    摘要： A one writer, multiple readers, shared data table concurrent access process includes providing a plurality of data elements. The data elements include a serialization mechanism. A second data element is a table/array of elements. A third data element is an atomic, integer counter. Inserting a new element into the shared unsorted data table by a writer includes locking the table. Removing an element at a position in the shared unsorted data table by a writer includes locking the table, copying the table so that the element to be removed is at the end of the table, deleting the element at the end of the table, and unlocking the table. From the shared data table by a reader includes looping through all elements of the table, loading and caching each element of the table, and read-only processing each element of the table.

    摘要： A method, apparatus, and computer instructions for processing a data packet in an interpartition virtual network in the logical partitioned data processing system. A state of a first flag and a state of a second flag is identified in the data packet, in response to receiving the data packet at a first partition in the interpartition virtual network from a second partition in the interpartition virtual network in the logical partitioned data processing system. A checksum is selectively verified for the data packet based on the state of the first flag and the state of the second flag.

    摘要： An apparatus, program product and method to manage access to a shared resource by a plurality of processes in a multithreaded computer via a collection of atomic operations that track both the order in which requests that use a shared resource are received, and the order in which processing of such requests are completed after they are received. Dispatching of requests is effectively deferred until processing of all non-dispatched requests that were received earlier than a most recently completed request has been completed. In many instances, completion of processing of requests can be performed non-atomically, thus reducing contention issues with respect to the shared resource. Furthermore, dispatching of requests may be batched to reduce the overhead associated with individual dispatch operations.
