Features of GEM
Some Observations:
- a) GEM is an HPCC class problem as expected to need, for initial Green’s function models, some 107 elements and compute power of some 1-100 teraflop. Estimate comes from comparing GEM multipole with related astrophysics problems and the measured extrapolation of these.
- b) GEM is a relatively young field and is not as obliged as other fields to worry about legacy codes. It should be able to aggressively take advantage of the emerging distributed object web technologies.
- c) GEM has interesting mix of data and novel algorithms
