Foil 6 Petaflop Performance for Flow in Porous Media?

From Overview of CFD and Numerical Relativity Case Study CPSP713 -- Autumn Semester 1994. by Geoffrey C. Fox


1 Why does one need a petaflop (1015 operations per second) computer?
2 These are problems where quite viscous (oil, pollutants) liquids percolate through the ground
3 Very sensitive to details of material
4 Most important problems are already solved at some level, but most solutions are insufficient and need improvement in various respects:
  • under resolution of solution details, averaging of local variations and under representation of physical details
  • rapid solutions to allow efficient exploration of system parameters
  • robust and automated solution, to allow integration of results in high level decision, design and control functions
  • inverse problems (history match) to reconstruct missing data require multiple solutions of the direct problem
