Enhancing scientific workflows with secure shell functionality in UNICORE grids

The UNICORE grid technology provides a seamless, secure and intuitive access to distributed grid resources such as computational or storage related resources. In addition, its extensible character through application-specific plug-ins and its enhancements developed in various European-funded projects leads to the UNICORE technology that is used in daily production at many supercomputer centers and research facilities world-wide today. In this paper we present an enhancement that provides the dynamic capabilities of a secure shell terminal within the UNICORE grid technology while single sign-on remains. This enhancement allows the integration of the dynamic work-behavior of scientists, or existing scientific applications, to be more integrated into the usual workflow with UNICORE and therefore in collaborative grid environments. As a well-known tool in the scientific community, a secure shell terminal provides the most flexible way of working on remote systems that no graphical user interface or advanced tooling in grid computing can ever provide
