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

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)

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

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

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

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)

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!
