摘要： An exemplary data transfer manager includes a datacenter configured to communicate over at least one link and a scheduler that is configured to schedule a plurality of jobs for communicating data from the datacenter. The scheduler determines a minimum bandwidth requirement of each job and determines a maximum bandwidth limit of each job. The scheduler determines a flex parameter of each job. The flex parameter indicates how much a data transfer rate can vary between adjacent data transfer periods for the job.

摘要： A constrained ski-rental problem is defined. In the constrained ski-rental problem, a determination as to whether a first action having a first cost associated therewith or a second action having a second cost associated therewith is more cost effective is performed based on moment information associated with events related to the first action or the second action. The moment information may include a moment of the occurrences distribution of events related to the first and second actions. The moment information may include a moment of a number of occurrences of events related to the first and second actions, a moment of the inter-event times of occurrences of events related to the first and second actions, or the like. The moment information may include a first moment, a second moment, or the like.

摘要： A data block storage management capability is presented. A file system includes a plurality of data blocks which are managed using a first storage service and a second storage service, where the first storage service has a lower storage cost and a higher input-output cost than the second storage service. The data blocks stored using the second storage service have associated therewith respective expected storage durations indicative of respective lengths of time for which the data blocks are to be stored using the second storage service (which may be the same or different across the ones of the data blocks stored using the second storage service). The expected storage durations of the data blocks are modified based on a comparison of an expected hit rate of the second storage service and a current hit rate of the second storage service or current hit rates of the data blocks.
