摘要： A method includes executing one or more applications in a deterministic execution environment and executing a plurality of background tasks in the deterministic execution environment. The one or more applications and the background tasks are executed in different time slots. At least one of the background tasks cannot be completed within a single time slot. The at least one of the background task is executed incrementally in multiple non-adjacent time slots so as to prevent the at least one background task from interfering with the execution of the one or more applications.

摘要： A method includes executing one or more applications in an execution environment. The one or more applications are capable of requesting allocation of memory during execution. The method also includes allocating a plurality of memory blocks in a heap to the one or more executing applications. The plurality of memory blocks are allocated sequentially in the heap to the one or more executing applications. In addition, the method includes deallocating the plurality of memory blocks during a single deallocation. Memory blocks in multiple heaps could be allocated to the one or more executing applications. A particular memory block in a particular heap could be allocated to a particular executing application by pushing an indicator identifying the particular heap onto a stack. The particular memory block is allocated in the particular heap based on the indicator, and the indicator is popped from the stack after allocation.

摘要： The present invention provides systems and methods for controlling associated processes in a process facility and, in particular, for distributing data among nodes of a real time process control system that controls the process facility. An exemplary real time process control system includes a plurality of sensors, controllable devices, and communication paths, as well as a computer system. The sensors and controllable devices are associated with various ones of the processes of the process facility, and the communication paths associate the sensors and controllable devices with the computer system. The computer system operates on data relating to the process facility, and distributes the data among the nodes thereof. The nodes are associated with one another by ones of the communication paths also. The computer system includes subscriber nodes that desire data associated with certain of the processes and a publisher node. The publisher node monitors subscription lists associated with the subscriber nodes and, in response thereto, selectively communicates instances of the data to the subscriber nodes using ones of the communication paths. The communication paths have data traffic capacities and the computer system controls data distribution using the publisher node to efficiently utilize such data traffic capacities.
