Welcome to the proceedings of the 8th International Conference on Algorithms and Architectures for Parallel Processing (ICA3PP 2008). ICA3PP 2008 consist of two keynote addresses, seven technical sessions, and one tutorial. Included in these proceedings are papers whose authors are from Australia, Brazil, Canada, China, Cyprus, France, India, Iran, Israel, Italy, Japan, Korea, Germany, Greece, Mexico, Poland, Portugal, Romania, Spain, Switzerland, Taiwan, Tunisia, UAE, UK, and USA. Each paper was rigorously reviewed by at least three Program Committee members and/or external revi- ers, and the acceptance ratio is 35%. These papers were presented over seven technical sessions. Based on the paper review results, three papers were selected as the best papers. We would like to thank the many people who helped make this conference a successful event. We thank all authors who submitted their work to ICA3PP 2008, and all Program Committee members and additional reviewers for their diligent work in the paper review process ensuring a collection of high-quality papers.
