摘要： Computer-implemented methods for estimating the energy consumption of a workload in a Cloud computing system are provided. Aspects include receiving a request for an estimated energy consumption of the workload and obtaining characteristics of the Cloud computing system executing the workload. Aspects also include identifying and employing a unified power consumption model from a power model database based on the characteristics and calculating the estimated energy consumption of the workload based on the unified power consumption model.

摘要： Systems, computer-implemented methods, and computer program products that can facilitate performance biased resource scheduling based on runtime performance of a certain workload type on one or more nodes are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a performance component that assigns performance points to different nodes based on execution of one or more workload types. The computer executable components can further comprise a scheduler extender component that modifies a scheduling decision to run a workload type on a node based on the performance points.

摘要： Technology for selecting job characteristics to determine the similarity among jobs in terms of performance. Technology based on similarity among jobs calculated by selected characteristics for determining jobs that are likely to lead to successful performance of a requested new job by a cloud. Also, technology based on similarity among jobs calculated by selected characteristics for determining jobs that are likely to lead to failure when performing a requested new job by the cloud. When the new job request is accepted, because its characteristics of the new job matches job characteristics characterized by success and/or fails to match job characteristics characterized by failure, then the new job is said to lead to a “reward” or an “expected reward” because the new job will be rewarded by being allowed to use, by an admission controller of a cloud management system, use of cloud computing resources of the cloud.

摘要： Method and apparatus for configuring relevant parameters of MapReduce applications. The method includes: receiving a request for processing a first MapReduce job; obtaining job feature attributes of historical MapReduce jobs; searching out a job feature attribute of a second MapReduce job associated with the first MapReduce job from within the job feature attributes of the historical MapReduce jobs; configuring relevant parameters of the first MapReduce job based on the job feature attribute of the second MapReduce job. According to this method of configuring parameters, network overheads of file transfer can be effectively reduced, the method of configuring parameters of the MapReduce job can be processed locally as much as possible, thereby effectively increasing system resource utilization while reducing the administrator's configuration burden. An apparatus for configuring relevant parameters of MapReduce application is also provided.

摘要： A mechanism is provided for identifying a usage for data in a data structure. A set of configuration files associated with a set of services are analyzed to identify at least one class associate with the data in the data structure thereby forming a data structure-to-class mapping. Source code associated with the set of services is analyzed to identify a set of services used by at least one class in the data structure-to-class mapping thereby forming a service-to-class mapping. A set of specification files associated with the set of services are analyzed to identify a set of uses associated with at least one service in the service-to-class mapping thereby forming a use-to-service mapping. An identification of usage information of the data structure is generated using the data structure-to-class mapping, the service-to-class mapping, and the use-to-service mapping.

摘要： Processing time sequence data for multiple sensors, wherein the multiple sensors are divided into multiple sensor groups and each data comprises a time stamp and a value associated with the timestamp. The method comprises: receiving time series data from each sensor; assigning the time series data received to a sensor group to which the sensor belongs; storing time series data in a first database of a first memory, such that multiple time series data assigned to the same sensor group in the multiple sensor groups are stored in at least one database record of the first database; obtaining the time series data of each sensor among the multiple sensors from the first database; storing time series data in a second database of a second memory, such that the multiple time series data from the same sensor are stored in at least one database record of the second database.

摘要： Generation of a schema of a NoSQL type database, where a set of entry(ies) of a NoSQL type database can be determined, and the record schema is a treelike relationship between key hierarchies with a key as a node in the entry, wherein the key corresponds to an attribute name. For at least one record schema, a node in which there is an attribute name variation is determined based on a similarity of sub-nodes in the treelike relationship, and the record schema is updated according to the determined result. The schema of the NoSQL type database is generated based on the updated record schema.
