Abstract: Provided are systems, methods, and apparatuses for managing memory. The method can include: establishing a connection via an interface, between a host device and a storage device; and transferring data, via the interface, between first memory associated with the host device and second memory associated with the storage device by performing a data operation on the second memory by an application executed by the host, where the storage device includes a processing element that accelerates the data operation by performing at least one offload function on the data operation.

Abstract: Selectively bypassing cache directory lookups for processing-in-memory instructions is described. In one example, a system maintains information describing a status—clean or dirty—of a memory address, where a dirty status indicates that the memory address is modified in a cache and thus different than the memory address as represented in system memory. A processing-in-memory request involving the memory address is assigned a cache directory bypass bit based on the status of the memory address. The cache directory bypass bit for a processing-in-memory request controls whether a cache directory lookup is performed after the processing-in-memory request is issued by a processor core and before the processing-in-memory request is executed by a processing-in-memory component.

In one embodiment, the IPV is selected for a given request based a criticality status of a cache line accessed by the given request. For example, cache lines deemed important or critical for performance reasons may be replaced less frequently via a first IPV, while non-critical cache lines are replaced more frequently via a second IPV.

Abstract: A hierarchical network enables access for a stacked memory system including or more memory dies that each include multiple memory tiles. The processor die includes multiple processing tiles that are stacked with the one or more memory die. The memory tiles that are vertically aligned with a processing tile are directly coupled to the processing tile and comprise the local memory block for the processing tile. The hierarchical network provides access paths for each processing tile to access the processing tile's local memory block, the local memory block coupled to a different processing tile within the same processing die, memory tiles in a different die stack, and memory tiles in a different device. The ratio of memory bandwidth (byte) to floating-point operation (B:F) may improve 50× for accessing the local memory block compared with conventional memory. Additionally, the energy consumed to transfer each bit may be reduced by 10×.
