Item Open Access On Fostering a Culture of Research Cyberinfrastructure Grant Proposals within a Community of Service Providers in an EPSCoR State(2015-07-30) Neeman, HenryOn Fostering a Culture of Research Cyberinfrastructure: Grant Proposals within a Community of Service Providers in an EPSCoR StateItem Open Access Developing a Hands-On Course Around Building and Testing High Performance Computing Clusters(2015-06-01) Morris, Mike; Frinkle, KarlWe describe a successful approach to designing and implementing a High Performance Computing (HPC) class focused on creating competency in building, configuring, programming, troubleshooting, and benchmarking HPC clusters. By coordinating with campus services, we were able to avoid any additional costs to the students or the university. Students built three twelve-unit independently-operating clusters. Working groups were formed for each cluster and they installed the operating system, created users, connected to the campus network and wrote a variety of scripts and parallel programs while documenting the process. We describe how we solved unexpected problems encountered along the way. We illustrate through pre- and post-course surveys that students gained substantial knowledge in fundamental aspects of HPC through the hands-on approach of creating their own clusters.Item Metadata only A Three-Semester, Interdisciplinary Approach to Parallel Programming in a Liberal Arts University Setting(2014-07-13) Frinkle, Karl; Morris, MikeWe describe a successful addition of high performance computing (HPC) into a traditional computer science curriculum at a liberal arts university. The approach incorporated a three-semester sequence of courses emphasizing parallel programming techniques, with the final course focusing on a research-level mathematical project that was executed on a TOP500 supercomputer. A group of students with varied programming backgrounds participated in the program. Emphasis was placed on utilizing the Open MPI and CUDA libraries along with parallel algorithm and file I/O analysis.Item Metadata only A Galërkin projection and multiple scales approach to Feshbach resonance in Bose-Einstein condensates(2006-11-27) Frinkle, KarlIn this paper, solutions of the nonlinear Schrödinger equation with a parabolic and a periodic potential modelling the dynamics of Bose–Einstein condensates are considered. A Galërkin projection approach is applied to reduce the partial differential equation to a system of nonlinear ordinary differential equations. In the case of Feshbach resonance, a multiple scales approach is applied to the reduced equations and is used to capture the dynamics of the full behavior of the PDE. Averaging is also used when the period of the oscillations corresponds to that of the difference in eigenvalues, thus inducing a resonance in the reduced equations. Accurate predictions of the overall behavior of the PDE can be made through this simplified model, including some very interesting resonance results.Item Metadata only The OneOklahoma Friction Free Network: Towards a Multi-Institutional Science DMZ in an EPSCoR State(2014-07-26) Neeman, Henry; Snow, Joel; Zimmerman, Brett; Runion, Matt; Louthan, George; Huebsch, Ed; George, Brandon; Gray, Zane; Brunson, Dana; Akin, David; Alexander, Joshua; Deaton, James; Fondjo Fotou, Franklin; Gentis, Debi; George, BrandonThe OneOklahoma Friction Free Network (OFFN) is a dedicated multi-institutional research-only "Science DMZ" network that connects the state's academic Cyberinfrastructure resources -- including all four high performance computing centers -- that is available for use by all Oklahoma academics plus their collaborators. A project of the OneOklahoma Cyberinfrastructure Initiative (OneOCII), OFFN is based on a collaboration of three universities, a nonprofit, and Oklahoma's research, education and government Regional Optical Network. OFFN consists of common configurations of Software Defined Networking infrastructure connected across a new set of optical links, at a minimum of 10 Gbps, and foreshadowing the state's transition to widespread 100 Gbps research connectivity. OneOCII, the parent initiative of OFFN, is a statewide collaboration to offer shared access to resources, both technology and human, to enable the use of advanced computing by research and education statewide. To date, OneOCII has served 52 academic institutions and 48 non-academic organizations.Item Metadata only The Oklahoma Cyberinfrastructure Initiative(2013-07-22) Neeman, Henry; Deaton, James; Gentis, Debi; Huebsch, Eddie; Brunson, Dana; Horton, David; Gray, ZaneThe Oklahoma Cyberinfrastructure Initiative (OCII) is a mechanism by which institutions in the state can share resources, both physical and human, to enable research and education statewide to utilize advanced computing technologies. OCII provides eight kinds of service: access to cyberinfrastructure; dissemination via an annual conference that has reached over 2500 participants in 11 years; education via a workshop series in person and via videoconferencing; faculty/staff development via summer week long workshops; outreach via a supercomputing talk suitable for non-technical audiences; proposal support in the form of both letters of commitment and direct collaboration; technology acquired for institutions or assisting those institutions in acquiring it; workforce development in the form of a mentorship program for Information Technology and Computer Science students statewide. To date, OCII has reached 50 academic and 47 non-academic institutions and organizations.Item Metadata only The Oklahoma PetaStore: A Business Model for Big Data on a Small Budget(2014-07-13) Neeman, Henry; Calhoun, Patrick; Akin, David; Zimmerman, Brett; Alexander, Joshua; Keller, Fred; George, BrandonIn the era of Big Data, research productivity can be highly sensitive to the availability of large scale, long term archival storage. Unfortunately, many mass storage systems are prohibitively expensive at scales appropriate for individual institutions rather than for national centers. Furthermore, a key issue is the set of circumstances under which researchers can, and are willing to, adopt a centralized technology that, in a pure cost recovery model, might be, or might appear to be, more expensive than what the research teams could build on their own. This paper examines a business model that addresses these concerns in a comprehensive manner, distributing the costs among a funding agency, the institution and the research teams, thereby reducing the challenges faced by each.
