Hi there,

I have got "dft optimize failed" after 200 steps running the following input with NWChem 6.1 and 6.0. Please can anybody advise what is wrong with the input as below. This case is running on Cray XE6.

echo
start co
title "co"
print medium

geometry
 C                     0.02130486    -0.67185363     0.00000000

 O                    -0.07773307     0.48364394     0.00000000
end

basis
 o   library "DZVP (DFT Orbital)"

 h   library "DZVP (DFT Orbital)"

 c   library "DZVP (DFT Orbital)"
end

driver
 tight

 maxiter 200

 xyz final
end

dft
 xc beckehandh

 mulliken
end

task dft optimize


Thanks,

Yudong

Did you want to remove the whole post or are you still looking for feedback.

No, I am still looking for feedback. My second post should be a new thread so I removed it from here.

Hi Yudong,

I have tried your input on my Redhat Linux box. I got the geometry optimization to converge in 5 steps to -112.58608241 Hartree without changing your input at all. I managed to get the same answer using both nwchem-6.0 and nwchem-6.1.1. So it seems that I cannot reproduce the problems you are seeing. Could you send me your output (hubertus dot vandam at pnnl dot gov), please? Maybe I can spot something.

Hi Huub,

I emailed the output file to you a few days ago. I think you may have received it.

Huub is in Europe right now, he should get back to you early next week.

Hi Huub,

Have you spotted anything wrong in my output?

Hi NWChem guys,

Please can you help me check if the input in the first post can work on your Cray XE6. It is not converging on our Cray XE6 with the same build of NWChem 6.1 as in my another post of "half int file".

Thanks,

Ysun

Nothing wrong in the input file
Ysun
I didn't have any convergence problem running your input file with NWChem 6.1 on the ORNL Cray XE6.

I would suggest you to try to complete your NWChem build (that I am trying to assist in the thread "half int file"),
and then try this input file again with that NWChem binary.

Cheers, Edo

Edo,

The dft optimize failed error still exists using the newly-compiled NWChem 6.1.1. The job is run on 32 cores. The last lines of the output are:

Does it fail at small core counts too?
Yudong,
Does the jobs fail when you run the job with a single core, too?

Edo,

It has got the same "dft optimize failed" error when running on a single core.

Please add "clear" to the driver section
Yudong,
Since Hessian that were left from previous runs might be causing your problem,
please add the clear keyword to the driver section, e.g.

driver

 clear

 tight

 maxiter 200

 xyz final

end

Edo,

The clear keyword has done the job. The simulation works fine now with NWChem 6.1.1.

Thanks,

Yudong
