Detailed Description
Initializer for linear algebra packages.
This class is a reference-counted singleton. We need control over the destruction order since the destructor calls PetscFinalize() which shuts down MPI. Thus, the LinAlgInit object must be destroyed after all other objects that do MPI calls in their destructor. This cannot be guaranteed without the reference-counting since this class is instanciated as a local variable in the main() scope of the applications.
The documentation for this class was generated from the following files:
- src/LinAlg/LinAlgInit.h
- src/LinAlg/LinAlgInit.C
