	SCHEDULE: NOV 11-17, 2006 Sustainable Adaptive Grid Supercomputing: Multiscale Simulation of Semiconductor Processing across the Pacific Session: Grid Applications Event Type: Paper Time: 2:00pm - 2:30pm Session Chair: Thilo Kielmann Author(s): Hiroshi Takemiya, Yoshio Tanaka, Satoshi Sekiguchi, Shuji Ogata, Rajiv K. Kalia, Aiichiro Nakano, Priya Vashishta Location: 20-21 Abstract: We propose a reservation-based sustainable adaptive Grid supercomputing paradigm for tightly coupled computations of considerable scale and duration on a Grid. The paradigm is demonstrated for an adaptive multiscale simulation, in which accurate but compute-intensive QM simulations are embedded within a classical MD simulation only when and where high fidelity is required. Key technical innovations include an embedded divide-and-conquer algorithmic framework to maximally expose data and computation localities for scalability, a buffered-cluster hybridization scheme to adaptively adjust MD/QM boundaries for accuracy, and a hybrid GridRPC+MPI programming approach to combine flexibility, fault tolerance, and efficiency. We have achieved an automated execution of the simulation on a Pan-Pacific Grid in total of 150,000 processor-hours, in which the number of processors changes on demand and resources are allocated/migrated according to both reservations and unexpected faults. The simulation results of SIMOX reveal a strong dependence of the oxygen penetration depth on the incident position.
