Community Science Exemplars in SEAGrid Science Gateway: Apache Airavata Based Implementation of Advanced Infrastructure [link]Website  doi  abstract   bibtex   
We describe the science discovered by some of the community of researchers using the SEAGrid Science gateway. Specific science projects to be discussed include calcium carbonate and bicarbonate hydrochemistry, mechanistic studies of redox proteins and diffraction modeling of metal and metal-oxide structures and interfaces. The modeling studies involve a variety of ab initio and molecular dynamics computational techniques and coupled execution of a workflows using specific set of applications enabled in the SEAGrid Science Gateway. The integration of applications and resources that enable workflows that couple empirical, semi-empirical, ab initio DFT, and Moller-Plesset perturbative models and combine computational and visualization modules through a single point of access is now possible through the SEAGrid gateway. Integration with the Apache Airavata infrastructure to gain a sustainable and more easily maintainable set of services is described. As part of this integration we also provide a web browser based SEAGrid Portal in addition to the SEAGrid rich client based on the previous GridChem client. We will elaborate the services and their enhancements in this process to exemplify how the new implementation will enhance the maintainability and sustainability. We will also provide exemplar science workflows and contrast how they are supported in the new deployment to showcase the adoptability and user support for services and resources.
