1 PRAGMA Institute on PRAGMA 19 Wilfred W. Li, Ph.D., UCSD, USA Xiaohui Wei, Ph.D., JLU, PRC Hosted by JLU Changchun, Jilin, PRC, Sept 13, 2010 Avian Flu Grid: Transition from Grid to Cloud Computing

2 Scientific Driver and Use Cases Harris et al, PNAS, 2006

3 Relaxed Complex Scheme and Ensemble based Virtual Screening Contributed to HIV Integrase Inhibitor Development Exploration of the structural basis for this unexpected result … suggests an approach to the development of integrase inhibitors with unique resistance profiles. D. Hazuda et al., Proc. Natl. Acad. Sci. USA (Aug. 2004), refers to Schames, et al. (2004). Discovery of unexpected binding site in HIV-1 Integrase using MD and AutoDock: Schames, … & McCammon, J. Med. Chem. (released on web, early 2004) February, 2006 – Phase III Clinical Trials February, 2007 – Name announced: Isentress (raltegravir) October, 2007 – FDA fast track approval New Class of HIV Drugs: Merck & Co. MK-0518 Source: A. McCammon

4 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. Source: Amaro

5 Advances in Computing Infrastructure Enables Complex Simulations of Biomolecular Systems Amaro & Li, CTMC, 2010

6 New Challenges Virtualization – What does it mean to us? – Rockn Rolls, on demand virtual machines, Production environment – Where is it? What form should it take? – GPU clusters, virtual machines, cloud services Most work is still done on local clusters, the desire to use the grid/Cloud is there – Its happening, and quite exciting Collaboration – How to stay in touch better, PRIME, MURPA, research in general?

22 22 Vision Workflow Snippet Using Opal Two Major Steps 1.Run PDB2PQR web service. This step is skipped if an appropriate PQR file exists on the local machine. 2.Run PrepareReceptor web service. Output is URL to PDBQT PDB2PQR and PrepareReceptor are skipped if an appropriate PDBQT file exists on the local machine. – Output is PDBQT path on local machine. Macro that runs PDB2QR web service.
