SHARED AND MANAGED MEMORY UNIFIED ACCESS

摘要

A managed memory in which multiple computing entities each have a corresponding entity-specific portion that is subject to garbage collection. An immutable buffer is located outside of managed memory. For a given computing entity, the corresponding managed memory portion contains entity-specific objects that can be accessed by a specific computing entity, but not by the other multiple computing entities. For one or more of the entity-specific managed memory portions, the portion also includes a reference to shared memory, such as an immutable buffer. The reference is structured to be ignored by the garbage collector, though the reference may appear just as a normal object in the managed memory portion. Thus, a unified memory access model is made possible in which the methods for a computing entity to access a regular object in managed memory is similar to how the computing entity accesses shared memory.

1. A system comprising:
a managed memory have a plurality of managed memory portions, each corresponding to a managed computing entity; an immutable buffer located outside of the managed memory, wherein a particular managed memory portion of the plurality of managed memory portions includes one or more garbage collectable objects that are accessible to the corresponding particular managed computing entity, but not to the other computing entities, the particular managed memory portion also including one or more references to the immutable buffer; and a garbage collection component configured to manage the one or more garbage collectable objects in the particular managed memory portion, but also configured to not perform any actions on the one or more references to the immutable buffer.
