IFESTOS Linear Algebra User Specific Functionality

• Select the best algorithm for user’s linear system.

  • The KB expects a list of features (size, sparsity, type) and desired bounds for memory/execution time
  • The KB returns the name of algorithm, parameter values, and estimates for the needed resources including the machine configuration and an exemplar to explain its decision

• Verify some assumptions or answer domain specific questions

  • Are iterative solvers better than direct solvers for large systems?
  • Is CG an efficient method for non-symmetric systems?
  • What is the best method for FD symmetric systems?
  • What is the best method for FEM systems?
