• KSP_HPDDM_TYPE_BGMRES - block GMRES

• KSP_HPDDM_TYPE_CG - Conjugate Gradient

• KSP_HPDDM_TYPE_BCG - block CG

• KSP_HPDDM_TYPE_GCRODR - Generalized Conjugate Residual method with inner Orthogonalization and Deflated Restarting

• KSP_HPDDM_TYPE_BGCRODR - block GCRODR

• KSP_HPDDM_TYPE_BFBCG - breakdown-free BCG

• KSP_HPDDM_TYPE_PREONLY - apply the preconditioner only
