Problem with CCSDT(2) Q


Gets Around
Hi,

Any my attempt to use CCSDT(2)_Q leads to the program crash as follows:
    7   0.0000005387028  -0.0317705520981     0.0     0.1

Could you be so kind as to help with this?

There is no error to analyze ... did you get anything else?
Did you try to run through gdb

The program always crashes after

regardless of the Windows version, Cygnus or Mingw compiler, basic set, NWChem version 6.3 or 6.5.

(Unfortunately I do not know how to debug Unix program.)

CCSDTQ=y
Did you compile the code with CCSDTQ=y?

NWChem 6.3 - yes. And it works for CCSDTQ but not for CCSDT(2)_Q.
NWChem 6.5 - no.

What version of NWChem have you been using for this CCSDT(2)_Q case?
I'd rather deal with 6.5, thanks!

Gets Around
Both, and there is no difference in the time of the fall.

The following should address your current failure

cd NWCHEM_TOP/src
wget http://nwchemgit.github.io/images/Tcenxtask.patch.gz
gzip -d Tcenxtask.patch
cd tce
make
cd ..
make link

Please let me know if this makes your input to work in NWChem 6.5

Thanks, Edo

Thank you very much it works.
