The Big Picture

Computation Chemistry Grid (CCG)“GridChem”

• A collection of “grid-enabled” resources to routinely run chemical physics applications

• Integrates a desktop environment into an infrastructure for a specific community of users– comp. chemists with large/small scale needs– experimental chemists who occasionally need

simulation capabilities to verify experimental results

• Establishes a distributed infrastructure for open scientific research– a virtual organization
