 In this particular example we are choosing to employ a \verb|HLG| data
 structure for sparse matrices on GPUs; for more information please
 refer to the PSBLAS-EXT users' guide.
 We then have to initialize the GPU environment, and pass the
 appropriate MOLD variables to the build methods (see also the PSBLAS
