Gus,
In my case, I"m not concerned with PDEs but the "linear system solvers"
themselves,which PETSci gets from other packages? So for example, looking
over their table at:
 http://www.mcs.anl.gov/petsc/petsc-as/documentation/linearsolvertable.html
 I'd want the "dense" case and therefore PLAPACK, so now I know to google
PLAPACK.
I just want to solve a system of simultaneous linear equations within the
vernacular of C/C++.
Thanks,
Peter
