Hi, I am trying to use petsc4py and slepc4py to read a matrix that is distributed on several files, In which i save the non zero elements by specifiying three arrays (A, I, J) for Coeffs, rows and columns indices. I am currently using MUMPS and i simply read a file and pass the A,I,J arrays to MUMPS with each process. I am trying to do the same, however i am still confused how matrices are structured in PETSc and if its even possible to read n files and pass the matrix to PETsc to solve with slepc4py using atleast n processes.
Thank you very much for your time, Sohaib.
