Title: State of XSEDE
Abstract - XSEDE has just wrapped up its first year of the program with a myriad of activities during that first year. In the presentation we will review the purpose and mission of XSEDE. In the spirit of the conference, "Bridging from the eXtreme to the campus and beyond," we will also review the expanded focus of the program with respect to the broad community it intends to support. Throughout the talk we will highlight some of the significant accomplishments of XSEDE in its inaugural year.

Title: Crisis In Higher Education: The Need For New Leadership
Abstract: Extreme growth in the nation’s Hispanic population, primarily Mexican American, is forcing educational challenges at a crisis level for the country. The problem is exacerbated by the fact that this fastest growing segment of the nation’s population continues to be the least educated. His warning is that the rate at which the minority population is growing outpaces the rate at which we are improving our effectiveness in educating this segment of the population. Because the economic health of the country is based in large measure upon technical advances, the country must find a way to incorporate this growing population into the mainstream of scientific and technical endeavors.
The speaker's remarks will focus on the successes and failures of the nation’s tier 1 universities regarding their representation at the undergraduate, graduate, and faculty levels in science, engineering, and mathematics. The speaker will also relate how he became a leader in underrepresentation issues at the campus, state, and national levels, and will discuss challenges he's faced throughout this journey.

Title - Stampede: Enabling more science with XSEDE
Abstract - When deployed in 2013, Stampede, built by TACC in partnership with Dell and Intel, will be the most powerful system in the NSF's eXtreme Digital (XD) program, and will support the nation's scientists in addressing the most challenging scientific and engineering problems over four years. Stampede will have a peak performance of 10 petaflops, with 272 terabytes of total memory, and 14 petabytes of disk storage. This presentation will provide an overview of Stampede and the innovative technologies that will enable more science for XSEDE users.
Speaker - Thomas Eickermann, Juelich
Title - PRACE - The European HPC Research Infrastructure
Abstract - PRACE - the Partnership for Advanced Computing in Europe is the European HPC Research Infrastructure.
Since its creation in 2010, PRACE has grown to currently 24 member states. It provides access to a set of high-end Tier-0 HPC systems in Europe for the European research communities a offers supporting services such as application enabling and training. The presentation will give an overview of mission, status and achievements as well as future plans of PRACE.

Speaker - Gayatri Buragohain, Feminist Approach to Technology
Title - Women, technology and feminism - reflections from India.
Abstract - The gender disparity in technical fields has been a concern throughout the world in recent times. Collating some inputs from eminent feminist activists and academicians from India who participated in a consultation on "Women and Technology" organized by Feminist Approach to Technology (FAT) last year, I will try to provide a feminist perspective on the need to mend this gender gap which looks beyond women's right to education and fair employment. I will do a comparison between status of women's participation in technical fields in India and the US to explain the similarity and differences between the challenges faced in the two countries. Lastly I would share some insights from the work that is being done in India to address this gender gap, including the work being done by my organization.

Title - Benefits and Challenges of High Spatial Resolution in Climate Models
Abstract - In three separate projects, the sensitivity of climate simulations to increasing spatial resolution was explored. This talk will summarize some of the benefits afforded by increasing resolution, as well as the challenges associated with large computations. In 2009-2010, the convergence of the outcomes from the World Modeling Summit and the windfall availability of a dedicated supercomputing resource at the National Institute for Computational Studies (NICS, an XSEDE partner) enabled a large international collaborative project called Athena to be undertaken. The objective of the project was to evaluate the value of dramatically increased spatial resolution in climate models, specifically with regard to changes in simulation fidelity and differences in projected climate change. The Athena team, composed of investigators from COLA, the European Centre for Medium-range Weather Forecasts, the University of Reading (U.K.), the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and the University Tokyo, in partnership with the computational science support team at NICS, confirmed that several important features of atmospheric circulation and precipitation are significantly better simulated when mesoscales are more accurately represented. The project also exposed a number of tensions that may be viewed as either problems or opportunities. This included insight into the challenges of handling a petabyte of data in a single project, with some prospects for the coming "exaflood".
In a separate project, a team of researchers from COLA, the University of Miami, the National Center for Atmospheric Research (NCAR) and the University of California at Berkeley, funded under the National Science Foundation PetaApps program and provisioned with supercomputing resources on Kraken, explored the roles of ocean eddies in simulations of climate. The possibility that noise in the climate system has an impact on predictability was specifically explored using a novel technique called "interactive ensemble" modeling. The volume of data generated in the project was very large and continues to be a valuable resource for understanding how ocean eddies can impact various features of climate variability.
In a third project, researchers from COLA and CSU, funded through the Center for Multiscale Modeling of Atmospheric Processes, an NSF Science and Technology Center, applied the novel technique of embedding cloud-resolving models in global climate model gridboxes, sometimes called super-parameterization, to a fully coupled global climate model. While the intent was to better represent very short time-scale processes associated with convective clouds, the representation of tropical variability on time scales of months and seasons to years was significantly improved. The computational challenges posed by accurately representing clouds in global models for climate time-scale simulations are described.
All three projects, while separately funded and composed of different multi-institutional teams of investigators, highlight the benefits and challenges of bringing high-end computing facilities - with their necessary complement of software, networks, and visualization tools - to bear on transformational computational science problems, as envisioned in the NSF CIF21 initiative.
