    Abstract: Provided is an apparatus directing to a speculative read mechanism for a distributed storage system. The apparatus includes a remote direct memory access (RDMA) network interface card (RNIC) (100) for a server (250), wherein the RNIC (100) includes an onboard memory (105), a trigger control (120) and a port for connection of the RNIC (100) to a client (200). The onboard memory (105) is operable to provide a buffer (110) for storage of data from a distributed storage system for a read request from the client (200). The trigger control (120) includes a programmable trigger condition. The RNIC (100) is operable to support a speculative read of data in response to a read request snoop of a write of data to the onboard memory (105), and upon detecting the trigger condition, to provide the data in the buffer to the client (200).

    Abstract: Apparatuses, methods and storage medium associated with a memcached system are disclosed herewith. In embodiments, a server apparatus may include memory; one or more processors; a network interface card to support remote memory direct access of the memory, by a client device, for a value of a key using an address that is a morph address of a physical address of a storage location of the memory having the value; and server side memcached logic operated by the one or more processors. Other embodiments may be described and/or claimed.

    Abstract: Provided is a device and a method for route planning. The route planning device (100) may include a data interface (128) coupled to a road and traffic data source (160); a user interface (170) configured to display a map and receive a route planning request from a user, the route planning request including a line of interest on the map; a processor (110) coupled to the data interface (128) and the user interface (170). The processor (110) may be configured to identify the line of interest in response to the route planning request; acquire, via the data interface (128), road and traffic information associated with the line of interest from the road and traffic data source (160); and calculate, based on the acquired road and traffic information, a navigation route that matches or corresponds to the line of interest and meets or satisfies predefined road and traffic constraints.
