Abstract: Methods and systems may provide for receiving a request to perform an atomic operation and adding the atomic operation to an execution pipeline of an arithmetic logic unit (ALU) for one or more pending atomic operations if the one or more pending atomic operations are associated with a memory location identified in the request. Additionally, at least a portion of the execution pipeline may bypass the memory location. In one example, adding the atomic operation to the execution pipeline includes populating a linked list with a modification associated with the atomic operation, wherein the linked list is dedicated to the memory location.

Abstract: One embodiment provides circuitry coupled with cache memory and a memory interface, the circuitry to compress compute data at multiple cache line granularity, and a processing resource coupled with the memory interface and the cache memory. The processing resource is configured to perform a general-purpose compute operation on compute data associated with multiple cache lines of the cache memory. The circuitry is configured to compress the compute data before a write of the compute data via the memory interface to the memory bus, in association with a read of the compute data associated with the multiple cache lines via the memory interface, decompress the compute data, and provide the decompressed compute data to the processing resource.
