Embodiments are generally directed apparatuses, methods, techniques and so forth to select two or more processing units of the plurality of processing units to process a workload, and configure a circuit switch to link the two or more processing units to process the workload, the two or more processing units each linked to each other via paths of communication and the circuit switch.

Example techniques related to portable playback device power management. An example implementation involves launching a power coordinator background process, the power coordinator background process having multiple client programs and establishing respective inter-process communication (IPC) mechanisms between the multiple client programs and the power coordinator background process. The implementation further involves receiving, via the established IPC mechanisms from the multiple client programs, messages indicating that the respective client program is ready to suspend, and determining that each client program of the multiple client programs is ready to suspend. The implementation further includes sending instructions to the operating system to kernel suspend. While in kernel suspend, the playback device detects a particular trigger to kernel resume and in response, performs a kernel resume.

According to one general aspect, an apparatus may include a branch prediction circuit configured to predict if a branch instruction will be taken or not. The apparatus may include a branch target buffer circuit configured to store a memory segment empty flag that indicates whether or not the memory segment after a target address includes at least one other branch instruction, wherein the memory segment empty flag was created during a commit stage of a prior occurrence of the branch instruction. The branch prediction circuit may be configured to skip over the memory segment if the memory segment empty flag indicates a lack of other branch instruction(s).

Embodiments involving core-to-core offload are detailed herein. For example, a processor core comprising performance monitoring circuitry to monitor performance of the core, an offload phase tracker to maintain status information about at least an availability of a second core to act as a helper core for the first core, decode circuitry to decode an instruction having fields for at least an opcode to indicate a start a task offload operation is to be performed, and execution circuitry to execute the decoded instruction to: cause a transmission an offload start request to at least the second core, the offload start request including one or more of: an identifier of the first core, a location of where the second core can find the task to perform, an identifier of the second core, an instruction pointer from the code that the task is a proper subset of, a requesting core state, and a requesting core state location is described.

A data processing system comprises a plurality of reconfigurable processors including a first reconfigurable processor and additional reconfigurable processors, a plurality of buffers in a shared memory accessible to the first reconfigurable processor and the additional reconfigurable processors, and runtime logic configured to execute one or more configuration files for applications using the first reconfigurable processor and the additional reconfigurable processors. Execution of the configuration files includes receiving data from the first reconfigurable processor and providing the data to at least one of the additional reconfigurable processors, and receiving data from the at least one of the additional reconfigurable processors and providing the data to the first reconfigurable processor.

A computer-implemented method of monitoring programmatic containers (containers) through executing a computer program in a kernel space is disclosed. The method comprises storing trace data in a memory buffer that is shared by the kernel space and a user space, the trace data being related to execution of a process associated with a container at an execution point of the process. The method also comprises retrieving container data related to the container through raw access of one or more kernel data structures when execution of the process is stopped. In addition, the method comprises storing the container data in association with the trace data in the memory buffer.

A memory module includes a device controller that communicates with a host device based on a first interface including a first clock signal, a first data signal, and a first data strobe signal and operates in one of a first operation mode or a second operation mode depending on an operation mode control value from the host device, and a memory device that communicates with the device controller based on a second interface including a second data signal and a second data strobe signal. The device controller includes a logic circuit that transmits a predetermined training result value to the host device depending on a training control value from the host device, when a training is performed on a third interface being a virtual interface recognized by the host device in the first operation mode.

Examples are disclosed that relate to processing files between a local network and a cloud computing service. One example provides a computing device configured to be located between a local network and a cloud computing service, comprising a logic machine and a storage machine comprising instructions executable to receive, from a device within the local network, a file at a local share of the computing device, and in response to receiving the file, generate a file event indicating receipt of the file at the local share and provide the file event to a virtual machine executing on the computing device. The instructions are further executable to, based upon a property of the file, provide the file to a program operating within a container in the virtual machine to process the file, and send a result of executing the program on the file to the cloud computing service.

Described is a novel method of inter-process communication used in one example in a surveillance system whereby multiple input processes communicate surveillance data to a reader process that consumes the data from the input processes. A locking mechanism is provided to reserve a reservable portion of queue metadata which comprises queue pointer(s) such that only one process may move the queue pointer(s) at a time. Reservation is provided with little or no kernel operations such that reservation costs are negligible. Arbitrary size queue slots may be reserved by moving the points. Writing and reading into the queue is done outside of the locking mechanism allowing multiple processes to access and work in the queue simultaneously leading to a rapid queue synchronization mechanism that requires little or no resort to expensive kernel operations.

Techniques are provided herein for assigning pluggable database connections to thread groups. The techniques involve associating pluggable databases with thread groups. Each thread group is associated with a process running on a NUMA node. When a request for a connection for a pluggable database is received, the system determines which process on which NUMA node to spawn a thread for connecting to the pluggable database.
