20120140355 | Reliability-Aware Disk Power Management - A token value is maintained based on an allowable number of low power transitions of a hard disk drive without adversely affecting reliability, compared to an actual number of low power transitions of said hard disk drive. The allowable number of low power transitions increases over the hard disk drive's lifetime. Before the hard disk drive performs a low power transition, the token is evaluated to determine if the hard disk drive is allowed to perform a low power transition. Low power transitions discussed include parking the head and spinning-down the hard disk drive. | 06-07-2012 |
20120210149 | TECHNIQUES FOR PERFORMING STORAGE POWER MANAGEMENT - A technique for performing storage power management on storage subsystems includes measuring, using a power measurement device, power consumption of a storage subsystem. A first average power and a second average power for the storage subsystem are calculated based on the measured power consumption. In this case, the first average power is calculated over a shorter time period than the second average power. One or more first actuators are incremented in response to the first average power of the storage subsystem being greater than a first power level to reduce the first average power of the storage subsystem below the first power level within a first time period. One or more second actuators are incremented in response to the second average power of the storage subsystem being greater than a second power level and less than the first power level to reduce the second average power of the storage subsystem below the second power level within a second time period that is greater than the first time period. Finally, one or more of the first actuators and the second actuators are decremented in response to the second average power of the storage subsystem being more than an offset below the second power level to increase the power consumption of the storage subsystem. | 08-16-2012 |

20130282788 | File System Optimization by Log/Metadata Analysis - A mechanism is provided in a data processing system for optimization of a distributed file system by log data analysis. A name node in the distributed file system initiates a log analysis map/reduce job on one or more connected data nodes via a map/reduce processing framework in the distributed file system and receives result data resulting from the log analysis map/reduce job from the one or more connected data nodes via the map/reduce processing framework in the distributed file system. The name node performs analysis on the received result data and generates an optimization plan for the one or more connected data nodes based on results of the analysis. The name node initiates the optimization plan on the one or more connected data nodes via the map/reduce processing framework in the distributed file system. | 10-24-2013 |
20140337357 | DOCUMENT TAGGING AND RETRIEVAL USING PER-SUBJECT DICTIONARIES INCLUDING SUBJECT-DETERMINING-POWER SCORES FOR ENTRIES - Techniques for managing big data include tagging of documents and subsequent retrieval using per-subject dictionaries having entries with subject-determining-power scores. The subject-determining-power scores provide an indication of the descriptive power of the term with respect to the subject of the dictionary containing the term. The same term may have entries in multiple dictionaries with different subject-determining-power scores in each of the dictionaries. A retrieval request for one or more documents containing search terms descriptive of the one or more documents can be processed identifying a set of candidate documents tagged with subjects and optional terms, and then applying subject-determining-power scores from the multiple dictionaries for the search term to determine a subject for the search term. The method then selects the one or more documents from the candidate documents according to the subject. | 11-13-2014 |

20090031316 | Scheduling in a High-Performance Computing (HPC) System - In one embodiment, a method for scheduling in a high-performance computing (HPC) system includes receiving a call from a management engine that manages a cluster of nodes in the HPC system. The call specifies a request including a job for scheduling. The method further includes determining whether the request is spatial, compact, or nonspatial and noncompact. The method further includes, if the request is spatial, generating one or more spatial combinations of nodes in the cluster and selecting one of the spatial combinations that is schedulable. The method further includes, if the request is compact, generating one or more compact combinations of nodes in the cluster and selecting one of the compact combinations that is schedulable. The method further includes, if the request is nonspatial and noncompact, identifying one or more schedulable nodes and generating a nonspatial and noncompact combination of nodes in the cluster. | 01-29-2009 |
