Support for keyboard and mouse GLUT callbacks for steering Fully integrated with Gvid. Current status: Current status Protocol for interactive events. Java plugin (GUP) --> Fusion Application key=value string Integration with MD Fully operational (Demo Manchester) Improve submission input parameters from MD (xml) Storage of filesIntegration work: Integration work Define new controls in Java plugin to manage new features in development Change the way of submitting application to store data.Spin Glass Model: Spin Glass Model Spin Glass problem (Edwards-Andersson) with three dimensional spins of Heisenberg. Study of phase transition and critical values. Update of the system using HeatBath algorithm + Parallel tempering They are long simulations. Needed a lot of steps to stabilize the whole system. It would be helpfull some way of checkpointing (files generated) to restart application. Spin Glass Model: Spin Glass Model Interactivity not needed at the moment PACX-MPI most interesting feature of I2G. Pro: Simulation with great number of nodes. Con: The slowest WN is the maximun speed of whole system. Problem if checking beta != numProc +1 ???
