[petsc-users] Serial solution of system in MPI FEM application

[Ivano Barletta]

Dear all,

I have an MPI FEM application with an elliptic problem that I
solve with PETSc. For debugging purposes I want to
let the master process to solve the global system.

Is there any simple way in PETSc to gather the distributed matrix
(the type is MATMPIAIJ) on a single MPI process?

Thanks,
Ivano
