Processing may be performed in accordance with a policy to assign roles of winner and loser between two nodes. The roles may be used in connection with deadlock resolution processing. A deadlock or potential deadlock may be detected between the two nodes performing processing for two transactions In response to detecting the deadlock or potential deadlock, using a current state may be used to determine whether to perform the deadlock resolution processing to resolve the deadlock or potential deadlock. The current state may indicate whether assignment of the winner and loser roles between the two nodes is in progress. Responsive to the current state indicating that processing is not in progress to assign roles of winner and loser between the two nodes, the current state may be used perform deadlock resolution processing to resolve the deadlock or potential deadlock. The current state may denote which node is the current winner.

Systems, apparatuses, and methods for implementing continuation analysis tasks (CATs) are disclosed. In one embodiment, a system implements hardware acceleration of CATs to manage the dependencies and scheduling of an application composed of multiple tasks. In one embodiment, a continuation packet is referenced directly by a first task. When the first task completes, the first task enqueues a continuation packet on a first queue. The first task can specify on which queue to place the continuation packet. The agent responsible for the first queue dequeues and executes the continuation packet which invokes an analysis phase which is performed prior to determining which dependent tasks to enqueue. If it is determined during the analysis phase that a second task is now ready to be launched, the second task is enqueued on one of the queues. Then, an agent responsible for this queue dequeues and executes the second task.

A method for online reconfiguration of a node in a process control system including components. Each component is a separate executable running in a separate operating system process as provided by a real time operating system of the node. A method is performed by a node manager of the node to be reconfigured. The method includes triggering, based on new configuration data and whilst running the at least one of the components to be reconfigured, creation of a new configuration entity for each of the at least one of the components to be reconfigured, the creating involving implementing, by each new configuration entity, a part of the reconfiguration corresponding to its component to be reconfigured. The method includes triggering synchronization of runtime data in each new configuration entity with runtime data of its corresponding existing configuration entity. The method includes triggering replacement of the existing configuration entity with its new configuration entity and thereby reconfiguring the node.

One embodiment provides an information processing apparatus effective to execute a parallel job in coordination with other information processing apparatuses. In an example, the information processing apparatus includes: a memory configured to store computer readable instructions; and a processor configured to execute the computer readable instructions sored in the memory, the computer readable instructions including: providing an instruction to issue barrier communication of error information; and propagating the error information to each of the other information processing apparatuses based on the instruction for the barrier communication.

A method for controlling the sending of data by a plurality of processors belonging to a device, the method comprising: sending a first message to a first processor of the plurality of processors to grant permission to the first processor of the plurality of processors to send a first set of data packets over at least one external interface of the device; receiving from the first processor, an identifier of a second processor of the plurality of processors; and in response to receipt of the identifier of the second processor, send a second message to the second processor to grant permission to the second processor to send a second set of data packets over the at least one external interface.

Apparatuses, systems, and techniques to implement a barrier operation. In at least one embodiment, a memory barrier operation causes accesses to memory by a plurality of groups of threads to occur in an order indicated by the memory barrier operation.

An apparatus includes an array processor to process array data in response to a set of macro-instructions. A macro-instruction in the set of macro-instructions performs loop operations, array iteration operations, and/or arithmetic logic unit (ALU) operations.

A computerized-method for identifying and utilizing effectiveness of agent handling multiple concurrent multi-channel interactions is provided herein. The computerized-method includes operating of a Multiple Multi-Channel Effectiveness (MME) module. The MME module includes: (a) operating an interaction module to retrieve one or more concurrent interactions of an agent from the data storage of interactions, according to a time range; (b) calculating an MME score for the agent based on metadata of the one or more concurrent interactions which defines the ability of the agent to handle multiple concurrent multi-channel interactions simultaneously; (c) storing the calculated MME score in the data storage of agents; and (d) sending the MME score to the one or more applications to take one or more follow-up actions based on the MME score.
