Improving service time with a multicore aware middleware

One of the major advantages of communication middleware is its independence from the underlying hardware platform. This improves portability and interoperability, whereas following the mainstream trend of favoring abstraction over performance or execution optimization. However, for time sensitive applications, this lack of integration with the hardware may fall short as performance is lowered and attention to priority requests is not sufficiently differentiated. In this paper, we propose a middleware that has a higher degree of integration with the underlying hardware platform; it uses the mechanisms of the operating system to control the use of the processing cores, reserving them as needed for supporting differentiated service to higher priority invoking nodes or clients. Results show that our middleware improves the service time of high priority clients and it offers stable communication times.
