There is provided mechanisms for initiating writing data of a pending memory write on a host computer. A method comprises monitoring pending memory writes for a non-volatile memory write indicator (NVMWI). The NVMWI is either set or not set. The method comprises initiating writing of the data of the pending memory write. Writing of the data is initiated to both a non-volatile memory (NVM) and a volatile memory (VM) when the NVMWI for the pending memory write is set. Writing of the data otherwise is initiated only to the VM.

Snapshotting pending memory writes using non-volatile memory

A method performed by a coordinating entity in a disaggregated data center architecture wherein computing resources are separated in discrete resource pools and associated together to represent a functional server. The coordinating entity obtains a setup of processor cores that are coupled logically as the functional server, and determines an index indicating an identity of a cache coherency domain based on the obtained setup of processor cores. The coordinating entity further configures one or more communicating entities associated with the obtained setup of processor cores, to use the determined index when handling updated cache related data.

Network entities and methods performed therein for handling cache coherency

There is provided mechanisms for snapshotting data of a host application. A method is performed by a field-programmable gate array (FPGA). The method comprises snooping a cache coherent interconnect of a host computer on which the host application is running. The cache coherent interconnect is snooped for dirty cache lines, each dirty cache line having an address. The method comprises writing, only when the address of any of the dirty cache lines has a match in a snapshot address table, data of that dirty cache line to a non-volatile memory.

Snapshotting data of a host application

A system and method to distribute traffic flows among a plurality of applications in a data center system. An apparatus is operable with a plurality of applications connected through a programmable switch and is configured to select traffic flows to ones of the plurality of applications. The apparatus is also configured to monitor and collect statistics for the traffic flows to determine rule level statistics, and move at least one traffic flow of the traffic flows from a network interface to a different network interface based on the rule level statistics.

System and method to distribute traffic flows among a plurality of applications in a data center system

Methods and apparatus are disclosed, including an example of a method of determining a distance between a first point and a second point. The method includes manipulating quantum states of at least first and second qubits of a quantum computing device based on a test vector representing the first point and a training vector representing the second point, performing quantum interference between the test vector and the training vector, performing a measurement on one or more of the qubits to determine the distance, and determining the distance from the measurement.

Determining a distance

A method for offloading services of a sewer application in a network system. The method includes receiving, by a first in-network computation offload instance, a first request packet from a client application, wherein the first request packet includes a first application payload for processing by the server application; generating, by the first instance, a modified request packet that includes the first application payload and first offload information that describes the first instance for use by the server application in coordinating offloading processing to one or more in-network computation offload instances; and transmitting, by the first instance, the modified request packet to the next device in the traffic flow between the client application and the server application, wherein the next device is either (1) a second in-network computation offload instance in the traffic flow between the client application and the server application or (2) the sewer application.
