APPT is a biennial conference on parallel and distributed processing. Its scope covers all aspects of parallel and distributed computing technologies, including architectures, software systems and tools, algorithms, and applications. APPT was originated from collaborations by researchers from China and Germany and has evolved to be an international conference. The past seven conferences were held in Beijing, Koblenz, Changsha, Illmenau, Xiamen, Hongkong, and Guangzhou, respectively. APPT'09 will be the eighth in the series. Following the success of the last seven conferences, APPT'09 provides a forum for scientists and engineers in academia and industry to exchange and discuss their experiences, new ideas, and results about research in the areas related to parallel and distributed processing.
