The rapid development of computing and communications technology has resulted in a great attention in high performance and smart computing (HPSC) in recent years. Both computing industry and research domain have a great demand of the high performance smart computing. HPSC has become one of the mainstreams of computing. As a key technology, smart computing is playing an important role in determining future research and development activities in many academic and industrial branches. High performance is another significant aspect when solving large and complex problems under a tight timing constraint. The HPSC 2015 is a research workshop cooperated with the 17th IEEE HPCC. This symposium provide engineers and scientists in computing domain with an academic forum in which the new research achievements, ideas, and results are shared. The state-of-the-art smart computing applications and experiences in high performance and smart computing will be represented in this academic event. HPSC-2015 is sponsored by IEEE, IEEE Computer Society, and IEEE Technical Committee on Scalable Computing (TCSC).
