National Science FoundationMiddleware Initiative (NMI)

• Started in 2001 initially over 3 years “to create and deploy advanced network services that simplify access to diverse Internet information and services.”

• Provides a centralized location for important grid software.

• Current NMI package includes Globus, Condor, MPI-G2, and a new grid portal project called OGCEGrid (funding started Sept 2003).
