Dear NWChem Forum members,
the goal of our study is the investigation of optoelectronic properties of small clusters such as AgnCo + . Therefore we use TDDFT calculations (within the CIS approximation) based on well-established functionals and basis sets (PBE0, HSE06, LC-wPBEh and cc-pvtz, def2-tzvpp). Starting with the structures we found to be the global mininum geometry, larger clusters with n > 4 seem to fail the convercence when solving the eigenvalue problem (Davidson iteration). This issue appears to be directly related to the number of excited states nroots specified in the TDDFT block. It has been tested successfully for "nroots 60", but somehow failed for higher values (see therefore an attached input file for "nroots 80"). Instead of showing an error message in the NWChem ouptut file, the job is immediately killed claiming an exceed of the memory limit (in an extra file generated by slurm, see below). We also tried to allocate more RAM in the NWChem input file without success.

Thus, did anyone of you experience a similar problem or has an idea of what may be the cause? Besides that we are interested in restarting TDDFT calculations in general. Are there possibilities for this?
Thank you very much in advance!
