2. July 21, 2005 Interdisciplinary Modeling of Acquatic Ecosystems, Lake Tahoe 2 ACES State-wide research infrastructure development program funded by the NSF Experimental Program to Stimulate Competitive Research (EPSCoR) $3.4M ($1M/yr) in support of computational science activities in environmental research A collaboration between environmental scientists, computer scientists, and applied mathematicians at all three NSHE research campuses

3. July 21, 2005 Interdisciplinary Modeling of Acquatic Ecosystems, Lake Tahoe 3 Why environmental sciences? The area in which Nevada scientists have traditionally been the most competitive in securing funding Starting with an existing large community that supports excellent graduate level programs Environmental science disciplines are“data-intensive” (large observational data sets, intensive modeling application, need for advanced visualization tools)

4. July 21, 2005 Interdisciplinary Modeling of Acquatic Ecosystems, Lake Tahoe 4 ACES Main Objectives To create a core of computational science expertise and capability in environmental science research Foster application of Information Technology (IT) advances in environmental scientific disciplines Stimulate new multidisciplinary research centered on computer modeling and scientific data visualization

5. July 21, 2005 Interdisciplinary Modeling of Acquatic Ecosystems, Lake Tahoe 5 ACES Strategy Creation of the Nevada Environmental Computing Grid (NECG) - research infrastructure that is more than just a sum of individual components dispersed throughout the state Fostering scientific collaboration and growth of the Application Community at NSHE

6. July 21, 2005 Interdisciplinary Modeling of Acquatic Ecosystems, Lake Tahoe 6 Funding Opportunities for the Application Community Competitive postdoctoral (5) and graduate fellowships (14) in AY 2003/4 and 2004/5 - Congratulations Glenn! Summer 2005 graduate research program (13 fellows) Seed grants for development of new collaborative proposals and course development (4) - Congratulations Laurel! Matching funds for startup packages for new faculty in computer science and applied mathematics New faculty program for this fall

7. INFRASTRUCTURE Nevada Environmental Computing Grid (NECG) Three grid nodes (DRI, UNR, UNLV) with the main node and the core facility at DRI NNSC in Reno Utilizes the high-bandwidth network communication infrastructure of the Nevada Research Network (NRN) connected to Internet2 Two parts of NECG: –Computational Grid –Collaboration Grid (Access Grid)

8. July 21, 2005 Interdisciplinary Modeling of Acquatic Ecosystems, Lake Tahoe 8 ACES Web Portal The main entry point to all ACES resources Simple and unified access to technical documentation and job submission (using Globus Toolkit and Sun Grid Engine) Equally accessible from within or outside of DRI Expertise in using the grid portal future-proof Beta testing started in December ACES Survey questionnaire on the ACES web page!
