  • Patent number: 9672740
    Abstract: A method and system that provides detouring services to passengers and transportation operators. Transportation operators send data indicating prior uses of the operator to the passengers' mobile device and the system on the mobile device compiles the data to form travel patterns of the passenger. The travel patterns are assigned a probability indicating the frequency the travel pattern is used by the passenger. When a disruption of a service of an operator occurs, a detouring service provides detour suggestions to the passengers and travel demand changes to the operators. In another approach, an in-station display displays suggested detour routes based on the top destinations of stranded passengers and the passenger's mobile phones are not used to display or perform detouring.

  • Publication number: 20160275123
    Abstract: Some examples include a pipeline manager that creates pipeline queues across data nodes in a cluster. The pipeline manager may assign a pipeline queue connection to contiguous map-reduce jobs so that a reduce task of a first map-reduce job sends data to the pipeline queue, and a map task of a second map-reduce job receives the data from the pipeline queue. Thus, the map task of the second job may begin using the data from the reduce task of the first job prior to completion of the first job. Furthermore, in some examples, the data nodes in the cluster may monitor access success to individual pipeline queues. If the access attempts to access successes exceeds a threshold, a data node may request an additional pipeline queue connection for a task. Additionally, if a failure occurs, information maintained at a data node may be used by the pipeline manager for recovery.
