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 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

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)
