ScaLapack subroutine in a serial FEM code

[cfav]

Hello
I want to implement a subroutine that allows me to solve a linear system of equations in a parallel environment (cluster)

I have a serial FE code, and I want to know if I can have only ONE parallel subroutine that calls Scalapack parallel linear equations solver.

Specifically I want to know if I also need to apply any modification to the serial code to be able to run the whole program in an MPI environment.

Any response from you will be valuable for me. Many thanks in advance
Regards

Hi, did you find any answer to this? I too would be interested in knowing what are the steps to create a program that goes from sequential to parallel...
