SW: The XSEDE BLAST Gateway: Leveraging Campus Development for the XSEDE Gateway
This paper describes an XSEDE Extended Collaboration Support Service (ECSS) effort on scaling a campus developed online BLAST service (BLASTer) into an XSEDE gateway bridging the gap between genomic researchers and advanced computing and data environments like those found in the Extreme Science and Engineering Discovery Environment (XSEDE) network. Biologists and geneticists all over the world use the suite of Basic Local Alignment Search Tools (BLAST) developed by the National Center for Biotechnology Information (NCBI) throughout the full spectrum of genomic research. It has become one of the defacto bioinformatics applications used in all variety of computing environments. BLASTer allows researchers to achieve those tasks faster and without expert computing knowledge by converting BLAST jobs to a parallel model. It handles all of the details of computation submission, execution, and database access for users through an intuitive web-based interface provided by the unique features of the HUBzero gateway platform. This paper details the core development of BLASTer for campus computing resources at Purdue University, some of its successes among the user community, and the current efforts by an ECSS scientific gateways project from XSEDE to include data-intensive use of resources like Wrangler at the Texas Advanced Computing Center (TACC) within the XSEDE network. The lessons learned from this project will be used to bring other XSEDE computing resources to BLASTer in the future and other programs like BLASTer to XSEDE users.

SW: TopoLens: Building A CyberGIS Community Data Service for Enhancing the Usability of High-resolution National Topographic Datasets
Geospatial data, also known as spatial data or geographic information, is data or information representing physical objects with an explicit geographic component on the surface or near-surface of the Earth. The increased volume and diversity of geospatial data have caused serious usability challenges to researchers in various scientific domains, which calls for a cyberGIS solution. To address these issues, this paper presents a cyberGIS community data service framework to facilitate big geospatial data access, processing, and sharing based on a hybrid supercomputer architecture. Through the collaboration between the CyberGIS Center at the University of Illinois at Urbana-Champaign (UIUC) and the U.S. Geological Survey (USGS), a community data service for accessing, customizing, and sharing digital elevation model (DEM) and its derived datasets from the 10m national elevation dataset, namely TopoLens, is developed to demonstrate the pipelined integration of big geospatial data sources, computation needed for customizing the original dataset for end user needs, and a highly usable online user environment. TopoLens provides online access to precomputed and on-demand computed high-resolution elevation data by leveraging the ROGER supercomputer. The need for building such services for GIScientists and the usability of this prototype service have been acknowledged in community evaluation.

SW: Anatomy of SEAGrid Science Gateway
The SEAGrid Science Gateway provides researchers and educators a unified access to computational resources in a seamless fashion. SEAGrid has evolved from Computational Chemistry Grid infrastructure and is celebrating 10 years of service to the community that initially provided computational chemistry tools. This scope has since broadened to encompass other areas of Science and Engineering. SEAGrid is built on the Apache Airavata science gateway framework. This paper describes the technical architecture and internal underpinnings of the SEAGrid Science Gateway.
