ricc2 optimization error in gradient step

[jbaltrus]

Dear all,

I am having similar problem to the reported just below my post with TURBOMOLE 6.3.1

When trying optimization it aborts in gradient step

[jbaltrus]

come to think of it there is no gradient file in the folder. that's odd. I have

$grad    file=gradient

in control files, I have all the rest of files in the folder generated but gradient file is absent

[jbaltrus]

even more strange if I run SP ricc2 job it aborts at the same spot

Hi,

whenever a program crashes for unknown reasons, I'd recommend to contact the support.

Typical sources of errors stem from:

• corrupt or incomplete restart files,
• too high memory settings in $maxcor and/or $ricore,
• too low user limits for memory, stack size, shared memory, etc.,
• memory limits are usually re-set by queuing systems themselves, adding ulimit or limit to a script that is submitted to the queue might have no effect.

Regards,

Uwe

in general it's all true and well known. I am talking about calculating RICC2/aug-cc-pVQZ CH4 molecule on a system that has been working for several years with TURBOMOLE installed no problem. so ulimit and other things are all behind, not sure why this thin is happening.

What happens at that particular step of ricc2? does it start creating those large scratch files?

[uwe]

Hi,

CH4 with symmetry? Perhaps the input is simply too small to run it in parallel on many CPUs?
For CH4 and frozen cores there are only 4 occupied orbitals in C1.

If you have less non-frozen occupied orbitals than CPUs, I am not sure if that will work in all cases. It usually does, though.

Did you also try the SMP instead of the MPI version? I just did MP2 gradients for CH4 with aug-cc-pVQZ on 8 CPUs in C1 and there were no errors.

Regards,

Uwe

[jbaltrus]

did MPI with C1 geometry and 1 frozen orbital. Will do SMP right now

[jbaltrus]

shockingly it worked, thanks Uwe

[uwe]

Hi,

on my systems the MPI version works too for this case. So I can not really say what happened with your job.

Admins recently have done some heavy lifting of scratch space, I used several definition of TMPDIR, maybe that helped

Hi all Turbomole users,

I'm trying to do an optimization (46 atoms, only H and O) with ricc2 module and I got an error in gradient step apparently but which not say others informations
the job.0 file give that follows:

reading orbital data $uhfmo_alpha  from file alpha .

 orbital characterization : scfconv=7

 all orbitals will be active in the correlation treatment

 reading orbital data $uhfmo_beta  from file beta .

 orbital characterization : scfconv=7

 all orbitals will be active in the correlation treatment
     time in RI-CPHF prep  cpu: 12.40 sec    wall: 13.34 sec    ratio:  0.9
error in gradient step


I don't understand cause I already managed ricc2 optimization before and I got this error only after increasing my atoms number,
Can somebody help me?
Thanks in advance,

Cheers,
