Abstract: A method, system, and computer program product that includes a processor assigning a network connection to an application, based upon the application requesting the network connection from a pool of network connections for connecting applications to a network resource, the assigned network connection for communicating a message with the network resource. The processor replaces the assigned network connection in the pool with a placeholder comprising configuration data of the assigned connection. The processor determined a period of inactivity of the assigned network connection, and the processor returns the assigned network connection to the pool, based upon the period reaching a defined threshold of inactivity.

Abstract: In a logic circuit having clocked state latches and combinatorial logic for functional processing of a task in response to functional clocking of the state latches, the state latches are additionally interconnected to form a scannable chain of latches, and task switching logic is provided for suspending task processing by interrupting the functional clocking of the state latches and, during such suspension, scanning the state latches such that existing contents of the state latches defining a task state can be saved from the state latches or new contents defining a task state can be loaded into the state latches. The invention provides an efficient means for switching tasks being performed by a logic circuit in a multiprocessing enviornment.

Abstract: Apparatus for serializing 2.sup.M parallel outputs of an all points addressable memory into successive data groups, with each data group corresponding to a respective value for a pixel in an image, wherein the bit-length of the pixel value is selectable. The apparatus includes a gate circuit having 2.sup.M parallel input junctions connected to the outputs of the memory and 2.sup.N output junctions. The gate circuit selectively converts each set of 2.sup.M parallel inputs at the input junctions in to 2.sup.M-n successive data groups, with each group having a bit-length of 2.sup.n bits. Each such group is transmitted to 2.sup.n of the 2.sup.N output junctions. A communication element conveys to the gate circuit a signal which controls the bit-length 2.sup.n of the data groups, wherein n is an integer 1.ltoreq.n.ltoreq.N.ltoreq.M.
