Abstract: Examples include a processor including a coherency mode indicating one of a directory-based cache coherence protocol and a snoop-based cache coherency protocol, and a caching agent to monitor a bandwidth of reading from and/or writing data to a memory coupled to the processor, to set the coherency mode to the snoop-based cache coherency protocol when the bandwidth exceeds a threshold, and to set the coherency mode to the directory-based cache coherency protocol when the bandwidth does not exceed the threshold.

Abstract: An apparatus comprises a processor to generate, in anticipation of receipt of a read request for data of a data set, a prefetch request to retrieve the data set from a memory device, the prefetch request to comprise at least one parameter indicating a size of the data set. The processor is further to cause transmission of the prefetch request to the memory device and in response to a read request for at least a portion of the data set, request the at least a portion of the data set from a cache storing a copy of the data set, wherein the cache is to store the copy of the data set after the copy is received from the memory device in response to the prefetch request.

Abstract: Persistent caching of memory-side cache content for devices, systems, and methods are disclosed and discussed. In a system including both a volatile memory (VM) and a nonvolatile memory (NVM), both mapped to the system address space, software applications directly access the NVM, and a portion of the VM is used as a memory-side cache (MSC) for the NVM. When power is lost, at least a portion of the MSC cache contents is copied to a storage region in the NVM, which is restored to the MSC upon system reboot.

Abstract: Systems, apparatuses and methods may provide for detecting an issued request in a queue that is shared by a plurality of domains in a memory architecture, wherein the plurality of domains are associated with non-uniform access latencies. Additionally, a destination domain associated with the issued request may be determined. Moreover, a first set of additional requests may be prevented from being issued to the queue if the issued request satisfies an overrepresentation condition with respect to the destination domain and the first set of additional requests are associated with the destination domain. In one example, a second set of additional requests are permitted to be issued to the queue while the first set of additional requests are prevented from being issued to the queue, wherein the second set of additional requests are associated with one or more remaining domains in the plurality of domains.

Abstract: Technologies for providing dynamic persistence of data in edge computing include a device including circuitry configured to determine multiple different logical domains of data storage resources for use in storing data from a client compute device at an edge of a network. Each logical domain has a different set of characteristics. The circuitry is also to configured to receive, from the client compute device, a request to persist data. The request includes a target persistence objective indicative of an objective to be satisfied in the storage of the data. Additionally, the circuitry is configured to select, as a function of the characteristics of the logical domains and the target persistence objective, a logical domain into which to persist the data and provide the data to the selected logical domain.

Abstract: Technologies for providing dynamic selection of edge and local accelerator resources includes a device having circuitry to identify a function of an application to be accelerated, determine one or more properties of an accelerator resource available at the edge of a network where the device is located, and determine one or more properties of an accelerator resource available in the device. Additionally, the circuitry is to determine a set of acceleration selection factors associated with the function, wherein the acceleration factors are indicative of one or more objectives to be satisfied in the acceleration of the function. Further, the circuitry is to select, as a function of the one or more properties of the accelerator resource available at the edge, the one or more properties of the accelerator resource available in the device, and the acceleration selection factors, one or more of the accelerator resources to accelerate the function.

Abstract: Technologies for object-based data consistency in a fabric architecture includes a network switch communicatively coupled to a plurality of computing nodes. The network switch is configured to receive an object read request that includes an object identifier and a data consistency threshold from one of the computing nodes. The network switch is additionally configured to perform a lookup for a value of an object in the cache memory as a function of the object identifier and determine whether a condition of the value of the object violates the data consistency threshold in response to a determination that the lookup successfully returned the value of the object. The network switch is further configured to transmit the value of the object to the computing node in response to a determination that the condition of the value of the object does not violate the data consistency threshold. Other embodiments are described herein.

Abstract: Technologies for network switch based load balancing include a network switch. The network switch is to receive messages, route messages to destination computing devices, receive a request to perform a workload, and receive telemetry data from a plurality of server nodes in communication with the network switch. The telemetry data is indicative of a present load on one or more resources of each server node. The network switch is further to determine channel utilization data for each of the server nodes, select, as a function of the telemetry data and the channel utilization data, one or more of the server nodes to execute the workload, and assign the workload to the selected one or more server nodes. Other embodiments are also described and claimed.
