With the rapid growth in computing and communications technology, the past decade has witnessed a proliferation of powerful parallel and distributed systems and an ever-increasing demand for practice of high performance computing and communications (HPCC). HPCC has moved into the mainstream of computing and has become a key technology in determining future research and development activities in many academic and industrial branches, especially when the solution of large and complex problems must cope with very tight timing schedules. The HPCC-2013 conference is the 15th IEEE International Conference on High Performance and Communications. It will provide a forum for engineers and scientists in academia, industry, and government to address the resulting profound challenges and to present and discuss their new ideas, research results, applications and experience on all aspects of high performance computing and communications. HPCC-2013 is sponsored by IEEE, IEEE Computer Society, and IEEE Technical Committee on Scalable Computing (TCSC). HPCC-2013 is the next event in a series of highly successful international conferences on high performance computing and communications (HPCC), previously held as HPCC-12 (Liverpool, UK, June 2012), HPCC-11 (Banff, Canada, September 2011), HPCC-10 (Melbourne, Australia, September 2010), HPCC-09 (Seoul, Korea, June 2009), HPCC-08 (Dalian, China, September 2008), HPCC-07 (Houston, USA, September 2007), HPCC-06 (Munich, Germany, September 2006), HPCC-05 (Naples, Italy, September 2005), HPCN-04 (Tokyo, Japan, December 2004), PACT-SHPSEC03 (New Orleans, USA, September 2003), PACT-SHPSEC02 (Charlottesville, USA, September 2002), HPCA-01 (Nova Scotia, Canada, November 2001), HPNCA-00(Delft, The Netherlands, May 2000), HPNCA-99 (Amsterdam, The Netherlands, April 1999).
