The presentation of this paper is clear and within the scope of the journal. However, the paper can be improved in the following ways: ,---- |1. It is better to clearly state the major contributions of this paper in the introduction. -`---- +`--- +In this work we develop a new parallel two-stage algorithm for large-scale clusters. Our objective is to mix between Krylov based iterative methods and the multisplitting method to improve the scalability. In fact Krylov subspace methods are well-known for their good convergence compared to others iterative methods. So our main contribution is to use the multisplitting method which splits the problem to solve into different sub-problems in order to reduce the communications and to implement both inner and outer iterations as Krylov subspace iterations improving the convergence of the multisplitting method. + + ,---- |2. Given that the focus of the paper is to provide a better solution on a well known problem with several well studied approaches. It is essential for the
