Oggetto: Problems computing cholesky
Dear all,
I am facing a problem with the widely discussed error "problems computing cholesky".
I searched in the mailing list archive, but I couldn't find a solution to my problem.
After successfully running an "scf" calculation, I run a "bands" calculation which gives this error while computing the kpoints:
Computing kpt #: 1
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Error in routine cdiaghg (245):
problems computing cholesky
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
This problem arises with both 5.0 and 5.1 versions. Doing some tests, I found that if I decrease ecut and kpoints to ridiculously small values, the error doesn't show up.
Any advice is welcome!
Kind regards,
--
