In connection with an access of content from a cache, a snoop request can be sent to one or more remote cache devices to determine if any other cache has a copy of the content. A link between the cache and the remote cache devices can include a snoop bypass device. The snoop bypass device can monitor content cached by the one or more remote devices on a cache line or coarser granularity. The snoop bypass device can respond to the snoop request with a negative indication based on a coarser granularity tracking of content of the one or more remote cache devices.

A chiplet system includes a central processing unit (CPU) communicably coupled to a first GPU chiplet of a GPU chiplet array. The GPU chiplet array includes the first GPU chiplet communicably coupled to the CPU via a bus and a second GPU chiplet communicably coupled to the first GPU chiplet via an active bridge chiplet. The active bridge chiplet is an active silicon die that bridges GPU chiplets and allows partitioning of systems-on-a-chip (SoC) functionality into smaller functional chiplet groupings.

In an example, an apparatus comprises a plurality of execution units, and a cache memory communicatively coupled to the plurality of execution units, wherein the cache memory is structured into a plurality of sectors, wherein each sector in the plurality of sectors comprises at least two cache lines. Other embodiments are also disclosed and claimed.

A method and apparatus for cache management and eviction polices using unsupervised reinforcement learning schemes is disclosed.

A memory device for storing data comprises a memory bank comprising a plurality of addressable memory cells, wherein the memory bank is divided into a plurality of segments. The memory device also comprises a cache memory operable for storing a second plurality of data words, wherein further each data word of the second plurality of data words is either awaiting write verification or is to be re-written into the memory bank. The cache memory is divided into a plurality of primary segments, wherein each primary segment of the cache memory is direct mapped to a corresponding segment of the plurality of segments of the memory bank, wherein each primary segment of the plurality of primary segments of the cache memory is sub-divided into a plurality of secondary segments, and each of the plurality of secondary segments comprises at least one counter for tracking a number of valid entries stored therein.

Technologies for switching network traffic include a network switch. The network switch includes one or more processors and communication circuitry coupled to the one or more processors. The communication circuity is capable of switching network traffic of multiple link layer protocols. Additionally, the network switch includes one or more memory devices storing instructions that, when executed, cause the network switch to receive, with the communication circuitry through an optical connection, network traffic to be forwarded, and determine a link layer protocol of the received network traffic. The instructions additionally cause the network switch to forward the network traffic as a function of the determined link layer protocol. Other embodiments are also described and claimed.

Exemplary methods, apparatuses, and systems include detecting an operation to write dirty data to a cache. The cache is divided into a plurality of channels. In response to the operation, the dirty data is written to a first cache line in the cache, the first cache line being accessed via a first channel. Additionally, a redundant copy of the dirty data is written to a second cache line in the cache. The second cache line serves as a redundant write buffer and is accessed via a second channel, the first and second channels differing from one another. A metadata entry for the second cache line is updated to reference a location of the dirty data in the first cache line.
