Abstract: Some embodiments of the present invention are directed to a mode-filtered VCSEL having a multi-layer oxide aperture for high-bandwidth and side-mode suppression. The oxide aperture may include multiple layers having different aluminum fractions configured to increase an SMSR of the VCSEL while maintaining longitudinal confinement. The oxide aperture may be formed from a mirror layer of the VCSEL proximate an active region. The mirror layer may include first epitaxial layers closest to the active region having a first aluminum fraction selected to longitudinally confine the optical field of the VCSEL. The mirror layer may include second epitaxial layers having a second aluminum fraction low enough to prevent substantial oxidation of the second epitaxial layers. Additionally, the mirror layer may include third epitaxial layers having a third aluminum fraction greater than the first and second aluminum fractions. The third epitaxial layers may be oxidized to form the oxide aperture.

Abstract: A system for bandwidth estimation includes an interface and a processor. The interface communicates with a fat-tree (FT) network including multiple switches including (i) leaf switches belonging to a bottom level, (ii) spine switches belonging to a top level and (iii) intermediate switches belonging to one or more intermediate levels. Links connect between selected ones of the switches. The processor is to calculate, for a given level of the FT network that is divided into multiple groups of switches, oversubscription ratios for the respective groups, an oversubscription ratio of a group being indicative of a ratio between (i) a first available bandwidth on the links connecting the switches in the group to a lower level, and (ii) a second available bandwidth on the links connecting the switches in the group to a higher level, and to report a figure of merit of the FT network based on the oversubscription ratios.

Abstract: A peripheral device includes a bus interface and an Address Translation Service (ATS) controller. The bus interface is to communicate over a peripheral bus. The ATS controller is to communicate over the peripheral bus, including sending address translation requests and receiving address translations in response to the address translation requests, to cache at least some of the address translations in one or more Address Translation Caches (ATCs), to estimate one or more statistical properties of the received address translations, and to configure the one or more ATCs based on the one or more statistical properties.

Abstract: Devices, methods, and systems are provided. In one example, a device is described to include a bandwidth-constrained resource and a controller that dynamically allocates a proportional consumption of storage to the bandwidth-constrained resource thereby enabling the bandwidth-constrained resource to provide bandwidth to a consuming entity. The controller may allocate the proportional consumption of the storage to the bandwidth-constrained resource based on a current state of the bandwidth-constrained resource.

Abstract: A system including an array of functional units connected via a two-dimensional mesh network is described. A first functional unit in the array of function units includes a memory device and a processing device, operatively coupled with the memory device, to perform operations including generating a node identifier identifying a second functional unit in the array of functional units, and transmitting, over the two-dimensional mesh network, the node identifier identifying the second functional unit in the array of functional units. The node identifier may include a mesh interface component and a port identifier, and one or more information elements selected from the group consisting of a payload, a target node identifier, a target type identifier, an information type identifier, a linear identifier, and a protocol identifier.

Abstract: A switching device includes ingress ports, egress ports, and switching circuits that connect the ingress ports with the egress ports. The switching device segments data included in a packet received at an ingress port into a plurality of segments. The switching device transfers the plurality of segments to an egress port via a data path included in the switching circuits, according to a first mode of routing the packet in an absence of reading a descriptor corresponding to the packet. The switching device orders, using port logic associated with the egress port, the segments and provides sequence numbers associated with the ordered segments to port logic associated with the ingress port. The switching device validates the transfer of the plurality of segments according to the first mode based on verifying that the sequence numbers satisfy at least one criterion.

Abstract: An accelerator device and system are described, among other things. An illustrative system is disclosed to include a first sequencer programmed to append packets with information identifying a sequence number and an identification of a flow with which each packet is associated. The appended information may be used by a second sequencer to resequence the packets.

Abstract: A work descriptor identifying a plurality of workflow tasks to be performed by a hardware device is generated by a host system. A plurality of timestamp logging tasks are added to the work descriptor. Each of the plurality of timestamp logging tasks corresponds to one of the plurality of workflow tasks and instructs the hardware device to log a timestamp in response to an event associated with a respective workflow task. The work descriptor with the plurality of timestamp logging tasks is stored in a work queue of the host system. The work queue is accessible by the hardware device.

Abstract: Methods, apparatuses, and computer program products are provided for detecting an eavesdropper or other network disturbance on a quantum communication network, based on measurements performed on auxiliary degrees of freedom. An example method includes receiving a quantum state with transmitted physical observables imparted to the quantum particle/s on a first set of one or more degrees of freedom. The method further includes determining a received physical characteristic, based on the received observables within each of an auxiliary set of one or more quantum degrees of freedom. The method includes accessing data reflecting the transmitted physical condition on the auxiliary set of one or more quantum degrees of freedom and comparing the received physical characteristic of the quantum state with the transmitted physical condition. Finally, the method includes generating a notification of interference along the quantum interconnect link upon detecting a difference between the received observables and the interconnected observables.
