In order to contribute to the success of the "International Conference on High Performance Scientific Computing 2015", the Web site HPSC 2015 has been constructed. A wide range of useful information has been provided to whom are interested in the conference that will take place in March 16-20, 2015.

Because the Web site is in the developing stage, there still exist some mistakes or inconvenience to users. All comments and suggestions are highly appreciated by the organizers who would like to give users a better Web site. Your opinions should be sent to the e-mail address hpsc2015@math.ac.vn.

We also would like to thank the Interdisciplinary Center for Scientific Computing (IWR), University of Heidelberg (Germany) for its wonderful working environment helping us so much to develop this web site. Thanks also go to the Faculty of Computer Science and Engineering, Ho Chi Minh City University of Technology (Vietnam) for its support.
