Editorial: Science Gateways Applying Clouds, Grids and HPC

With IWSG 2014 we featured the sixth edition of the workshop series IWSG (International Workshop on Science Gateways). IWSG 2014 attracted over 30 participants from nine different countries and 25 submissions, which consists of 17 full papers and eight abstracts. Accepted full papers resulted in 25-minutes presentations and abstracts in lightning talks of 15 minutes. While the 15 accepted full papers are published in these proceedings, the abstracts will be published on the website. Additionally, the workshop featured two high-profile keynotes and an outstanding panel discussion on "Science gateways in the cloud era" performed by research leaders from academia and industry. The topics of the proceedings include fundamental enhancements in general features of science gateways like extended developments of the security of science gateways as well as novel developments to support science gateway developers, new approaches in workflow management and use cases from diverse research communities.
