Hello,
Sorry for this bother. I"ve checked GMRES solver in your libary supports parallel computing in your website: http://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html.<http://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html> Summary of Sparse Linear Solvers Available from PETSc<http://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html> www.mcs.anl.gov Summary of Sparse Linear Solvers Available from PETSc Requests and contributions welcome As we all know the key algorithm inside GMRES solver is Gram-Schmidt process, so I guess if users specify their matrix A and right-hand-side vector b in a linear equation (Ax=b), the Gram-Schmidt process will be executed in parallel, including matrix-vector multiplications and orthogonalization between the basis vectors. Am I correct? Thanks very much. Best, Chih-Hao
