paralllel eigensolver# Computation - 科学计算

Does anybody happen to know any parallel eigensolver suitable
for following system?
The system I am dealing with is banded Hermitian, however
pretty big (size: thousands by thousands, band width:
several hundred). I need selected eigenvalues and eigenvectors.
Actually, I only need the lowest one.
I were using ZHBVEX in LAPACK, it satisfied by requirment well.
However, I have to reduce my grid size to make my problem get
a converged result. Thus I prefer to change to a Parallel
solver.
thx
