Abstract: Disclosed is an apparatus, method, and program product for observing the nodal workload balance of the system on an ongoing basis, and for dynamically changing the preferred nodes of existing threads in order to improve nodal balance. Workload balance is ascertained on a nodal basis and then thread-based workload information is collected. If the detected imbalance persists, the thread-based information is used to change the assignment of preferred nodes to threads to improve nodal workload balance.

Abstract: A packet control mechanism for a computer data system that dynamically adjusts packet training depending on the utilization load on the processor. The dynamic adjustment of packet training can be to enable and disable packet training, or adjust the number of packets in the packet train. In preferred embodiments, the computer data system includes a processor utilization mechanism that indicates a load on a processor. When the packet control mechanism determines the load on the processor is above a threshold limit, the packet control mechanism reduces the processor load by compressing the packets into the packet train. The compressing of the packets is stopped or reduced when the processor load is below a threshold in order to increase the data throughput on the network interface.

Abstract: Multiple database queries are satisfied with the same data in a manner that assures the data is current and without having to interrogate the database for each query. In a first embodiment, all queries that are received during the processing of a first query are evaluated to determine whether the result set returned for the first query will satisfy the queries received during processing of the first query. If so, the result set returned for the first query is used to generate result sets for the subsequent compatible queries received during the processing of the first query. In a second embodiment, queries are delayed and grouped, and a new query is then processed for each group that returns a result set that satisfies all of the queries in the group. In both cases, the result set for one query is used to generate a result set for a different query.

Abstract: A method, apparatus and computer program product are provided for implementing breakpoint based performance measurement. A set of hardware counters is defined for counting user specified hardware events. The hardware counters are programmable for counting predefined processor events and the predefined processor events include processor cycles. A start breakpoint instruction and a stop breakpoint instruction are inserted in hardware instructions. The hardware instructions are executed and processing of the hardware instructions is suspended responsive to executing the start breakpoint instruction. Responsive to executing the start breakpoint instruction, interrupt handler instructions are entered and breakpoint instructions are called. The breakpoint instructions generating a return from interrupt instruction to start the defined set of hardware counters and to return processing from the interrupt handler instructions to the hardware instructions. Then executing the hardware instructions is suspended responsive to executing the end breakpoint instruction to stop the defined set of hardware counters.
