Grids and Cyberinfrastructure
Indiana University is enabling new types of research, pedagogy, creative activity, and community impact by building one of the world’s foremost research computing environments. This environment combines deep human expertise, robust systems and services, and advances in computer science and informatics to address the needs of researchers and their collaborators on the local, national, and international stage
At the heart of IU’s cyberinfrastructure are its robust and reliable systems and services provided by the Research Computing division of UITS. These are the tools that enable computing research experimentation and implementation, and which amplify the talents and visions of local and national researchers. IU’s cyberinfrastructure combines world-class supercomputing systems, storage systems, networking, and visualization systems with proven professional training, consultation, and support.
Provenance and Preservation in Cloud Computing: Karma
As data and workflow driven e-Science applications grow in scale in response to exploding resource availability through cloud and data center computing and storage, the amount of new data created similarly explodes. This talk introduces a general provenance collection tool for workflow driven science discovery systems that captures the provenance record of new data products and collections. The ongoing collaboration with Lilly Endowment, Inc. to bring provenance collection to the Lilly Life Sciences Grid (LSG) will also be discussed.
Building beyond LEAD: Impact, Education, and Future Plans
Linked Environments for Atmospheric Discovery (LEAD) is a highly successful NSF-funded largescale ITR project in cyberinfrastructure for adaptive, on-demand mesoscale meteorological research. This presentation discusses the impact LEAD has had on meteorology research and education, on the Teragrid through its role as a leading edge science gateway, on the advancement of cyberinfrastructure goals, and future technical and outreach plans as the project enters its final year.
Indiana University Data Center
The Open Grid Computing Environments Portal and Services: Software for Science Gateways, part I
The Open Grid Computing Environment is an NSF funded and IU-led collaboration of universities that develops, packages, and delivers software to support user environments, such as the TeraGrid. This demonstration includes an overview of:
The Open Grid Computing Environments Portal and Services: Software for Science Gateways, part II
PolarGrid Cyberinfrastructure: Delivering HPC to the South Pole
Delivering stable HPC indoors can be a challenge, but how about on a glacier? In this presentation learn how cyberinfrastructure — delivered by Indiana University and its partners — is changing polar research expeditions to Greenland and Antarctica, and how cyberinfrastructure is being used to process air- and ground-based synthetic aperture radar data that will help develop more accurate ice flow models.
Research at Indiana University for Reliable Petascale Performance
As the rate of increase of individual processor performance slows, the need to reliably and efficiently use larger and larger numbers of processors increases. With today’s top supercomputers exceeding one petaFLOP/second, the number of computational and network components has increased by hundreds of thousands per machine. With such a large number of components, the mean time between failures of the whole machine decreases dramatically. This presentation will discuss some of the research projects now ongoing at Indiana University that attempt to address this problem.
Fault Tolerance in High Performance Computing: MPI and Checkpoint/Restart
Modern HPC applications must be able to tolerate inevitable faults if they are to harness current and future HPC systems. Detecting and responding to such failures in distributed systems poses complex and intriguing research questions.
Facilitating Scientific Workflow with Lustre WAN
Since April 2008, Indiana University has been offering 360 terabytes of Lustre storage across the wide-area network for the support of research projects desiring to tie distributed resources together. This presentation will discuss the research IU’s Lustre WAN service has supported and the ways in which it has aided researchers in breaking new ground.
Planetary Simulations With the Data Capacitor
Using three-dimensional radiative hydrodynamic simulations, researchers in IU’s Department of Astronomy study the effect of gravitational instabilities (GIs) on the migration of giant planets in a massive protoplanetary disk. To accomplish this task, simulations are performed on Pople, the SGI Altix at the Pittsburgh Supercomputing Center via the TeraGrid, and the data written to IU’s Data Capacitor via Lustre WAN.
