A storing unit stores a data set including a plurality of data elements and a first Bloom filter used to determine whether a query-target data element is present in the data set. A calculating unit deletes, when some data elements are deleted, a first bit array from the first Bloom filter. The first bit array has the number of bits corresponding to the number of deleted data elements. When a query-target first data element is entered, the calculating unit adds a second bit array temporarily to a second Bloom filter obtained by deleting the first bit array. The second bit array has the same number of bits as the first bit array, with all bits set to a specific value. Using the second Bloom filter, the calculating unit determines whether the first data element is present in the data set, from which some data elements have been deleted.

Data presence/absence determination apparatus and computer-readable storage medium storing program for determination of data presence/absence

An information processing system includes a plurality of information processing apparatuses, a management apparatus including a first processor, and configured to manage execution of jobs by the plurality of information processing apparatuses; and a terminal apparatus including a second processor. The first processor is configured to identify an information processing apparatus not executing a job among the plurality of information processing apparatuses, transmit information on the number of identified information processing apparatuses, and upon receiving identification information on at least one job to be executed on the information processing apparatus not executing a job from the terminal apparatus, perform scheduling so that the information processing apparatus not executing a job executes the job.
