US 7,743,222 B2 · Methods, systems, and media for managing dynamic storage

Abstract

Methods, systems, and media for managing dynamic memory are disclosed. Embodiments may disclose identifying nodes with having memory for dynamic storage, and reserving a portion of the memory from the identified nodes for a heap pool. After generating a heap pool, embodiments may allocate dynamic storage from the heap pool to tasks received that are associated with one of the identified nodes. More specifically, embodiments identify the node or home node associated with the task, the amount of dynamic storage requested by the task, and create a heap object in the node associated with the task to provide the requested dynamic storage. Some embodiments involve de-allocating the dynamic storage assigned to the task upon receipt of an indication that the task is complete and the dynamic storage is no longer needed for the task. Several of such embodiments return the de-allocated dynamic storage to the heap pool for reuse.

Dependent claims

An apparatus for managing memory, the apparatus comprising:

a heap reserver to identify a plurality of nodes each having a respective processor and respective memory for heap storage and to reserve the heap storage from the memories of the nodes;
a heap pool coupled with the heap reserver to maintain reservations of the heap storage, the heap pool comprising:
a description of nodes having memory for heap storage;
a description of available memory for heap storage;
a description of memory being used for heap storage;
and
control information for managing heaps;
and
a dynamic storage manager coupled with the heap pool to identify at least one node of the plurality of nodes associated with a request for dynamic storage, the association between the request and the at least one node being defined in a task node association data structure of an application issuing the request, and allocate a portion of the heap storage from the heap pool to the request based upon the association between the request and the at least one node as defined by the task node association data structure.
