A simple test that uses ILU preconditioner and UMFPACK factorization library:

    mkdir test-umfpack
    cd test-umfpack
    hex-ecs --example
    hex-ecs --input example.inp

Another test of MUMPS library:
    
    mkdir test-mumps
    cd test-mumps
    hex-ecs --example
    mpiexec -n 1 hex-ecs --input example.inp --lu mumps --mpi
    
Test of the KPA preconditioner:
    
    mkdir test-kpa
    cd test-kpa
    hex-ecs --example
    hex-ecs --input example.inp --preconditioner KPA

Test of the GPU preconditioner:

    mkdir test-opencl
    cd test-opencl
    hex-ecs --cl-list
    hex-ecs --example
    hex-ecs --input example.inp --preconditioner GPU

All these tests calculate T-matrices and cross sections for L = 0 total angular momentum at three different energies.
