PaCT 2005 was jointly organized by the Institute of Computational Mat- maticsandMathematicalGeophysicsoftheRussianAcademyofSciences(RAS), theInstituteofComputationalModelingalsooftheRASandtheStateTechnical University of Krasnoyarsk. The purpose of the conference was to bring together scientists working on theory, architecture, software, hardwareand the solution of large-scaleproblems in order to provide integrated discussions on Parallel Computing Technologies. The conference attracted about 100 participants from around the world. - thorsfrom20countriessubmitted78papers.Ofthosesubmitted, 38paperswere selected for the conference as regular ones; there was also 1 invited paper.
