[Pw_forum] cholesky decomposition

[alan chen]

Dear PWSCF users,
     When I calculate a large system (320 atoms in the super cell), I get
the following error message:
      from  pzpotrf  : error #       452
      problems computing cholesky decomposition
      I calculate the same system with fewer atoms, there is no such
problem. Is it because the system becomes too large? What is the maxmium
number of atoms in the super cell PWSCF can calculate stably?
      Thank you very much.
