Test solvers on MatrixMarket collections.

This test is located in Tests/solver_test001

###Brief

Test solvers and tune parameters on huge set of public domain matrices.

##Description

This test will run solvers in serial against symmetric or non-symmetric real problems from Harwell-Boing collection, Sparskit collection, NEP collection, as well as University of Florida Collection, and other collections available from http://math.nist.gov/MatrixMarket/.

Main purpose of this test is to assess robustness of internal solver during development. During develpement no performance gain should be accepted if as a results of the gain solver robustness narrows.

Another purpose is to tune solver's parameters for the optimal performance on some subset of matrices.

##Arguments

The test have three parameters:

• [integer] Solver type
  • 0 - BiCGStab(L) with second order ILU preconditioner
  • 1 - BiCGStab(L) with second order Crout-ILU preconditioner with inverse-based condition estimation and reordering for diagonal dominance
  • 2 - Petsc solvers
  • 3 - Aztec solver from Trilinos
  • 4 - Aztec solver from Trilinos with Ifpack preconditioner
  • 5 - Aztec solver from Trilinos with ML preconditioner
  • 6 - Belos solver from Trilinos, currently no preconditioner
  • 7 - serial BiCG with second order ILU from ANI3D package
• [string] Path to matrix
• [string] Path to file with options for solvers, may be empty
• [string] Path to right hand side, may be empty. If empty right hand side is filled with ones.

##CMake tests

Will generate lots of solver_test001_* tests.

To activate testing with options file add SOLVER_TEST001_OPTIONS_FILE string with the absolute path to file.

#Status

Currently internal solver INNER_MLILUC is capable of solving 100% of the whole set on default parameters.
