Ensemble-based Virtual Screening with Relaxed Complex Scheme NAMD2 Amber NCI Diversity Set: 3.3 MB, 2000 compounds; Required at each site ZINC subset: 200,000. A few hundred MB Multiple targets: HA, NA subtypes Each target: 30~50 MD snapshots, 1~2 MB each AutoDock4 Simulation Data: hundreds of GB Docking Data: hundreds of MB Total data to date: ~5 TB in long term storage. Each experiment is about 1 Petaflops accumulative in computation cost.
