Abstract:

We present the block-Jacobi EVD algorithm for large, dense,
Hermitian matrices which arise in various applications, e.g.
quantum chemistry and first principles molecular dynamics,
when the whole spectrum of a matrix is needed. The efficient
implementation on a parallel computer is discussed together
with the special dynamic ordering of subproblems. Finally,
the asymptotic quadratic convergence is proved both for the
serial and parallel algorithms.
