Abstract: A system, method, and a computer-readable storage device for sloppy feedback loop compilation are described herein. For example, a dataflow application definition can be obtained. The dataflow application definition may include a feedback loop bounding a compute block. It may then be determined that the feedback loop is to be compiled as a sloppy feedback loop. The dataflow application can then be compiled as an executable object that pipelines the compute block of the dataflow application.

Abstract: A signal transmitted from a mobile device is received at an antenna array of a device. Motion information of the mobile device is received from a sensor of the mobile device. A change in the AoA of the signal is computed when the mobile device moves from a first position to a second position. The location of the mobile device relative to the antenna array is determined based on the change in AoA of the signal and the motion information of the mobile device.

Abstract: In example implementations, an apparatus includes a bus waveguide, a plurality of optical gates coupled to the bus waveguide and an injection coupler. The bus waveguide receives a plurality of constraint signals. Each optical gate outputs an internal state via a local phase shift when at least one of the plurality of constraint signals has a wavelength that matches a respective resonant wavelength. The injection coupler combines the at least one of the plurality of constraint signals with additional constraint signals that are injected. An error is detected in a bit of a message when an overall phase shift has occurred to the at least one of the plurality of constraint signals causing a power level to exceed a power level threshold of an optical gate when the at least one of the plurality of constraint signals constructively interferes with the additional constraint signals that are injected.

An example method includes determining a back-end bandwidth of a storage system, wherein the back-end of the storage system includes a storage drive communicatively coupled to a storage controller. The method also includes determining a front-end bandwidth of the storage system, wherein the front-end of the storage system includes a front-end bus coupling the storage controller to a host. The method also includes computing a target back-end memory bandwidth based on the back-end bandwidth and computing a target front-end memory bandwidth based on the front-end bandwidth. The method also includes reducing power consumption of the storage controller by reducing a clock frequency of a memory device of the storage controller based on the greater of the target back-end memory bandwidth and the target front-end memory bandwidth.

Abstract: Method and apparatus for replicating data structures over a network in which each data structure is assigned an owner node among a plurality of networked peer nodes. Preferably that owner can be ascertained through information in the data structure. When an update to the data structure is desired by a non-owner, a request to modify the data structure is sent out on the network and when received by the owner, the owner performs the modification. The owner node can then notify the other nodes regarding the update. The method, implemented through a single-writer, multiple-reader paradigm, insures availability, partition tolerance and eventual consistency; it avoids the high overhead costs and single point of failure drawbacks of the prior art centralized management and locking protocols. Administrators can connect to any peer node in the network to manage, monitor and request modifications to a data structure.

Abstract: Example implementations relate to access point group transmissions. For example, an access point can include instructions to determine a first mesh point to be a first hop for a first data packet and determine a second mesh point to be a second hop for a second data packet. In some examples, the access point can include instructions to group the first mesh point and the second mesh point, and utilize the group to simultaneously transmit the first data packet to the first mesh point and the second data packet to the second mesh point.

The pipeline table may be able to implement the match field and the action.

Abstract: Example implementations relate to a storage memory direct access (SMDA) provider. The SMDA provider may pin a storage memory region to a memory address of a consumer machine, the storage memory region corresponding to a storage range of a storage device requested by the consumer machine. The SMDA provider may atomically commit data in the storage memory region accessed by the consumer machine via the memory address.

Abstract: A network switch for implementing a Software Defined Network can include one or more memory resources storing a flow table and including a buffer. The network switch can receive and analyze data packets to generate a lookup key for each respective data packet. Using the lookup key, the network switch can perform a lookup in the flow table to determine a rule number for the respective data packet. Based on the rule number, the network switch can generate an event record for the respective data packet, and store the event record in a block of the buffer. When the block is full, the network switch can stream a set of event records from the buffer to a processing resource to enable the processing resource to update counter tables, external to the network switch, to implement the Software Defined Network.

Abstract: Methods and systems are described for assigning the proper Internet protocol (IP) address to a client device following authentication of the client device on a network. In particular, at commencement of an authentication procedure of the client device, a role is associated with the client device that denies all DHCP renews/requests. By assigning a role to the client device 103 with a “deny DHCP renew/request” rule at the commencement of an authentication procedure, the systems and methods described herein ensure that a race condition does not allow the client device to renew an IP address in an old segment of the network. Accordingly, the client device may avoid a possibly improper IP address in a segment of the network system in which the client device is no longer associated with or operating on.
