Abstract

The CIPRES Science Gateway (CSG) provides browser-based access to computationally demanding phylogenetic codes run on large HPC resources. Since its release in December 2009, there has been a sustained, near-linear growth in the rate of CSG use, both in terms of number of users submitting jobs each month and number of jobs submitted. The average amount of computational time used per month by CSG increased more than 5-fold since its initial release. As of April 2012, more than 4,000 unique users have run parallel tree inference jobs on TeraGrid/XSEDE resources using the CSG. The steady growth in resource use suggests that the CSG is meeting an important need for computational resources in the Systematics/Evolutionary Biology community. To ensure that XSEDE resources accessed through the CSG are used effectively, policies for resource consumption were developed, and an advanced set of management tools was implemented. Studies of usage trends show that these new management tools helped in distributing XSEDE resources across a large user population that has low-to-moderate computational needs. In the first quarter of 2012, 30% of all active XSEDE users accessed computational resources through the CSG, while the analyses conducted by these users accounted for 0.7% of all allocable XSEDE computational resources. User survey results showed that the easy access to XSEDE/TeraGrid resources through the CSG had a critical and measurable scientific impact: at least 300 scholarly publications spanning all major groups within the Tree of Life have been enabled by the CSG since 2009. The same users reported that 82% of these publications would not have been possible without access to computational resources available through the CSG. The results indicate that the CSG is a critical and cost-effective enabler of science for phylogenetic researchers with limited resources.
