments for implementing memory management via dynamic tiering pools. An embodiment operates by initializing a first memory pool of a first tier, and invoking first and second function calls to allocate memory to the first memory pool. Responsive to these function calls, an OS may allocate differently-sized memory elements for attachment to the first memory pool, from a memory free store managed by the OS. A second memory pool, of a second tier, may be further initialized, and a third function call may be invoked, to allocate memory to the second memory pool. Here, in response to the third function call, the first memory pool may reallocate the second memory element from the first memory pool for attachment to the second memory pool.
