Concurrent array-based queue

A system for implementing a queue, the system comprising:

• a memory and a controller, the system configured to perform a method comprising:
• configuring, in the memory, metadata of an array-based queue, the array-based queue located in the memory, wherein configuring comprises:
• defining, in the metadata, an array start location in the memory for the array-based queue;
• defining, in the metadata, an array size for the array-based queue;
• defining, in the metadata, a queue top for the array-based queue;
• and
• defining, in the metadata, a queue bottom for the array-based queue;
• and
• serving, by the controller, a request for an operation on the queue, the request providing the location, in the memory, of the metadata of the queue.

A computer program product for implementing an array-based queue in memory of a memory system, the memory system including a controller, the computer program product comprising:

• a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• configuring, in the memory, metadata of the array-based queue, wherein configuring comprises:
• defining, in the metadata, an array start location in the memory for the array-based queue;
• defining, in the metadata, an array size for the array-based queue;
• defining, in the metadata, a queue top for the array-based queue;
• and
• defining, in the metadata, a queue bottom for the array-based queue;
• and
• serving, by a controller, a request for an operation on the queue, the request providing the location, in the memory, of the metadata of the queue.
