      abstract     = {In one of the most important methods in Density Functional
                      Theory – the Full-Potential Linearized Augmented Plane
                      Wave (FLAPW) method – dense generalized eigenproblems are
                      organized in long sequences. Moreover each eigenproblem is
                      strongly correlated to the next one in the sequence. We
                      propose a novel approach which exploits such correlation
                      through the use of an eigensolver based on subspace
                      iteration and accelerated with Chebyshev polynomials. The
                      resulting solver, parallelized using the Elemental library
                      framework, achieves excellent scalability and is competitive
                      with current dense parallel eigensolvers.},
