Research issues for executing real-time C3 applications on parallel processing systems
Robert Charles Metzger, John K. Antonio · 2002
Current trends indicate that future C3 (command, control, and communications) systems will likely contain suites of heterogeneous computing facilities composed of both parallel and sequential computing components. Also, 'commercial-off-the-shelf' components are being heavily considered for use in these future systems. In the context of these trends, brief overviews of related work within the areas of parallel processing and real-time computing are given and areas of future research are outlined. A central theme throughout the paper is that in order to make effective use of future C3 platforms, a significant amount of 'cross fertilization' between researchers in the parallel processing and real-time computing communities will be required. As an example of the need for combined expertise in both areas, the problem of how to effectively allocate real-time tasks onto the processing elements of a hypercube architecture is discussed. Other research issues, including the question of how to cope with the degree of nondeterminism present in many commercial parallel processing systems, are also discussed.>
