Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Abstract: Apparatus and methods are disclosed for solving Mixed Integer Programming (MIP) problems, such as Security Constrained Unit Commitment (SCUC) problems used by power grid authorities to perform day-ahead market clearing. In certain examples, a plurality of threads of a software tool implementing a concurrent optimizer can be executed concurrently and sequentially to generate new solutions to a SCUC problem for an upcoming planning horizon. Data can be shared among the concurrently executing threads, such as intermediate/incumbent solutions and hints regarding the fixing of variables and constraints to reduce the size of the SCUC problem. In some examples, the threads are seeded with historical solutions from prior planning horizons. The software tool can select a best solution from the solutions generated by the threads, and determine dispatch instructions for a device coupled to the power grid for the upcoming planning horizon based at least in part on the selected solution.

Abstract: Fast simultaneous feasibility testing (SFT) for management of an electrical power grid is achieved through various innovations. The computation problem relates to evaluation of candidate solutions for external power flows into a power grid, with respect to predetermined constraints and contingencies. A perturbation approach with precomputation is extended to encompass grid states (e.g. time periods) in addition to contingencies. Advantages derive from: fewer factorizations or inversions of large matrices; decoupling of state-dependent and contingency-dependent perturbations, leaving relatively few perturbations jointly dependent on both state and contingency; or making approximations by discarding small jointly dependent terms. Significant computation reductions allow a single workstation to perform SFT for 36 hours of a day-ahead cycle.

Abstract: Adaptive digital content preprocessing techniques based on a bitrate are described. In an implementation, a parameter of a preprocessing module is set based on a target bitrate. The parameter specifies an amount of preprocessing to be performed in preprocessing digital content. Preprocessed digital content is generated by preprocessing the digital content by the specified amount using the preprocessing module. Encoded digital content is generated by compressing the preprocessed digital content using a compression technique by an encoder. The encoded digital content is then transmitted for communication at the target bitrate.
