Multitasking Framework Accelerates Scientific Discovery

A visualization of the active site of the enzyme dihydrofolate reductase. OLCF staff worked with ORNL computational scientist Pratul Agarwal to integrate functional partitioning into his AMBER code, which he uses to sample rare conformations of proteins and enzymes. With FP, Agarwal can configure AMBER to analyze conformations on available…
