Welcome to the proceedings of the ISPA 2005 workshops, held in the city of Nanjing, China. For the first time eight workshops were held in conjunction with the 3rd International Symposium on Parallel and Distributed Processing and Applications (ISPA 2005), to encourage interaction between researchers and practitioners. Workshop topics are, of course, in line with the conference s scientific scope and the workshops provided a forum for groups of researchers and practitioners to meet together more closely, to exchange opinions and advanced ideas, and to share preliminary results on focused issues in an atmosphere that fostered interaction and problem solving.
