No, you can only call them once for the entire program. Matt On Thu, Apr 30, 2009 at 1:25 AM, #DOMINIC DENVER JOHN CHANDAR# < [email protected]> wrote:

Hi,

I have a C++ code in which I plan to call PETSc for solving a system of equations. My doubt is regarding PETScInitialize() and PETScFinalize(). For example, I have a class called classX

classX {

public: initialize(); finalize(); };

classX::initialize() { PetscInitialize(...) .. .. more initializations.. }

classX::finalize() { PetscFinalize(); ... ... }

main() { classX ob1, ob2 ; // 2 objects

// Is the following acceptable ?? ob1.initialize(); ob2.initialize();

}

Do I need to call PetscInitialize() /PetscFinalize() for each object ?
