[petsc-users] Slepc reading distributed matrix from files

[errabii sohaib]

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.
