Details of GEMCI - Core Infrastructure I

• Computational infrastructure involves link of geographically distributed observations and computation

  • Seismic sensors, SAR etc.
  • So hardware supports computation, data storage and access

• IGNORE Special Purpose Computers (such as GRAPE in Japan) for O(N2) particle dynamics which could for instance be used in Green’s function approach to equation solvers.

  • These have 100 times performance of “conventional parallel machines” but maybe there are much larger algorithmic improvements to be gained which require classic parallel computers

• Assume GEM simulations will use classic mix of computers from PC’s, Workstation. PC clusters, up to Origin/SP MPP’s

• Choose software (e.g. Fortran/C+MPI) supporting this range
