Abstract: Concurrent threads may be synchronized at the level of the memory words they access rather than at the level of the lock that protects the execution of critical sections. Each lock may be associated with an array of flags and each flag may indicate ownership of certain memory words. A pessimistic thread may set flags corresponding to memory words it is accessing in the critical section, while an optimistic thread may read the corresponding flag before any memory access to ensure that the flag is not set and that therefore the associated memory word is not being accessed by the other thread. Thus, optimistic threads that do not have conflicts with the pessimistic thread may not have to wait for the pessimistic thread to release the lock before proceeding.

Abstract: Systems, apparatuses, and methods related to a virtual machine register in a computer processor are described. For example, a memory coupled to the computer processor can store instructions of routines of predefined, non-hierarchical domains. The computer processor can store, in the virtual machine register, an identifier of a virtual machine for which the processor is currently executing instructions in a current domain in the set of domains. For example, the processor can implement resource restriction/mapping and/or perform address translation for the virtual machine based on the identifier stored in the virtual machine register.

Abstract: A method for computing includes providing software source code defining a processing pipeline including multiple, sequential stages of parallel computations, in which a plurality of processors apply a computational task to data read from a buffer. A static code analysis is applied to the software source code so as to break the computational task into multiple, independent work units, and to define an index space in which the work units are identified by respective indexes. Based on the static code analysis, mapping parameters that define a mapping between the index space and addresses in the buffer are computed, indicating by the mapping the respective ranges of the data to which the work units are to be applied. The source code is compiled so that the processors execute the work units identified by the respective indexes while accessing the data in the buffer in accordance with the mapping.

Abstract: Virtual machines can be migrated between computing environments. For example, a system can receive a request to perform a migration process involving migrating a virtual machine from a source computing environment to a target computing environment. The target computing environment may be a cloud computing environment. In response to the request, the system can receive first configuration data for a first version of the virtual machine that is located in the source computing environment. The first configuration data can describe virtualized features of the first version of the virtual machine. The system can use the first configuration data to generate second configuration data for a second version of the virtual machine that is to be deployed in the target computing environment. The system can then deploy the second version of the virtual machine within one or more containers of the target computing environment in accordance with the second configuration data.

Abstract: Described herein are systems and methods for managing releases of global services in a controlled manner. A computing environment may include a first release of a global service, a second release of the global service, and a manager service. The first and second release may be enabled and disabled. The first release may be enabled and the second release may be disabled. The second release may be ready for use in the computing environment after passing one or more checks. A manager service may enable use of the second release in the computing environment. The manager service may disable use of (but maintain execution of) the first release in the computing environment. The second release may be determined to have one or more issues. Responsive to determining the second release has issue(s), the manager service may disable use of the second release and re-enable use of the first release.

Abstract: A function node control unit records a pair of an input message and a computer program as a journal log, and sends the input message and the computer program to a virtual machine unit. The virtual machine unit executes the computer program with the input message as an argument, and sends the execution result to the function node control unit. The function node control unit outputs the execution result as an output message. At the time of activation of the information processing device, a recovery unit restores the virtual machine unit to the state at a particular time in the past; sequentially fetches journal logs recorded after the particular time; causes the virtual machine unit to sequentially re-execute the computer programs with the input messages included in the respective journal logs as corresponding arguments; and roll-forwards the state of the virtual machine unit to the latest state.

Abstract: A cloud traffic migration system may be used to counter suspected harmful traffic. For example, a virtual machine (VM) may have a separate security and networking policy called a VM shell. The VM shell may be placed at the VM's interface as a layer of protection. When suspected harmful traffic is detected inside the VM, multiple mini VMs may be created that replicate some functions of the infected VM and the traffic may be grouped and segregated into categories. Each category of traffic may be routed to a mini VM for further analysis. Any traffic confirmed to be harmful may be kept inside the mini VM and subject to restrictive rules. Such restrictive rules may introduce delays to waste the attackers time or resources as well as obtain data for threat analytics.

Abstract: Methods and systems are presented for providing a container orchestration framework for facilitating development and deployment of software applications across different operating environments within an enterprise system. Upon receiving a service request for processing a set of data is received, the container orchestration framework determines one or more machines that store the set of data. Instead of processing the set of data remotely, the container orchestration framework deploys a container that encapsulates an application on the one or more machines. Each application instance running on the one or more machines are executed to process a corresponding subset of data stored on the machine locally. The container orchestration framework obtains the output data from executing the applications on each of the one or more machines, and present the output data as a response to the service request.

It is detected that that a first source container inside the container scope requires the first service of the first service instance. The first source container is connected to the first virtual container to enable the first source container to access the first service instance through the first virtual container.
