Abstract: Backfill scheduling techniques are used to schedule execution of applications, either on a local computing unit or a remote unit. In determining whether a particular application is to be scheduled to execute on a local unit or a remote unit, the data associated with that application is considered. As examples, an amount of data to be moved, availability of communication channels, and/or availability of remote data storage resources are considered.

Abstract: A facility is presented for scheduling computer jobs of a computing environment having a plurality of computing nodes. The facility includes scheduling N sequential computer jobs of a job queue until achieving a top job party, wherein N?2, and the number of jobs in the top job party is dynamically determined by monitoring backfill window coverage of the computing nodes by the N scheduled jobs and automatically closing membership in the top job party once (i) all computing nodes are covered by at least one backfill window, or (ii) a backfill end time of at least one computing node is greater than or equal to a maximum wallclock limit of a set of job classes having the N scheduled jobs. Responsive to determining the top job party, the facility then backfill schedules jobs of the job queue around the top job party for execution.

Abstract: A method is provided for starting a job in a parallel batch job data processing system in which a job is submitted to a scheduler having available, for use, a plurality of resource classes in the data processing system and by also including, within the job, instructions which cause notification of job starting to the scheduler and then, upon this notification, removing the job from all but the first resource class on which it is started.

Abstract: The security of data is enhanced by the use of cyclic redundancy checks. Data is encoded with one or more cyclic redundancy checks and then transmitted by a transmitter to a receiver. The receiver receives the encoded data and decodes it in order to use the one or more cyclic redundancy checks to determine whether the data was sent by an authorized user.

Abstract: Balancing the workload of a grid computing environment. A manager daemon obtains information from a plurality of schedulers of a plurality of systems of the grid computing environment and uses that information to balance the workload of the environment. The information includes an indication of free resources, idle jobs, and possibly other information.
