Abstract: A system for dynamically parallelizing the loading operation for loading a data file onto a database. The dynamic parallelization of the loading operation involves scanning the data file in segments, such that scanning of an individual segment terminates when the scanned information is enough to enable loading of the segment across a plurality of exclusive-access memory blocks. Following the scanning of the first data file segment, the parallelized loading of each scanned segment occurs in a lock-step-mode with the scanning operation. As such, the loading of each scanned data segment is performed in parallel across multiple exclusive-access memory location, as determined by the prior scanning results, and furthermore in parallel with the scanning of a subsequent segment of the data file.

Abstract: A system for generating a parallel calculation plan to evaluate a rule-set or a rule-based expression list by spilling the list of rule-based expressions into multiple task units and reconfiguring all independent task units at the same calculation levels into several parallelized task groups such that task units within each task group may be scheduled for parallel execution across a cluster of processing nodes. The parallelization may be dynamically determined based on generated tasks but may further be subject to an additional layer of parallelization based on range-based splitting of each task into multiple parallel executable subtasks. The final parallelized calculation plan may include a set of sequentially ordered task groups based on logical dependencies and problem partitioning with information regarding parallelized execution of each task group.

In one embodiment, the method includes receiving data packets into a system port buffer having different queues. Also, counters are associated with the queues. Further, the method includes scanning the counters, in which the counters count the number of dropped data packets associated with an individual queue of the different queues. Moreover, the method includes determining if the number of dropped data packets for an individual queue is greater than a predetermined number. If the number of dropped data packets is greater than the predetermined number, then a message is generated.
