[Problem] Available resources are efficiently used even in a case in which continuous available resources cannot be secured on a cloud. [Solution] A resource reservation management apparatus 10 includes: a storage unit that stores a resource capacity and resource reservation information of a computing machine; a reservation notification unit 11 that receives, from a user terminal, reservation request information including an operating requested time period, an operating time, and a requested specification as a reservation of a master lease; a scheduling unit 12 that creates slave leases by splitting the operating time of the master lease in accordance with times corresponding to available resources indicated in the resource reservation information and sets the slave leases in the resource reservation information; a reservation management unit that detects occurrence of predetermined events including stop, shift, restart, and deletion of the created instances by referring to the resource reservation information; and an instance management unit 15 that transmits instruction information in accordance with an instance creation instruction and the detected predetermined events to the computing machine 15.

Methods and systems for detecting and responding to erroneous application configurations are presented. In one embodiment, a method is provided that includes receiving a configuration for an application and receiving execution metrics for the application. The configuration and the execution metrics may be compared to a knowledge base of reference configurations and reference execution metrics and a particular reference configuration may be identified from the knowledge base that corresponds to the configuration. The particular reference configuration may represent an erroneous configuration of the application that needs to be corrected. A configuration correction may then be identified based on the particular reference configuration.

A multicore processing environment (MCPE) is disclosed. In embodiments, the MCPE includes multiple processing cores hosting multiple user applications configured for simultaneous execution. The cores and user applications share system resources including main memory and input/output (I/O) domains, each I/O domain including multiple I/O devices capable of requesting inbound access to main memory through an I/O memory management unit (IOMMU). For example, the IOMMU cache associates unique cache tags to each I/O device based on device identifiers or settings determined by the system registers, caching the configuration data for each I/O device under the appropriate cache tag. When each I/O device requests main memory access, the IOMMU cache refers to the appropriate configuration data under the corresponding unique cache tag. This prevents contention in the IOMMU cache caused by one device evicting the cache entry of another, minimizing interference channels by reducing the need for main memory access.

A system for managing storage space for a computer may include at least one processor programmed to determine a maximum data space for a computing task. The at least one processor may also be programmed to create a file having a maximum size equal to or greater than the maximum data space. The at least one processor may further be programmed to create a virtual device linked to the file and mount a filesystem inside the virtual device. The at least one processor may also be programmed to mount the virtual device. The at least one processor may further be programmed to determine that the computing task is completed. The at least one processor may further be programmed to unmount the virtual device.

The present disclosure provides an access processing method, a device, a storage medium and a program product. A specific implementation solution is: by creating a plurality of container components on a service platform, the container components can realize a life cycle management of functional modules. A resource control center determines functional modules required by a business system and the deployment number of each of the functional modules according to an access requirement of the business system; allocating container components corresponding to the deployment number of each of the functional modules according to the deployment number of each of the functional modules; binding each of the functional modules with the corresponding container components; and in response to a binding of a container component and a functional module, loading and running the functional module by the container component to complete a deployment of the functional module.

A scheduler manages execution of a plurality of data-collection jobs, assigns individual jobs to specific forwarders in a set of forwarders, and generates and transmits tokens (e.g., pairs of data—collection tasks and target sources) to assigned forwarders. The forwarder uses the tokens, along with stored information applicable across jobs, to collect data from the target source and forward it onto an indexer for processing. For example, the indexer can then break a data stream into discrete events, extract a timestamp from each event and index (e.g., store) the event based on the timestamp. The scheduler can monitor forwarders' job performance, such that it can use the performance to influence subsequent job assignments. Thus, data-collection jobs can be efficiently assigned to and executed by a group of forwarders, where the group can potentially be diverse and dynamic in size.

Methods, systems, and other embodiments for protecting a shared resource in a data processing system are described herein. In one embodiment, when responding to a request that requires use of the shared resource, determine whether a previously established sleep period for the shared resource has expired. If so, determine a health status of the shared resource based on one or more of applying an asymptotic transform to a percentage of time that a processing unit is idle and applying a linear transform to a session count for the shared resource. Then, determine whether the health status is sufficient to permit responding to the request; and if not, (i) determining an appropriate sleep period for the shared resource, (ii) initiating a sleep state for the shared resource for a period substantially equal to the determined appropriate sleep period; and (iii) exiting the sleep state and responding to the request.

A method for managing data includes obtaining a workload generation request, wherein the workload generation request specifies a security compliant rule, in response to the workload generation request: selecting a first set of resource devices using a resource allocation master list, initiating a security compliance test on the first set of resource devices to obtain a security compliance result, making a first determination, based on the security compliance result, that the first set of resource devices meet a security compliance criterion, and in response to the first determination: storing a virtual certificate in a security compliance database based on the security compliance result, and allocating the first set of resource devices to a workload based on the workload generation request.

Methods, systems, and computer-readable media for resource usage restrictions in a time-series database are disclosed. Elements of a plurality of time series are stored into one or more storage tiers of a time-series database. The time series are associated with a plurality of clients of the time-series database. Execution of tasks is initiated using one or more resources of one or more hosts. The time-series elements represent inputs to the tasks. The tasks comprise a first task and a second task. A usage of the one or more resources by the first task is determined to violate one or more resource usage restrictions. Based at least in part on the usage, one or more actions are performed to modify the execution of the first task. The one or more actions increase an amount of the one or more resources available to the second task.

An integrated circuit includes a primary initiator domain (ID) circuit including having a processor core, a responder domain (RD) control circuit, and a reset controller. Secondary ID circuits, each include a processor core and a reset controller. RD circuitry is coupled to communicate with the primary ID circuit and the secondary ID circuits and includes RD resource circuits. The RD control circuit is configured to allocate each of the RD resource circuits to a first initiator domain consisting of the primary ID circuit or one of the secondary ID circuits, and when one of the secondary ID circuits enters a reset mode of operation, the RD resource circuit allocated to the one of the secondary ID circuits enters a reset while the remaining RD resource circuits are not affected by the reset.
