Abstract: External job scheduling capabilities are provided to a local job control system lacking or having insufficient job scheduling capabilities. This is accomplished by encapsulating running of a user job by the local job control system (LJCS) within running of a marker job at a node management system, which is responsive to an external resource scheduler. The technique includes starting a marker job by the resource scheduler external to the local job control system, wherein the marker job corresponds to a user job to be run by the LJCS; responsive to starting of the marker job, starting the user job by the LJCS; and upon termination of the user job, ending the marker job started by the resource scheduler, wherein starting of the user job by the LJCS is responsive to the resource scheduler's starting of the marker job and wherein ending of the marker job is responsive to termination of the user job.

Abstract: A job scheduler module for a distributed processing system is provided with capability to protect jobs from planned or unplanned subsystem downtimes. The approach includes determining a downtime for a subsystem of the distributed processing system, determining at least one of a start time and an end time of a job to be executed using the subsystem, determining whether the start time or the end time of the job is within the downtime, and if not, placing the job in an eligible job list. The scheduler then makes a decision whether to start the job using the eligible job list. A downtime protection flag can be associated with each job, thereby allowing a user to indicate whether the job is to receive subsystem downtime protection. If not, then the job is placed directly in the eligible job list for scheduler execution irrespective of subsystem downtime.

Abstract: A system searches a data vector as a genome for a template vector such as a DNA fragment. The system Exclusive ORs the template vector with a like size segment of the data vector, element by element, and sums the results of the Exclusive OR operations, whereby a zero sum indicates a match and a nonzero sum indicates a lack of match. Then, the system shifts the segment one element and repeats the Exclusive ORing and Summing steps for the shifted segment. Each of the elements is represented by a respective digital value, and the values are assigned such that the result of the Exclusive ORing for each combination of elements yields a value representing the degree of mismatch between the elements in the combination.

Abstract: In an event-driven, virtual time logic simulation system, user-initiated requests for setting and holding simulated logic circuit elements are accommodated during forward simulation, rollback, and advance of system global virtual time.
