  • Patent number: 10705935
    Abstract: A method and system for generating a job alert. According to embodiments of the present invention, before a target job is processed, a characteristic of input and output of the target job in at least one stage is determined through analyzing a historical job, and a resource overhead associated with the processing of the target job is calculated based on the characteristic of input and output. Then, an alert for the target job is generated in response to the resource overhead exceeding a predetermined threshold. In such manner, an alert for the target job can be proactively generated before the resource overhead problem occurs, so as to enable an administrator or developer to discover a fault in advance and adopt measures actively to avoid loss and damage to the intermediate results or output data when the target job is processed.

  • Patent number: 10678984
    Abstract: The available delivery capability (ADC) of a power distribution network with respect to a power transaction is evaluated in real-time. The power transaction involves simultaneous power deliveries from power sources in a source area to loads in a sink area. First, a list of contingencies are ranked in the power distribution network with respect to static security constraints to obtain a subset of top-ranked contingencies. For each top-ranked contingency in the subset, a representation of the power transaction in a steady state of the power distribution network, in a form of parameterized three-phase power flow equations, is solved to obtain a corresponding power delivery capability (PDC) and a corresponding binding constraint among the static security constraints. The reliability of the power transaction in the power distribution network is then evaluated based on, at least in part, a first contingency PDC which is a smallest PDC among obtained corresponding PDCs.
