Performance
Gordon Bell Finalist at SC09 - GA Crosses the Petaflop Barrier
- NWChem petascale calculation
- GA-based parallel implementation of coupled cluster calculation performed at 1.39 petaflops using over 223,000 processes on ORNL's Jaguar petaflop system. Apra et al. "Liquid water: obtaining the right answer for the right reasons"
- Global Arrays is one of two programming models that have achieved this level of performance
