    29 Dec 2008 | | Contributor(s):: Mohamed Sayeed

    A basic introduction to Porting, Tuning and Performance analysis tools will be presented. I will talk about issues in porting applications to different architectures including writing portable programs. Application performance tuning is very important to making efficient use of high performance...

  13. MPI for the Next Generation of Supercomputing

    05 Dec 2008 | | Contributor(s):: Andrew Lumsdaine

    Despite premature rumours of its demise, MPI continues to be the de facto standard for high-performance parallel computing. Nonetheless, supercomputing software and the high-end ecosystem continue to advance, creating challenges to several aspects of MPI. In this talk we will review the design...

  14. Nanoparticle and Colloidal Simulations with Molecular Dynamics

    05 Dec 2008 | | Contributor(s):: Steve Plimpton

    Modeling nanoparticle or colloidal systems in a molecular dynamics (MD) code requires coarse-graining on several levels to achieve meaningful simulation times for study of rheological and other manufacturing properties. These include treating colloids as single particles, moving from explicit to...
