Re: [FRIAM] FW: Distribution / Parallelization of ABM's

[Douglas Roberts]

Well, first of all, Roadrunner will be a classified machine that will be used to do nuclear weapons research at LANL.  Secondly, the architecture of the machine is an extension of existing distributed memory cluster hardware that will hopefully leverage compact blade configurations combined with Opteron-based cluster technology using hybrid chips for specialized number crunching.  In other words, it will not be a general-purpose machine; rather, it will require specially coded applications to take advantage of it.  It will also be a huge power hog.  Finally, if previous experience with experimental new HPC hardware at LANL is any judge, "Roadrunner" has a bumpy road ahead of it before it becomes a productive resource.

All of the Teragrid supercomputer centers (NCAR, NCSA, SDSC, PSC, ORNL, Purdue, Indiana, TACC, and UC/ANL) have large queues of jobs waiting to run on their available resources.  I suspect the need for HPC cycles that are being provided by these centers will not go away any time soon.

Soon to be centers for hobbyists and enthusiasts!  :-)
