nanoHUB.org online simulations and more Network for Computational Nanotechnology Summary nanoHUB is a cyberenvironement, science gateway, portal…for the computational nanotechnology community The nanoHUB middleware is build on 10 years of experience that started with the PUNCH middleware and now In-VIGO The nanoHUB is getting ready to use TeraGrid resources using a Condor-G resource handler, same could be done with OSG resources…a nanoHUB VO ? Acknowledgements: The In-VIGO middleware is being developed at the University of Florida ACIS Lab of Jose Fortes and Renato Figueiredo. nanoHUB integration and deployment is a partnership between Purdue University, University of Wisconsin (Alain Roy) and the University of Florida under NSF grant SCI Questions:
