PDSYEVX vs ad-hoc subroutineTurboRVB: Localized orbitals DFT + Quantum Monte Carlo for isolated and periodic systemStarting Hamiltonian from trial non orthogonal localized orbitalsIll conditioned symmetric matrix <strong>with</strong> a lot of eigenvalues close to zeroPDSYEVX require larger and larger working space and longer and longer time to convergeAd-hoc parallel subroutine using mixed <strong>MPI</strong>+<strong>OpenMP</strong>Slower for standard matrix but not dependent from the condition number,No additional working space.35
