Systems, apparatuses, and methods for employing system probe filter aware last level cache insertion bypassing policies are disclosed. A system includes a plurality of processing nodes, a probe filter, and a shared cache. The probe filter monitors a rate of recall probes that are generated, and if the rate is greater than a first threshold, then the system initiates a cache partitioning and monitoring phase for the shared cache. Accordingly, the cache is partitioned into two portions. If the hit rate of a first portion is greater than a second threshold, then a second portion will have a non-bypass insertion policy since the cache is relatively useful in this scenario. However, if the hit rate of the first portion is less than or equal to the second threshold, then the second portion will have a bypass insertion policy since the cache is less useful in this case.

The present application discloses a cache access method and an associated graph neural network system. The graph neural network processor is used for performing computation upon a graph neural network. The graph neural network is stored in the memory in compressed sparse row format. The method includes: receiving an address corresponding to a node of the graph neural network and a type of the address; in response to the type is one of a first type or a second type, performing lookup by comparing the address with a tag field of a degree lookup table to at least obtain a degree of the node; determining whether the degree is greater than a predetermined value to obtain a determination result; and determining whether to perform lookup on a region of the cache corresponding to the type according to the determination result.

Disclosed embodiments relate to a dNap architecture that accurately transitions cache lines to full power state before an access to them. This ensures that there are no additional delays due to waking up drowsy lines. Only cache lines that are determined by the DMC to be accessed in the immediate future are fully powered while others are put in drowsy mode. As a result, we are able to significantly reduce leakage power with no cache performance degradation and minimal hardware overhead, especially at higher associativities. Up to 92% static/Leakage power savings are accomplished with minimal hardware overhead and no performance tradeoff.

Secure distributed storage and transmission of electronic content is provided over at least one communication network. At least one data file is received and parsed into a plurality of segments, wherein each one of the segments has a respective size. Thereafter, each of the plurality of segments is divided into a plurality of slices, wherein each one of the slices has a respective size. A plurality of data chunks are encoded, each data chunk comprising a portion of at least two of the slices, wherein no portion comprises an entire slice. The data chunks are packaged with at least metadata, and each of the packages is assigned to respective remote storage nodes. Each of the packages is transmitted to the respectively assigned remote storage node.

A memory controller includes a buffer memory configured to store first meta data and second meta data having a different type from the first meta data, and a cache memory including first and second dedicated areas. The first meta data is cached in the first dedicated area and the second meta data is cached in the second dedicated area.

A volatile storage component operatively connected to a node, that includes a volatile storage device, a power source, and a plurality of processor cores, where, a first processor core of the plurality of processor cores is executing a volatile storage firmware, and a second processor core of the plurality of processor cores is executing a volatile storage operating system.

Embodiments of a multitenant content server that employs embodiments of a database architecture for use in multitenant environments that includes a global partition and a tenant partition for each tenant. These partitions can be accessed using sessions corresponding to the partitions and interfaces associated with the tenants.

Resources of an electronic device are partitioned into a plurality of resource portions to be utilized by a plurality of clients. Each resource portion is assigned to a respective client, has a respective partition identifier (ID), and corresponds to a plurality of memory bandwidth usage states tracked for a plurality of memory blocks. For each resource portion, each of the memory bandwidth usage states is associated with a respective memory block and indicates at least how much of a memory access bandwidth assigned to the respective partition ID to access the respective memory block is used. A usage level is determined for each resource partition based on the memory bandwidth usage states, and applied to adjust a credit count. When the credit count is adjusted beyond a request issue threshold, a next data access request is issued from a memory access request queue for the respective partition ID.

Methods, systems, and devices for a split cache for address mapping data are described. A memory system may include a cache (e.g., including a first and second portion) for storing data that indicates a mapping between logical addresses associated with a host system and physical addresses of the memory system. The memory system may store data (e.g., the address mapping data) within the first portion of the cache. Additionally, the memory system may store an indication of whether the data is used for any access operations during a duration that the data is stored in the first portion of the cache. The memory system may transfer subsets of the data to the second portion of the cache if they are used for access operations during the duration.
