[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.
