Abstract: Some embodiments provide a method for an application operating on a host machine. The method receives a configuration of a Dynamic Host Configuration Protocol (DHCP) service for implementation within a virtualized container on the host machine. The configuration includes several database table entries. The method converts the several database table entries into a configuration file for use by a process that operates in the virtualized container. the method initializes the process in the virtualized container. The process in the virtualized container reads the configuration file in order to perform DHCP services for machines connected to at least one logical forwarding element of a logical network.

Abstract: To provide a virtual resource control system capable of appropriately defining the amounts of allocated virtual resources to individual service systems under an environment in which service systems are added or deleted. A resource excessive/lacking amount calculation means 54 simulates a resource consumption situation of each node in the service system by use of a hybrid model, and calculates the amount of excessive/lacking resource indicating the lacking amount or the excessive amount of the amount of allocated virtual resource corresponding to one entire service system corresponding to a service management device. The resource excessive/lacking amount calculation means 54 notifies the amount of excessive/lacking resource to a hub device 60, and receives a notification of the new amount of allocated virtual resource corresponding to the entire service system. A notification by the resource excessive/lacking amount calculation means 54 and a response from the hub device 60 are made asynchronously.

Abstract: A method for executing a program in parallel includes creating a program replica, which includes a write operation on and an identifier of an object and is a copy of the program, for a thread. The identifier specifies whether the object is thread-local. The method includes modifying the write operation based on a speculation that the write operation uses only thread-local objects. The write operation executes in a transaction of the thread. The method includes determining, while executing the program replica and using the identifier, that the object used by the write operation is not thread-local, de-optimizing the write operation by adding instrumentation to implement a software transactional memory (STM) system for the write operation to obtain a de-optimized write operation, and performing the de-optimized write operation on the object to obtain a result and store the result in a redo log.

Abstract: A plurality of tasks are processed simultaneously in a plurality of CPUs. A task control circuit is connected to the plurality of CPUs, and when executing a system call signal instruction, each CPU transmits a system call signal to the task control circuit. Upon receipt of a system call signal from a CPU 0, the task control circuit 200 refers to a processor management register, identifies a RUN-task of the CPU 0, selects a READY-task that is to be executed next, switches process data of the RUN-task and process data of the READY-task, and updates processor management information.

Abstract: Controlling a software process by causing the execution of a first software process on a computer, where the first software process is configured to exclusively access a resource on the computer, causing the execution of a second software process on the computer when the first software process has exclusive access to the resource, where the second software process is configured to perform a first predefined action that is independent of the second software process accessing the resource, attempt to access the resource, and perform a second predefined action that is dependent on the second software process accessing resource, and causing the first software process to terminate its exclusive access to the resource, thereby causing the second software process to access the resource and perform the second predefined action.

Abstract: A host computer has a plurality of containers including a first container executing therein, where the host also includes a physical network interface controller (NIC). A packet handling interrupt is detected upon receipt of a first data packet associated with the first container If the first virtual machine is latency sensitive, then the packet handling interrupt is processed. If the first virtual machine is not latency sensitive, then the first data packet is queued and processing of the packet handling interrupt is delayed.

Abstract: A method for implementing an inter-virtual processor interrupt is provided, which includes: when a source virtual processor needs to trigger an interrupt to a target virtual processor, writing register data that includes information about the target virtual processor and indication data used to indicate that the source virtual processor triggers the interrupt to the target virtual processor into a virtual register of a virtual advanced programmable interrupt controller (vAPIC) of the source virtual processor, so that a virtual machine monitor obtains the information about the target virtual processor and the indication data from the virtual register by means of parsing, and the virtual machine monitor injects an inter-virtual processor interrupt into the target virtual processor according to the information about the target virtual processor and the indication data.

Abstract: A single workload scheduler schedules sessions and tasks having a tree structure to resources, wherein the single workload scheduler has scheduling control of the resources and the tasks of the parent-child workload sessions and tasks. The single workload scheduler receives a request to schedule a child session created by a scheduled parent task that when executed results in a child task; the scheduled parent task is dependent on a result of the child task. The single workload scheduler receives a message from the scheduled parent task yielding a resource based on the resource not being used by the scheduled parent task, schedules tasks to backfill the resource, and returns the resource yielded by the scheduled parent task to the scheduled parent task based on receiving a resume request from the scheduled parent task or determining dependencies of the scheduled parent task have been met.

Abstract: A hardware thread causes a SleepID register of a WAKEUP signal generation unit to store a SleepID that identifies the hardware thread when suspending a process due to waiting for a process by another CPU. The WAKEUP signal generation unit causes the WAKEUP data register of the WAKEUP signal generation unit to store a SleepID notified by a node when a process that the hardware thread waits ends. The WAKEUP signal generation unit outputs a WAKEUP signal that cancels the stop of the hardware thread to the hardware thread when the SleepIDs of the SleepID register and the WAKEUP data register agree with each other.

Abstract: A global-level manager access a work order from a client and parameters associated with the work order. A service level agreement to meet the work order parameters is determined. The service level agreement includes a price. An indication is received from the client that the service level agreement is accepted. The one or more input files are partitioned into multiple shards, and the work order into multiple jobs. The jobs are distributed among a plurality of clusters to be processed using underutilized computing resources in the clusters. The job outputs are combined to form the work order output. The jobs are monitored to insure that the deadline for completion of the work order will be met.
