Techniques for preventing concurrent execution of an infrastructure orchestration service are described. Worker nodes can receive instructions, or tasks, for deploying infrastructure resources and can provide heartbeat notifications to scheduler nodes, also considered a lease. A signing proxy can track the heartbeat notifications sent from the worker nodes to the scheduler node. The signing proxy can receive requests corresponding to a performance of the tasks assigned to the worker nodes. The signing proxy can determine whether the lease between each worker node and the scheduler is valid. If the lease is valid, the signing proxy may make a call to services on behalf of the worker node, and if the lease is not valid, the signing proxy may not make a call to services on behalf of the worker node. Instead, the signing proxy may cut off all outgoing network traffic, blocking access of the worker node to services.

A computer-implemented method, a computer program product, and a computer system for optimizing workload placements in a system of multiple platforms as a service. A computer first places respective workloads on respective platforms that yield lowest costs for the respective workloads. The computer determines whether mandatory constraints are satisfied. The computer checks best effort constraints, in response to the mandatory constraints being satisfied. The computer determines a set of workloads for which the best effort constraints are not satisfied and determines a set of candidate platforms that yield the lowest costs and enable the best effort constraints to be satisfied. From the set of workloads, the computer selects a workload that has a lowest upgraded cost and updates the workload by setting an upgraded platform index.

Migration of quantum services from quantum computing devices to quantum simulators is disclosed herein. In one example, a quantum computing device executes a migration service that receives a system stress indicator from a system monitor that tracks a status of the quantum computing device and/or a status of qubits maintained by the quantum computing device. The migration service determines, based on the system stress indicator, that a quantum service running on the quantum computing device is to be migrated. Upon determining that the quantum service is to be migrated, the migration service retrieves a QASM file that contains quantum programming instructions defining the quantum service. The QASM file is then transmitted to a quantum simulator running on a classical computing device for failover execution. In some examples, the classical computing device then executes a simulated quantum service within the quantum simulator based on the QASM file.

A method for off-loading tasks between a set of wireless earpieces in an embodiment of the present invention may have one or more of the following steps: (a) monitoring battery levels of the set of wireless earpieces, (b) determining the first wireless earpiece battery level and the second wireless battery level, (c) communicating the battery levels of each wireless earpiece to the other wireless earpiece of the set of wireless earpieces, (d) assigning a first task involving one or more of the following: computing tasks, background tasks, audio processing tasks, and sensor data analysis tasks from one of the set of wireless earpieces to the other wireless earpiece if the battery level of the one of the set of wireless earpieces falls below a critical threshold, (e) communicating data for use in performing a second task to the other wireless earpiece if the second task is communicated to the first wireless earpiece.

An automated improving of quality of service of a data center. Transients of a power grid fed to a power supply unit are monitored by a probe. Information on transients is provided across an interface to a server of the data center. Based on characteristics of the transients, a reliability of the data center is subjected to automated updating. A request for migration of workload requiring a higher reliability than the updated reliability can be sent to a central management. When the central management has identified another data center that can meet the required reliability, the central management migrates or relocates the workload to the another data center.

An embodiment includes issuing an indication that a thread is a time-critical thread. The embodiment initiates an active partition migration, from a source server to a destination server, of a source partition on which the program is stored. The embodiment stores, during the migration, records of locations of pages in memory referenced by the time-critical thread. The embodiment detects that a migration threshold has been reached, indicative of a threshold portion of the migration being complete. Responsive to detecting the migration threshold, the embodiment performs a priority migration of the time-critical thread. The priority migration includes suspending execution of the time-critical thread at the source server, retrieving the records of the locations of the pages in memory referenced by the time-critical thread, and issuing a command to transfer content from the pages to the destination server. The embodiment also includes issuing a migration command to complete the migration.

Embodiments of systems and methods for platform framework communications are described. Participants of a platform framework are registered as providing operation of a plurality of hardware devices of an Information Handling System (IHS). A registration request is received, by the platform framework, from a participant providing operation of a hardware device, where the request specifies a handle for communicating with the participant in order to operate the hardware device. The handle for communicating with the participant in operation of the hardware device is provided to a second participant that has registered with the platform framework and registered as a user of the hardware device. An update to the handle used for communicating with the first participant is determined. The second participant is notified of the updated handle for communicating with the first registered participant in operation of the first hardware device.

Adaptive control of deadline-constrained workload migrations can include monitoring migrations of workloads forming a wave migrating from a source computing node to a target computing node. The monitoring can be performed in real time. The migrations can be performed by transferring image replications of each workload over a data communication network. Based on an expected bandwidth availability, a likelihood that a cutover deadline associated with the wave is exceeded prior to completing a migration of each of the wave's workloads can be predicted. Migration of one or more selected workloads can be suspended in response to determining that exceeding the cutover deadline prior to completing migration of each of the wave's workloads is likely.

Edge device task management by receiving an indicator corresponding to a first container running a task on a first edge device of a cluster of edge devices, wherein the indicator indicates an error status of the first container, and wherein task data of the task is stored in a first local storage of the first edge device, selecting a second edge device from the cluster of edge devices, wherein a second container on the second edge device is to run the task, instructing the first and second edge devices to transfer the task data from the first local storage of the first edge device to a second local storage of the second edge device, and in response to receiving a notification that indicates the task data has been transferred from the first local storage to the second local storage, sending the task to the second container.

Technology for interoperability is disclosed by enabling the sharing of user context or preferences for a computing experience across computing devices, operating systems, applications, or locations. A platform and application programming interface (API) are provided for computer applications and services to store and retrieve context data associated with a computing experience. Access to the context data for sharing may be managed by an access controller, which enables a user to manage access permissions for the sharing of the context data. The context data may be defined according to a common schema, which specifies the information for sharing and may be communicated using common communication channels or protocols. Thus context data may be shared across nearly any application or service including those developed in different computer programming languages or operating on different types of computing devices or devices running different operating systems or by different software developers.
