Layered Concurrency Management

One or more non-transitory computer-readable media storing program instructions that, when executed by one or more hardware processors, cause performance of operations comprising:

• embedding a first value into a first set of one or more bits in a first pointer that refers to a first object comprised within a runtime memory area, the runtime memory area comprising (a) a first set of one or more objects that are associated with a first policy for executing requests and (b) a second set of one or more objects that are associated with a second policy for executing requests, wherein the first value indicates that the first object is either (a) comprised within the first set of one or more objects or (b) comprised within the second set of one or more objects;
• receiving a request to manipulate a field of the first object from a program instance that is being executed by a thread, wherein the request is attempting to either (a) load a second pointer from the field or (b) store the second pointer to the field;
• responsive to receiving the request, executing, by the thread, a barrier corresponding to the request, wherein executing the barrier comprises:
• based, at least in part, on the first value embedded within the first set of one or more bits of the first pointer to determine if the first object is comprised within (a) the first set of one or more objects associated with the first policy for executing requests or (b) the second set of one or more objects associated with the second policy for executing requests;
• and
• performing one of:
• (a) based, at least in part, on determining that the first object is comprised within the first set of one or more objects, applying the first policy for executing requests to the request;
• or
• (b) based, at least in part, on determining that the first object is comprised within the second set of one or more objects, applying the second policy for executing requests to the request.

A system comprising:

• one or more hardware processors;
• one or more non-transitory computer-readable media;
• and
• program instructions stored on the one or more non-transitory computer-readable media which, when executed by the one or more hardware processors, cause the system to perform operations comprising:
• embedding a first value into a first set of one or more bits in a first pointer that refers to a first object comprised within a runtime memory area, the runtime memory area comprising (a) a first set of one or more objects that are associated with a first policy for executing requests and (b) a second set of one or more objects that are associated with a second policy for executing requests, wherein the first value indicates that the first object is either (a) comprised within the first set of one or more objects or (b) comprised within the second set of one or more objects;
• receiving a request to manipulate a field of the first object from a program instance that is being executed by a thread, wherein the request is attempting to either (a) load a second pointer from the field or (b) store the second pointer to the field;
• responsive to receiving the request, executing, by the thread, a barrier corresponding to the request, wherein executing the barrier comprises:
• based, at least in part, on the first value embedded within the first set of one or more bits of the first pointer to determine if the first object is comprised within (a) the first set of one or more objects associated with the first policy for executing requests or (b) the second set of one or more objects associated with the second policy for executing requests;
• and
• performing one of:
• (a) based, at least in part, on determining that the first object is comprised within the first set of one or more objects, applying the first policy for executing requests to the request;
• or
• (b) based, at least in part, on determining that the first object is comprised within the second set of one or more objects, applying the second policy for executing requests to the request.
