Foil 9 Analysis of Computational Structure

From Master Set of Foils for GEM Computational Science Presentation GEM Workshop Santa Fe -- October 24-25 1997. by Geoffrey C. Fox


So basic computation is "long range" and O(N2) for N fault segments
We can compare with other classic long range force problems such as particle dynamics (chemistry, astrophysics) and vortex method in CFD
  • This problem is linear in independent variables fi(t)
  • The position of fault segments is irregular but roughly fixed
  • Force law is that of a "double-couple" (equal and opposite dipoles)
But we have the same essential computational feature that O(N2) terms will lead to high computational load which needs to be addressed somehow.
