th This volume contains the papers presented at the 8 International Conference on - vanced Parallel Processing Technologies, APPT 2009. This series of conferences originated from collaborations between researchers from China and Germany and has evolved into an international conference for reporting advances in parallel processing technologies. APPT 2009 addressed the entire gamut of related topics, ranging from the architectural aspects of parallel computer hardware and system software to the applied technologies for novel applications. For this conference, we received over 76 full submissions from researchers all over the world. All the papers were peer reviewed in depth and qualitatively graded on their relevance, originality, significance, presentation, and the overall appropriateness for their acceptance. Any concerns raised were discussed by the Program Committee. The Organizing Committee did an excellent job in selecting 36 papers for presen- tion. In short, the papers included here represent the forefront of research from China, Switzerland, Germany, and other countries.
