摘要： A device attachment request to attach a device to a container within a virtual machine is received. The virtual machine is monitored to determine whether the virtual machine is ready for a hot-plug of the device. An indication that the virtual machine is ready for the hot-plug of the device is received from the virtual machine. A device hot-plug operation is issued to cause the device to be hot-plugged to the virtual machine.

摘要： A method includes analyzing, by a processing device, a set of container images. Each container image of the set of container images is built by executing a container image file having a plurality of lines arranged in accordance with an execution order. The method further includes assigning, by the processing device, a frequency of change to each line of the plurality lines in view of the set of container images, and modifying, by the processing device, the execution order to obtain a set of modified execution orders by reordering execution of at least a subset of the plurality of lines in view of their respective frequencies of change.

摘要： A request to execute a workload that utilizes an amount of resources to be executed is received from a client device. Corresponding resources that are available at multiple nonuniform memory access (NUMA) nodes are received from one or more host systems. A particular NUMA node of the multiple NUMA nodes is identified in view of the particular NUMA node having available resources that are greater than the amount of resources to execute the workload. A scheduling hint is assigned to the workload that indicates that the particular NUMA node is to be used to execute the workload.

摘要： A method includes identifying, by a first instance of a service, a first number of data partitions of a data source to be processed by the service and a second number of instances of the service available to process the first number of data partitions. The method further includes separating the first number of data partitions into a first set of data partitions and a second set of data partitions in view of the second number of instances of the service, determining a target number of data partitions from the first set of data partitions to be claimed by each of the second number of instances of the service, and claiming, by the first instance of the service, the target number of data partitions from the first set of data partitions and up to one data partition from the second set of data partitions.

摘要： Write removal for solid-state drives can be managed. For example, a computing device can designate a space of a solid-state drive (SSD) for a write of container. The computing device can store the write for the container in the space in response to loading the container for executing the container. The computing device can determine an end to an execution phase for the container. In response to determining the end to the execution phase, the computing device can remove the write from the space of the SSD.

摘要： A system includes a cluster, memory, and processors in communication with the memory. The cluster includes nodes and an application programming interface (API) server. The processor is configured to receive a request to determine a state of maintenance availability of the cluster. Each of the plurality of applications installed on the cluster are discoverable, and a deployment metadata associated with each of the plurality of applications is retrieved. The deployment metadata for each of the plurality of applications is parsed to retrieve one or more installation rules associated with each of the plurality of applications. The one or more installation rules associated with a first application of the plurality of applications is correlated with the one or more installation rules of the plurality of applications to determine a set of conflicts for the first application. Next, a state of maintenance availability is determined based on the set of conflicts.

摘要： Systems and methods for inter-cluster deployment of compute services using federated operator components are generally described. In some examples, a first request to deploy a compute service may be received by a federated operator component. In various examples, the federated operator component may send a second request to provision a first compute resource for the compute service to a first cluster of compute nodes. In various examples, the first cluster of compute nodes may be associated with a first hierarchical level of a computing network. In some examples, the federated operator component may send a third request to provision a second compute resource for the compute service to a second cluster of compute nodes. The second cluster of compute nodes may be associated with a second hierarchical level of the computing network that is different from the first hierarchical level.

摘要： Methods and systems for transforming bytecodes using virtual artifacts are disclosed. In one aspect, a method is provided that includes receiving a build request to convert source code into a first bytecode. A first virtual artifact may be identified within the source code and it may be determined that a local repository does not store the first virtual artifact. A real artifact that corresponds to the first virtual artifact may be retrieved from a centralized repository. A bytecode transformation may be applied to the real artifact to generate a second bytecode and the second bytecode may be added to the first bytecode.

摘要： Method and apparatus for atomic file look-up. An atomic look-up operation (407) allows an application (405) to find out whether a file is opened atomically based on whether or not the file path is present in a file system namespace cache (406). If not, the file open request can be redirected, avoiding or minimizing impacts to the scheduling of various operations involved in executing an application. The request can be redirected by the application to a process that includes blocking point handling (408, 409). An operating system according to the present invention includes a file system (400) including a file system namespace (404), and an operating system kernel (402) is operatively connected to the file system (400). The operating system kernel includes the file system namespace cache and the atomic look-up operation.

摘要： An apparatus, system, and method to facilitate the creation and management of service composition candidates in a service-oriented architecture (SOA). In one embodiment, the method includes receiving user input pertaining to a composition candidate associated with service candidates in a SOA service model, and updating the SOA service model based on the user input.
