Abstract: A coupling facility is coupled to one or more other coupling facilities via one or more peer links. The coupling of the facilities enables various functions to be supported, including the duplexing of structures of the coupling facilities. Duplexing is performed on a structure basis, and thus, a coupling facility may include duplexed structures, as well as non-duplexed or simplexed structures.

Abstract: Techniques are provided for storing files in a parallel computing system based on a user-specification. A plurality of files generated by a distributed application in a parallel computing system are stored by obtaining a specification from the distributed application indicating how the plurality of files should be stored; and storing one or more of the plurality of files in one or more storage nodes of a multi-tier storage system based on the specification. The plurality of files comprise a plurality of complete files and/or a plurality of sub-files. The specification can optionally be processed by a daemon executing on one or more nodes in a multi-tier storage system. The specification indicates how the plurality of files should be stored, for example, identifying one or more storage nodes where the plurality of files should be stored.

Abstract: A computer program product, system, and computer implemented method comprising intercepting, by an interceptor, IO send on an IO path to a storage array; sending a copy of the IO and metadata to a message bus, and enabling a consumer to register with the message bus to consume events sent to the message bus.

Abstract: An application is included in a virtual machine sent to a cloud computing server. The cloud computing server has a remote access layer that fetches data blocks of the private dataset of the application from private data storage as the data blocks are requested by the application, so that the application in the public cloud begins execution without waiting for the entire application dataset to be transferred to the public cloud, and the data blocks are transferred from the private dataset to the public cloud only when the data blocks are accessed by the application. The application's private data is kept in the public cloud only when it is currently being used. If there are security concerns, the application's private data is transferred over the public network in an encrypted form and stored in the public cloud in an encrypted form.

Abstract: The configuration of the logical processors of a logical partition is managed dynamically. A logical partition is initially configured with one or more logical processors. Thereafter, the configuration can be dynamically adjusted. This dynamic adjustment may be in response to workload of the logical partition.

Abstract: A configuration management database system includes a plurality of configuration items. Each of the configuration items includes at least one property relating to a component of an IT system. The system also includes a plurality of intensional category definitions that provide dynamic categorization of the plurality of information items. Each of the intensional category definitions includes a predicate that is operable to identify an input one of the configuration items as a member of the category based on the at least one property in the input one of the configuration items. The configuration management database system also includes at least one pre-computed category membership data structure to support efficient processing of at least one query.

Abstract: Heuristics are employed to dynamically determine whether a given request is to be driven synchronously or asynchronously. The average synchronous service time associated with previously processed requests is monitored and used, in real-time, along with other information, to determine whether the given request is to be driven synchronously or asynchronously.

Abstract: A method and apparatus for enforcing capacity limitations such as those imposed by software license agreements in an information handling system in which a physical machine is divided into a plurality of logical partitions, each of which is allocated a defined portion of processor resources by a logical partition manager. A software license manager specifies a maximum allowed consumption of processor resources by a program executing in one of the logical partitions. A workload manager also executing in the partition measures the actual consumption of processor resources by the logical partition over a specified averaging interval and compares it with the maximum allowed consumption. If the actual consumption exceeds the maximum allowed consumption, the workload manager calculates a capping pattern and interacts with the logical partition manager to cap the actual consumption of processor resources by the partition in accordance with the calculated capping pattern.
