20100312762 | Multi-Core Scheduling for Parallel Queries - An operator manager may be configured to determine a number of available cores and to assign the cores among a plurality of operators of a query, the operators including a running set of operators through which a plurality of query paths exist. The operator manager may include a status monitor configured to determine the number of available cores and to determine the running set of operators, a critical path selector configured to determine a critical path of the query from among the query paths and the running set of operators, and a workload manager configured to assign a first core of the available cores to a running operator of the running set and of the critical path, and to thereafter receive a new critical path from the critical path selector and to assign a second core of the available cores to the running operator of the new critical path. | 12-09-2010 |
20100318495 | CORRELATION AWARE SYNCHRONIZATION FOR NEAR REAL-TIME DECISION SUPPORT - A query handler may be configured to receive a query which is applicable against different combinations of a plurality of remote databases and a corresponding plurality of replica databases including at least some replicated data of respective ones of the remote databases, wherein the query arrives at a plurality of query arrival times and is executed at a plurality of query execution times. A replication manager may be configured to execute a synchronization plan for at least one selected replica database in which a selected synchronization timestamp of the at least one selected replica database is updated to a target synchronization timestamp, wherein the synchronization occurs during a synchronization processing time. A synchronization scheduler may be configured to schedule the synchronization plan to increase an information value of a query response, including selecting the target synchronization timestamp including relating the synchronization processing time to a selected query execution time. | 12-16-2010 |
20100318559 | Information Value-Driven Near Real-Time Decision Support - Information-based decision support may be provided by a query handler configured to receive a query which is applicable against different combinations of a plurality of remote databases and a corresponding plurality of replica databases including at least some replicated data of respective ones of the remote databases, wherein each replica database is synchronized with a corresponding remote database at a plurality of synchronization times and the different combinations include future versions of the replica databases defined by corresponding synchronization times. A query plan generator may be configured to determine information values associated with at least a subset of the different combinations, based on a query value associated with the query and on a diminishment of the query value caused by a corresponding combination, and further configured to generate, based on the information values, a query plan including at least one combination of the different combinations for executing the query therewith. | 12-16-2010 |
20100325281 | SLA-Compliant Placement of Multi-Tenant Database Applications - A placement manager may be configured to determine a placement of a plurality of tenant databases with a plurality of servers. The placement manager may include an input handler configured to determine constraints of a service level agreement (SLA) governing an association of the plurality of tenant databases with the plurality of servers and computational constraints associated with the plurality of servers, a chromosome comparator configured to compare a plurality of chromosomes, each chromosome including a potential placement of each of the plurality of tenant databases with one of the plurality of servers, and configured to compare each of the plurality of chromosomes based on compliance with the SLA constraints and relative to the computational constraints, to thereby output a selected subset of the plurality of chromosomes. The placement manager also may include a chromosome combiner configured to combine chromosomes of the selected subset to obtain a next generation of chromosomes for output to the chromosome comparator for comparison therewith of the next generation of chromosomes with respect to the SLA constraints and the computational constraints. | 12-23-2010 |
20110093852 | CALIBRATION OF RESOURCE ALLOCATION DURING PARALLEL PROCESSING - A first performance measurement of an executing task may be determined, while the task is executed by a first number of nodes operating in parallel. A second performance measurement of the executing task may be determined, while the task is being executed by a second number of nodes operating in parallel. An overhead factor characterizing a change of a parallelism overhead of executing the task with nodes executing in parallel may then be calculated, relative to a change in a number of the nodes, based on the first performance measurement and the second performance measurement. Then, an optimal number of nodes to operate in parallel to continue executing the task may be determined, based on the overhead factor. | 04-21-2011 |
20110314233 | MULTI-CORE QUERY PROCESSING USING ASYNCHRONOUS BUFFERS - A system may include a buffer monitor configured to monitor buffer content of a buffer being used during processing of a query workflow in which write tasks of the query workflow write data to the buffer and read tasks of the query workflow read data from the buffer, the buffer having a buffer capacity. The system may include a threshold manager configured to compare the buffer content to a low threshold and to a high threshold that are defined relative to the buffer capacity, and a speed controller configured to control a number of the write tasks relative to a number of the read tasks that are currently executing the query workflow, to thereby maintain the buffer content between the low threshold and the high threshold. | 12-22-2011 |
20130268307 | RESOURCE ALLOCATION MANAGEMENT - In accordance with aspects of the disclosure, a system and methods are provided for managing resource allocation by generating a finance-investment plan relative to one or more time intervals while maintaining a cash reserve at a predetermined threshold based on information related to financial activities including asset related activities and liability related activities. The systems and methods may include evaluating accounts receivable patterns for each asset to determine cash surplus ranges within the one or more time intervals, evaluating accounts payable patterns for each liability to determine cash flow gaps within the one or more time intervals, maintaining an asset-to-liability ratio during the one or more time intervals, and generating the finance-investment plan while maintaining the cash reserve at the predetermined threshold within the one or more time intervals based on the asset-to-liability ratio and potential cash flow forecasting schemes for each asset and liability. | 10-10-2013 |
20140019186 | CAPACITY PLANNING MANAGEMENT - In accordance with aspects of the disclosure, systems and methods are provided for capacity planning management by generating a capacity expansion plan for a plurality of production resources used to produce one or more products relative to one or more time intervals. The systems and methods may include evaluating production patterns for each production resource to determine a production capacity within each time interval, evaluating budget patterns for each production resource to determine a production cash flow within each time interval, generating one or more potential capacity expansion forecasting schemes for each production resource and production budget based on the production patterns for each production resource and the budget patterns for each production budget, and generating the capacity expansion plan within each time interval based on the one or more potential capacity expansion forecasting schemes for each production resource and production budget. | 01-16-2014 |
