摘要： Embodiments of the invention provide a method of optimizing a query, including determining an execution plan for use in executing the query, based on a monetary cost of the energy needed to execute the query. A query optimization component may determine a plurality of execution plans for the query. The query optimization component may then select one of the plans to use in executing the query based on the monetary cost calculated for the plan.

摘要： Embodiments of the invention provide an interrupt handler configured to distinguish between critical and non-critical unrecoverable memory errors, yielding different actions for each. Doing so may allow a system to recover from certain memory errors without having to terminate a running process. In addition, when an operating system critical task experiences an unrecoverable error, such a task may be acting on behalf of a non-critical process (e.g., when swapping out a virtual memory page). When this occurs, an interrupt handler may respond to a memory error with the same response that would result had the process itself performed the memory operation. Further, firmware may be configured to perform diagnostics to identify potential memory errors and alert the operating system before a memory region state change occurs, such that the memory error would become critical.

摘要： A minimally degraded configuration is determined when failing connections occur. Associative deconfigurations are determined from deconfiguring hardware items in a server system, associative groups are derived, and failed connections are determined. Failed connections are determined between two hardware items that are in the same associative group, and the two hardware items at both endpoints of the failed connection are deconfigured. Each associative group state is set to unknown, and the failed connections are counted where a single endpoint of the failed connection is within the associative group. The associative group state is set to deconfigured, if a member of the associative group was deconfigured. Counts of the associative groups that remain in the unknown state are analyzed, and the associative group with the smallest failed connection count is selected and set to a configured state. The other associative group at the other end is set to a deconfigured stated, and the hardware item in the other associative group is deconfigured.

摘要： Method, apparatus and system are described for converting received timestamps to a time-recording standard recognized by the receiving computing system. Embodiments of the invention generally include receiving data from an external device that includes a timestamp. If the received data is the first communication from the external device, creating a time base used for converting subsequently received timestamps to a recognized standard. Moreover, the system updates the time base if a counter failure at the external device is detected. When the external device transmits subsequent data, the time base is added to the subsequently received timestamps to convert the subsequent timestamps to a time-recording standard recognized by the computing system.
