It is our great pleasure to present the proceedings of the symposia and workshops on parallel and distributed computing and applications associated with the ICA3PP 2010 conference. These symposia and workshops provide vibrant opportunities for researchers and industry practitioners to share their research experience, original research results and practical development experiences in the new challenging research areas of parallel and distributed computing technologies and applications. It was the first time that the ICA3PP conference series added symposia and wo- shops to its program in order to provide a wide range of topics that extend beyond the main conferences. The goal was to provide a better coverage of emerging research areas and also forums for focused and stimulating discussions. With this objective in mind, we selected three workshops to accompany the ICA3PP 2010 conference: * FPDC 2010, the 2010 International Symposium on Frontiers of Parallel and Distributed Computing * HPCTA 2010, the 2010 International Workshop on High-Performance Computing, Technologies and Applications * M2A 2010, the 2010 International Workshop on Multicore and Mul- threaded Architectures and Algorithms Each of the symposia / workshops focused on a particular theme and complemented the spectrum of the main conference. All papers published in the workshops proce- ings were selected by the Program Committee on the basis of referee reports. Each paper was reviewed by independent referees who judged the papers for originality, quality, contribution, presentation and consistency with the theme of the workshops.
