Abstract: Generally discussed herein are systems, devices, and methods for data distribution in a distributed data processing system (DDPS). A device of a distributed data processing system may include a storage device to store data regarding data nodes (DNs), switches, and racks on which the DNs and at least some of the switches reside, and circuitry to receive, from a name node or a client node of the DDPS and coupled to the device, a first communication indicating one or more DNs to which a portion of a file is to be replicated, determine a component in a data path between the client node and one or more of the DNs at which to mirror the portion of the file, and provide a second communication indicating the component at which the data is to be mirrored, one or more of the DNs to receive the portion of the tile, and the corresponding one or more of the racks on which the DNs reside.

Abstract: Examples include techniques for a field programmable gate array (FPGA) to perform one or more functions for an application specific integrated circuit (ASIC). Example techniques include communication between the ASIC and the FPGA via a sideband communication link to enable the ASIC to indicate to the FPGA a need for the FPGA to perform a function to fulfill a request received by the ASIC.

Abstract: A software defined network (SDN) ecosystem can include simulating operation of new SDN applications and providing access to SDN applications to users of the SDN ecosystem.
