Elemental implements, as opposed to wraps, the distributed-memory algorithms. In other words, it does not call any library like ScaLAPACK; it is an alternative approach. Elemental builds on top of BLAS/LAPACK/MPI in order to provide a nice interface to dense linear algebra on clusters/supercomputers.
The other major difference is that sequential libraries tend to get away with letting users not have to worry about where data resides. This is of fundamental importance in distributed libraries, and, for this reason, it is usually a bad idea to think of simply modifying sequential APIs.
