Abstract: Apparatus and methods implementing a hardware queue management device for reducing inter-core data transfer overhead by offloading request management and data coherency tasks from the CPU cores. The apparatus include multi-core processors, a shared L3 or last-level cache (“LLC”), and a hardware queue management device to receive, store, and process inter-core data transfer requests. The hardware queue management device further comprises a resource management system to control the rate in which the cores may submit requests to reduce core stalls and dropped requests. Additionally, software instructions are introduced to optimize communication between the cores and the queue management device.

Abstract: Apparatus and method for multi-core dynamically-balanced task processing while maintaining task order in chip multiprocessor platforms. One embodiment of an apparatus includes: a distribution circuitry to distribute, among a plurality of processing units, tasks from one or more workflows; a history list to track all tasks distributed by the distribution circuitry; an ordering queue to store one or more sub-tasks received from a first processing unit as a result of the first processing unit processing a first task; and wherein, responsive to a detection that all sub-tasks of the first task have been received and that the first task is the oldest task for a given parent workflow tracked by the history list, all sub-tasks associated with the first task are to be placed in a replay queue to be replayed in the order in which each sub-task was received.

Abstract: Technologies for a distributed hardware queue manager include a compute device having a processor. The processor includes two or more hardware queue managers as well as two or more processor cores. Each processor core can enqueue or dequeue data from the hardware queue manager. Each hardware queue manager can be configured to contain several queue data structures. In some embodiments, the queues are addressed by the processor cores using virtual queue addresses, which are translated into physical queue addresses for accessing the corresponding hardware queue manager. The virtual queues can be moved from one physical queue in one hardware queue manager to a different physical queue in a different physical queue manager without changing the virtual address of the virtual queue.
