  - * CG or the conjugate gradient method is an iterative type Krylov subspace
  - * method which is suitable for symmetric positive definite methods.
  - *
  - * Though this method performs very well for symmetric positive definite
  - * matrices, it is in general not suitable for general matrices.
  + * GMRES or the generalized minimal residual method is an iterative type Krylov
  + * subspace method which is suitable for nonsymmetric linear systems.

  * The implementation in Ginkgo makes use of the merged kernel to make the best
  - * use of data locality. The inner operations in one iteration of CG are merged
  - * into 2 separate steps.
