Ubuntu, HD7770, BLAS and APPML

Hi, I'm use GetDP (on Ubuntu 13.04) for solving large problems. GetDP was configured with PETSc and MUMPS. Usually, I use LU-decomposition as preconditioner for GMRES. For this, as default, using BLAS. In this time I try to use OpenBLAS (GotoBLAS) instead BLAS, it so much faster, but ... Can I use  GPU (HD7770) with APPML (clBLAS) instead BLAS(OpenBLAS/ATLAS) and CPU? If yes, how can I replace BLAS with APPML?
