Abstract: Systems and methods for updating remote memory side caches in a multi-GPU configuration are disclosed herein. In one embodiment, a graphics processor for a multi-tile architecture includes a first graphics processing unit (GPU) having a first memory, a first memory side cache memory, a first communication fabric, and a first memory management unit (MMU). The graphics processor includes a second graphics processing unit (GPU) having a second memory, a second memory side cache memory, a second memory management unit (MMU), and a second communication fabric that is communicatively coupled to the first communication fabric. The first MMU is configured to control memory requests for the first memory, to update content in the first memory, to update content in the first memory side cache memory, and to determine whether to update the content in the second memory side cache memory.

Abstract: Apparatus and method for improved cache utilization and efficiency on a many-core processor. An apparatus comprising: a plurality of execution units to generate cache access requests responsive to executing instructions; a pending request queue to store pending cache access requests generated by the execution units; pending queue management circuitry to compare a current cache access request with entries in the pending request queue to determine whether the current cache access request can be merged with an entry in the pending request queue and, if so, to merge the current cache access request with the entry.

Abstract: A mechanism is described to facilitate microcontroller-based flexible thread scheduling launching in computing environments. An apparatus of embodiments, as described herein, includes facilitating a graphics processor hosting a microcontroller having a thread scheduling unit, and detection and observation logic to detect a scheduling algorithm associated with an application at the apparatus. The apparatus may further include reading and dispatching logic to facilitate the microcontroller to prepare a flexible dispatch routine based on the scheduling algorithm. The apparatus may further include scheduling and launching logic to facilitate the thread scheduling unit to dynamically schedule and launch threads based on the flexible dispatch routine, where the threads are hosted by the graphics processor.

Abstract: Embodiments described herein provide a graphics, media, and compute device having a tiled architecture composed of a number of tiles of smaller graphics devices. The work distribution infrastructure for such device enables the distribution of workloads across multiple tiles of the device. Work items can be submitted to any one or more of the multiple tiles, with workloads able to span multiple tiles. Additionally, upon completion of a work item, graphics, media, and/or compute engines within the device can readily acquire new work items for execution with minimal latency.

Abstract: Embodiments described herein provide a general purpose graphics processor comprising a plurality of tiles, each tile of the plurality of tiles comprising at least one execution unit, a local cache, and a cache control unit, and a high bandwidth memory communicatively coupled to the plurality of tiles, wherein the high bandwidth memory is shared between the plurality of tiles. The cache control unit is to implement a partial write management protocol to receive a partial write operation directed to a cache line in the local cache, the partial write operation comprising write data, write the data associated with the partial write operation to the local cache when the cache line is in a modified state, and forward the write data associated with the partial write operation to the high bandwidth memory when the partial write operation triggers a cache miss or when the cache line is in an exclusive state or a shared state. Other embodiments may be described and claimed.
