XSEDE announces 2018-2019 Campus Champions Fellows

XSEDE announces 2018-2019 Campus Champions Fellows

XSEDE has selected five Campus Champions Fellows for the next year, studying everything from agriculture to computer science.

Five researchers from American universities will work with cyberinfrastructure and high-

performance computing experts from XSEDE and U.S. research teams to tackle real-world science and engineering projects over the next year in the 2018 Campus Champions Fellows program.


The 2018 cadre are current XSEDE Campus Champions, a collection of faculty, staff and researchers at over 200 U.S. institutions who advise others on their local campus on the use of high-end cyberinfrastructure, and have been doing so for the past 10 years. The goal of the Campus Champions Fellows program is to increase expertise on campuses by including Campus Champions as partners in XSEDE's Extended Collaborative Support Services (ECSS) projects, which provide vital domain expertise to interested researchers.

  • Peter Hawrylak, University of Tulsa with mentor Kate Cahill at Ohio Supercomputer Center:  "Workforce Development: Education"

    • The XSEDE education program seeks to expand a capable and innovative advanced digital resource workforce across the country by providing access to example programs, course syllabi, and computational science education materials as well as guidance from XSEDE's education staff. Through the education program, Champions may propose a project to help create a formal undergraduate or graduate minor, concentration, or certificate program at their institution. This requires working with the faculty to identify the courses that would be part of such a program, locating and testing computational projects that would become parts of those courses, and working with the appropriate academic committees to prepare the materials needed to obtain program approval.

  • Chet Langin, Southern Illinois University at Carbondale with mentor Lan Zhao at Purdue University:  "Understanding sustainability issues in the global farm-food system using a global gridded model of agriculture"

    • The challenge of attaining sustainability in the global farm-food system is quite daunting. By 2050, global population is expected to reach 9.7 billion persons placing further pressure on global agriculture. If left unchecked, extensive expansion in the global farm-food system could encroach on hotspots of threatened natural systems resulting in greater clearing of key forestlands and unsustainable withdrawals of water for irrigation. Climate change further compounds this problem as extreme temperature and precipitation dampens crop yields within and across countries. To untangle the complex food and environmental issues faced by the world's farm-food system, we developed a global gridded computational model of agriculture (SIMPLE-G: a Simplified International Model of agricultural Prices Land use and the Environment). This agricultural model is open-source, geospatial (around 36,000+ grid cells) and flexible enough to accommodate a wide variety of interdisciplinary assessment (climate impacts, water scarcity, biodiversity, terrestrial carbon stocks and food security). We have a version of the model implemented as a HUBzero tool and is hosted on MyGeoHub (

  • Xinlian Liu at Hood College with mentor Anand Padmanabhan at the University of Illinois at Urbana-Champaign: "Interoperating CyberGIS and HydroShare for Scalable Geospatial and Hydrologic Sciences"
    • CyberGIS and HydroShare are two NSF Sustainable Software Integration (SSI) projects that support separate but closely related domain science areas. Both projects move computation off the desktop into advanced cyberinfrastructure based on service-oriented architecture enabling computation on big data, avoiding platform dependency and software installation requirements and serving as gateways to high performance computing. Interoperability between the two systems will enable the coupling of data and multi-scale and multidisciplinary modeling capabilities from both communities and empower scalable geospatial and hydrologic sciences. As both projects grow to integrate big data analytics and advanced modeling capabilities, we face two major challenges in interoperability: 1. How to establish a user environment that seamlessly integrates distributed data, software, and computation from both CyberGIS and HydroShare in a sandbox where users can focus on domain research? 2. How to achieve interoperability features as extensible, reproducible, and reusable software solutions for scalable development, deployment, and operation in order to support broader collaboration of various multidisciplinary research in our communities?
  • Gil Speyer, Arizona State University with mentor Dmitry Pekurovsky at Sand Diego Supercomputer Center:  "Simulation for 2D Semiconductor with Parallel Uniform and Adaptive Multigrid Method for Multi-component Phase Field Crystal Models"

    • This renewal request focuses on the dynamics of oceanic double-diffusive convection, an important small-scale mixing process driven by the two order of magnitude difference in the diffusivities of heat and salt in seawater. One of the most distinctive features of double-diffusive convection is its tendency to form stacks of convective layers known as staircases, which are prominent in the Arctic at the transition between the cool water beneath the sea ice and the warm water of Atlantic origin. The reservoir of warm water in the Arctic would be sufficient to melt the sea ice in only a few years if not for the slow heat transport through these staircases; thus, it is critical to our understanding of global climate to know the thermal properties of staircases and how such properties depend on any external forces. Recently, our work has identified that shear can play an important role in the formation of staircases via double-diffusive instabilities, but little work has been completed to date on how the heat-transfer characteristics of staircases depend on steady or time-dependent shear. This renewal seeks to address that problem using numerical simulations performed on a finite-volume, MPI-based general circulation model (MITgcm)..

  • Mohammed Tanash, New Mexico State University with mentor Rich Knepper at Cornell University: "Cyberinfrastructure Resource Integration"

    • The XSEDE Cyberinfrastructure Integration (XCI) team seeks Campus Champions Fellowship applications for projects in bridging activities between a local campus or campuses and XSEDE resources. These can include creating workflow submission systems that send jobs to XSEDE Service Provider resources from campus, the creation of shared virtual compute facilities that allow jobs to be executed on multiple resources, data management for researchers with Globus Connect, the creation of local XSEDE Compatible Cluster Systems, or other projects that utilize tools which reduce barriers for scaling analyses from campuses to national cyberinfrastructure.

Accepted Fellows, with the support of their home institution, make a 400-hour time commitment and are paid a stipend to allow them to focus time and attention on these collaborations. The program also includes funding for two visits, each ranging from one to two weeks, to an ECSS, PI or conference site to enhance the collaboration.
