Abstract: The present disclosure relates to a processor that includes one or more processing elements associated with one or more instruction set architectures. The processor is configured to receive a request from an application executed by a first processing element of the one or more processing elements to enable a feature associated with an instruction set architecture.

Abstract: Example implementations relate to a upgrade of a host that hosts application units of a container-based application. According to an example, monitoring is performed to identify new system software component availability for the cluster. When a new system software component is available, a historical workload pattern of the cluster is analyzed to identify an upgrade window for each host of the cluster. When the upgrade window arrives for a host, it is determined whether reconfiguration of an application is to be performed based on a capacity of the cluster. When the determination is affirmative, a reconfiguration option for the application is identified and a configuration of the application is adjusted accordingly. The host may then be drained, removed from the cluster, upgraded, added back into the cluster and any application configuration changes can be reversed.

Abstract: The present disclosure generally relates to enabling migration of services between a first and second environment, while maintaining a local availability of those servers within the first environment. Specifically, embodiments enable the services to remain locally available with the first environment without modification of operation of clients within the first environment. A migration gateway is provided in the first environment that, on migration of a service from the first to the second environment, can announce availability of the service at the gateway. The gateway can then act as a proxy for the service in the second environment. In one configuration, the gateway adopts an Internet Protocol (IP) address of a server that has been migrated, such that clients may be unaware that migration has occurred.

Abstract: An engineering tool includes a hardware-allocation-data storage, an allocation-condition storage, and a tool processor. Hardware allocation data is to be downloaded to a controller that executes a host operating system (OS), and represents hardware allocation to each of the host OS and a guest OS that runs on a virtual machine implemented on the host OS. The allocation-condition storage stores therein hardware allocation conditions for the host OS and the guest OS. The tool processor causes a display to display a settings screen for inputting the hardware allocation data; after determining that the input hardware allocation data satisfies the allocation conditions stored in the allocation-condition storage, saves the input hardware allocation data in the hardware-allocation-data storage; and after determining that the input hardware allocation data fails to satisfy the allocation conditions, refrains from saving the input hardware allocation data therein.

In some examples, the nodes comprise online processing units (NPUs). In some examples, if a first node begins executing the task and fails, another node automatically takes over to ensure completion.

Abstract: An apparatus provides an issue queue having a first section and a second section. Each entry in each section stores operation information identifying an operation to be performed. Allocation circuitry allocates each item of received operation information to an entry in the first section or the second section. Selection circuitry selects from the issue queue, during a given selection iteration, an operation from amongst the operations whose required source operands are available. Availability update circuitry updates source operand availability for each entry whose operation information identifies as a source operand a destination operand of the selected operation in the given selection iteration. A deferral mechanism inhibits from selection, during a next selection iteration, any operation associated with an entry in the second section whose source operands are now available due to that operation having as a source operand the destination operand of the selected operation in the given selection iteration.
