Abstract: Disclosed aspects include managing a set of wear-leveling data with respect to a set of physical cores of a set of compute nodes. A set of physical cores of the set of compute nodes may be monitored using a set of processor utilization resource registers (PURRs) to identify the set of wear-leveling data. By monitoring the set of physical cores of the set of compute nodes, a set of thread events with respect to the set of physical cores of the set of compute nodes may be detected. Based on the set of thread events, the set of wear-leveling data may be determined. The set of wear-leveling data may then be established in a data store. The wear leveling data may be used to manage asset placement with respect to a shared pool of configurable computing resources.

Abstract: Techniques are disclosed for monitoring the performance of transient virtual volumes created for a virtual machine. Each transient virtual volume is created in response to a first trigger event, used by the virtualization environment solely to perform a single function supporting execution of the virtual machine, and deleted in response to a second trigger event. When creation of a current transient virtual volume is detected, and while the virtualization environment uses the current transient virtual volume to perform a single function supporting execution of the virtual machine, performance data is collected for the current transient virtual volume, and combined with performance data collected for at least one other, previously deleted transient virtual volume that was used solely to perform the same single function supporting execution of the same virtual machine. The combined performance data is represented as performance data for a single monitored virtual volume associated with the virtual machine.

Abstract: A method, a computer program product, and a computer system for processing interrupt requests in a computer system. The computer system disables, for a processor, an interrupt request for threads other than an interrupt request handling thread. The computer system configures the processor to route the interrupt request to the interrupt request handling thread. The computer system determines, by the interrupt request handling thread, whether one of the threads needs to process the interrupt request. The computer presents, by the interrupt request handling thread, the interrupt request to the one of the threads, in response to determining that the one of the threads needs to process the interrupt request.

Abstract: A system and method for cooperative notification offloading supports thread notification offloading in a multi-threaded messaging system such as a distributed data grid. Pending notifiers are maintained in a collection of pending notifiers. A signaling thread processes a first notifier in the collection of pending notifiers to wake a first thread. The first awoken thread processes additional notifiers in the collection of pending notifiers to wake additional threads. The additional awoken threads can process additional notifiers in a cycle until all pending notifiers in the collection are processed. Such cooperative notification offloading of notifier processing from the signaling thread improves performance of the signaling thread with respect to other tasks thereby improving performance of the signaling thread and the distributed data grid.

Abstract: Disclosed aspects include managing asset placement with respect to a shared pool of configurable computing resources. A set of wear-leveling data may be detected for a set of hosts of the shared pool of computing resources. Based on the wear-leveling data, a placement arrangement for the set of assets may be determined with respect to the set of hosts of the shared pool of configurable computing resources. The placement arrangement may be based on a lesser utilized hardware factor which indicates a lesser likelihood of a hardware error event. Based on the placement arrangement, the set of assets may be placed with respect to the set of hosts of the shared pool of configurable computing resources.

Abstract: Computer systems attempt to manage resource pools of a dynamic number of similar resources and work tasks in order to optimize system performance. Work requests are received into the resource pool having a dynamic number of resources instances. An instance-throughput curve is determined that relates a number of resource instances in the resource pool to throughput of the work requests. A slope of a point on the instance-throughput curve is estimated with stochastic gradient approximation. The number of resource instances for the resource pool is selected when the estimated slope of the instance-throughput curve is zero.

Abstract: A method, system and computer-usable medium are disclosed for dynamic load based resource sets that provide flexible assignment of resources to processes with nested resource sets. Resource sets include plural resource subsets so that processes that are assigned to a resource subset can have additional resources flexibly made available by providing additional resources from a parent resource set. A resource threshold is monitored to selectively adjust process resource subset assignments based upon utilization of resources within a resource subset, such as by comparing the number of threads assigned to a resource subset with the number processors available to run the threads.

Abstract: Example methods and systems are directed to dispatching database tasks. An application may access data associated with a task. The data may indicate features (e.g., processing functionality) that will be used to complete the task. The application may determine whether all such features are implemented in the database layer. The application may dispatch the task to the database layer if all features are implemented therein. The application may perform the task in the application layer if one or more of the features are not available in the database layer. In some example embodiments, the task involves materials requirements planning. Such a task may include determining, for a given bill of materials (“BOM”), the quantity of materials available on-hand, the quantity available from suppliers, the transport or delivery time for the various quantities, and other data regarding the BOM.

Abstract: A virtual assembly builder for use in virtualization environments, which can be used as a tool for virtualizing installed components in a reference environment, modifying those components if necessary, and then deploying them into another/target environment. Using the virtual assembly builder, a user (e.g., an administrator) can capture the configuration and product/component binaries of existing software components into software appliance artifacts. Appliances can be grouped, and their relationships defined, into software assembly artifacts. Logical connections between appliances within an assembly can be reconfigured by a process of assembly editing. When a desired assembly configuration has been achieved, the assembly can be prepared for, and deployed into, the target environment.

Abstract: A workflow is designated for execution across a plurality of autonomous computational entities automatically. Among other things, the cost of computation is balanced with the cost of communication among computational entities to reduce total execution time of a workflow. In other words, a balance is struck between grouping tasks for execution on a single computational entity and segmenting tasks for execution across multiple computational entities.

Abstract: A system and method for dynamically determining parameters of crafting activities for individual users in a virtual space are disclosed. The crafting activity parameters may be determined based on rate of usage of the virtual space by the users. In some examples, a user usage rate of the virtual space may be determined to measure an amount of time a user spend in the virtual space during a period of real-world time. Based on the determined user usage rate of the virtual space, crafting activity parameters may be determined, for example, to balance differences in time spent in the virtual space by the users. In some implementations, for such determinations of the crafting activity parameters, one or more user normalization standards may be obtained.
