Grid Job Submission

• Submit docking jobs on grid

• Analyze results with AutoDockTools

Molecular Dynamics Simulations

• Start with the crystal structure• Ligands (tamiflu), ions• Explicit solvent, 0.15M NaCl• 112,457 atoms

• NAMD2, Amber99 force field• 2 fs timestep, PBC, PME• SDSC Datastar Benchmark: 112

processors, 0.21 days/ns need fast interconnect between processors - not for grid

• Data: tens - hundreds of GB
