Hello, I try to use external packages such as umfpack or superlu, which are listed here: http://www.mcs.anl.gov/research/projects/petsc/documentation/linearsolvertable.html
I have PETSc compiled and installed with those external packages. Presumably I think to use umfpack would be simply to specify an option in the command line arguments. However, I had a hard time finding the correct option. How can I look it up? Thank you. Best, Hui
