Abstract: A host computer has a virtualization software that supports execution of a plurality of virtual machines, where the virtualization software includes a virtual machine monitor for each of the virtual machines, and where each virtual machine monitor emulates a virtual central processing unit (CPU) for a corresponding virtual machine. A virtual machine monitor halts execution of a virtual CPU of a virtual machine by receiving a first halt instruction from a corresponding virtual machine and determining whether the virtual machine is latency sensitive. If the virtual machine is latency sensitive, then a second halt instruction is issued from the virtual machine monitor to halt a physical CPU on which the virtual CPU executes. If the virtual machine is not latency sensitive, then a system call to a kernel executing on the host computer is executed to indicate to the kernel that the virtual CPU is in an idle state.

Abstract: A system and method for selectively operating on changed elements, for example merging, in a software development environment are provided. A software project comprising one or more version-controlled software development objects, or elements, is associated with one or more defects recording changed elements in the software development environment. The system and method provide for automated merging of changed elements associated with defects tagged for forward merging into the software project, and association or tracking actions for changed elements associated with defects that are tagged as not to be merged. The process of automated merging is carried out using a master work list listing work items representing changed elements ordered chronologically.

Abstract: The management of software updates of a set of equipment of an aircraft system on the basis of instructions in a service bulletin, accessible in the form of commands.

If the result of executing said selected command conforms to an expected result, at least one restore command allowing the reconfiguration of said equipment to its configuration preceding the execution of said command is selected. If the result of executing said selected command does not conform to an expected result, at least one previously generated restore command is executed.

Abstract: A method for satisfying loader dependencies on a running embedded computing device is provided. When a software application is loaded on a running embedded computing device, one or more binary files are identified that need to be loaded in order to run the software application. A determination is made as to whether the identified binary files are stored on the embedded computing device. If one or more of the identified binary files are missing from the embedded computer device, one or more file storage devices are identified that contain the missing binary files. The missing binary files are obtained from the one or more file storage devices during runtime and used to complete the load of the software application.

Abstract: According to an aspect, a method for checkpointing in a hybrid computing node includes executing a task in a processing accelerator of the hybrid computing node. A checkpoint is created in a local memory of the processing accelerator. The checkpoint includes state data to restart execution of the task in the processing accelerator upon a restart operation. Execution of the task is resumed in the processing accelerator after creating the checkpoint. The state data of the checkpoint are transferred from the processing accelerator to a main processor of the hybrid computing node while the processing accelerator is executing the task.

Abstract: A third-party provider may integrate services with a customized enterprise-software tenancy via a tenant service context determined using an uncustomized data model and a tenant-customized data model from the enterprise-software provider. A difference map is generated for the tenant-customized data model with respect to the uncustomized data model, and is used to determine a mapped integrated-service data model, which facilitates integrating services with those of the enterprise-software provider. The mapped integrated-service data model is merged with the tenant-customized data model to obtain the tenant service context for the tenant. When a user provides an instruction to interact with the multi-tenant enterprise-software provider, the tenant service context is used to determine an action based on an interpretation of the instruction, and the enterprise-software provider is commanded to perform the action.

Abstract: A firmware update system is described that collectively handles secure firmware updates for hardware resources in a defined and consistent manner. The firmware update system may be configured to manage at least some firmware updates in a pre-boot environment (e.g., before an operating system is loaded). By doing so, the firmware update system exercises control over the updates and reduce entry points exposed to attackers. In one approach, update states are defined for hardware resources that are managed by the firmware update system. In a pre-boot environment, the update states for the managed hardware resources are set to enable firmware updates. The firmware update system may then detect and apply firmware updates available for the managed hardware resources. Update states may be set to disable before loading the operating so that firmware updates for managed resources are disabled outside of the secure pre-boot environment.

Abstract: Embodiments relate to building a downloadable application. In response to a request to build a downloadable application, a build system determines a set of resources used by the downloadable application. The build system reads this initial set of resources to discover other resources used by the downloadable application. The build system determines resource dependencies for the set of resources and the discovered set of resources, and creates a dependency data structure according to the resource dependencies. Using the dependency data structure, the build system determines a subset of the set of resources and the discovered set of resources to include in a module associated with the downloadable application.
