摘要： Various approaches for configuring interleaving in a memory pool used in an edge computing arrangement, including with the use of infrastructure processing units (IPUs) and similar networked processing units, are disclosed. An example system may discover and map disaggregated memory resources at respective compute locations connected to each another via at least one interconnect. The system may identify workload requirements for use of the compute locations by respective workloads, for workloads provided by client devices to the compute locations. The system may determine an interleaving arrangement for a memory pool that fulfills the workload requirements, to use the interleaving arrangement to distribute data for the respective workloads among the disaggregated memory resources. The system may configure the memory pool for use by the client devices of the network, as the memory pool causes the disaggregated memory resources to host data based on the interleaving arrangement.

摘要： The present disclosure is generally related to edge computing technologies (ECTs), communications networking, network slicing, and in particular, to techniques and technologies for providing flow-specific network slices. In particular, the present disclosure describes mechanisms that expand existing end-to-end architectures in order to include quality of service and monitoring mechanisms that connect network slicing technologies with infrastructure and/or network data center quality of service provider domains. The described mechanisms provide data center bridging to enable network, edge computing, and cloud computing domains.

摘要： The platform data aging for adaptive memory scaling described herein provides technical solutions for technical problems facing power management for electronic device processors. Technical solutions described herein include improved processor power management based on a memory region life-cycle (e.g., short-lived, long-lived, static). In an example, a short-term memory request is allocated to a short-term memory region, and that short-term memory region is powered down upon expiration of the lifetime of all short-term memory requests on the short-term memory region. Multiple memory regions may be scaled down (e.g., shut down) or scaled up based on demands for memory capacity and bandwidth.

摘要： Technologies for quality of service based throttling in a fabric architecture include a network node of a plurality of network nodes interconnected across the fabric architecture via an interconnect fabric. The network node includes a host fabric interface (HFI) configured to facilitate the transmission of data to/from the network node, monitor quality of service levels of resources of the network node used to process and transmit the data, and detect a throttling condition based on a result of the monitored quality of service levels. The HFI is further configured to generate and transmit a throttling message to one or more of the interconnected network nodes in response to having detected a throttling condition. The HFI is additionally configured to receive a throttling message from another of the network nodes and perform a throttling action on one or more of the resources based on the received throttling message. Other embodiments are described herein.

摘要： Methods and apparatus for platform ambient data management schemes for tiered architectures. A platform including one or more CPUs coupled to multiple tiers of memory comprising various types of DIMMs (e.g., DRAM, hybrid, DCPMM) is powered by a battery subsystem receiving input energy harvested from one or more green energy sources. Energy threshold conditions are detected, and associated memory reconfiguration is performed. The memory reconfiguration may include but is not limited to copying data between DIMMs (or memory ranks on the DIMMS in the same tier, copying data between a first type of memory to a second type of memory on a hybrid DIMM, and flushing dirty lines in a DIMM in a first memory tier being used as a cache for a second memory tier. Following data copy and flushing operations, the DIMMs and/or their memory devices are powered down and/or deactivated. In one aspect, machine learning models trained on historical data are employed to project harvested energy levels that are used in detecting energy threshold conditions.

摘要： A device of a service coordinating entity includes communications circuitry to communicate with a plurality of access networks via a corresponding plurality of network function virtualization (NFV) instances, processing circuitry, and a memory device. The processing circuitry is to perform operations to monitor stored performance metrics for the plurality of NFV instances. Each of the NFV instances is instantiated by a corresponding scheduler of a plurality of schedulers on a virtualization infrastructure of the service coordinating entity. A plurality of stored threshold metrics is retrieved, indicating a desired level for each of the plurality of performance metrics. A threshold condition is detected for at least one of the performance metrics for an NFV instance of the plurality of NFV instances, based on the retrieved plurality of threshold metrics. A hardware resource used by the NFV instance to communicate with an access network is adjusted based on the detected threshold condition.

摘要： 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.

摘要： A method of fabricating a micromirror is disclosed. Initially, a set of coarse features is formed in a low-temperature oxide (LTO) layer deposited on a front side of a wafer. A set of fine features is then formed in a photosensitive material layer deposited on top of the LTO layer, and the fine features are constrained laterally within the coarse features. Next, a portion of the LTO layer is removed to align the width of the coarse features with the width of the fine features. The first silicon dioxide layer and the first and second silicon device layers are subsequently etched to form stator comb fingers and rotor comb fingers. Finally, a rotatable mirror is formed by removing a portion of the substrate on a back side of the wafer, and the silicon dioxide layers from the front and back sides of the wafer.

摘要： An optical-encoded force sensor is disclosed. The optical-encoded force sensor includes a cantilever probe having a probe tip, a set of reflective phase gratings and multiple nano-photonic displacement sensors. The reflective phase gratings are mechanically coupled to the cantilever probe, and the nano-photonic displacement sensors are mechanically coupled to the reflective phase gratings. In response to a load being applied to the probe tip, the reflective phase gratings can be compressed such that a diffraction order of the reflective phase gratings changes according to the force of the applied load.
