Hey! I am using PETSC in Fortran code and we apply the MPI process to parallelize the code.
At the moment, the options that have been used are -ksp_monitor_true_residual -ksp_type bcgs -pc_type bjacobi -sub_pc_type ilu -sub_pc_factor_levels 3 -sub_pc_factor_fill 6 Now, we want to use multiple GPUs and I would like to know if there is a better solver and preconditioner pair to apply in this case. Yours sincerely, Ramoni Z. S . Azevedo
