Riper displays non-positive definite matrix in cholesky decomposition

[saleheen_noman]

Hi!

I was trying to run a periodic single point calculation for a 4*4*4 Ru(0001) surface with an adsorbed moiety using riper module. I used SVP basis set for adsorbed moiety atoms and ecp fr Ru, I also included the auxiliary basis set as the manual suggested. The following specifies my cell information in the control file-

$cell
  10.87272 9.41606 21.50000 90.0 90.0 90.0
$periodic 3
$kpoints nkpoints 4 4 1

Since the manual didn't suggest anything different, I have the coord file as usual.

I'm also using a b-p functional and m3 grid size. I tried with SMP parallelization and ran the calculation on 24 cores, unfortunately after reading the MO's, here's where the calculation stops-

             +--------------------------------------------------+
              |              NUMERICAL INTEGRATION               |
              +--------------------------------------------------+
               
       Will use smaller grid during SCF iterations and a grid
       of size 3 for the last iteration.

       Stratmann/Scuseria renormalization.

Can someone help me with this? Thank you so much!

You probably used ECPs, Turbomole 7.0.1 neither supports ECPs nor metallic systems for periodic calculations. The new 7.1 version does both.
