Hello,
I wrote a script which shifts a molecule on a graphene sheet surface and calculates Total energy. Everything seemed to work fine when just a few thousands of points are calculated but with a large number of calculated points I got this error message:

TremoloXCalculator: Cart_create with procs 1 1 1 and periods 1 1 1 failed
Traceback (most recent call last):
  File "traj_generator.py", line 222, in <module>
    total_energy = TotalEnergy(bulk_configuration)

tremolox.RuntimeError: SomeError: Error in file ../../../../src/comm.c, line 238 (0): SomeError: StartParallel: Cart_create failed

I am new to programming so I admit there might be an error in my script but I could not figure out what could be the source of this error message. Could anyone please explain this error message and direct me how to avoid it? I attached the full script.

Thanks a lot for any advice.

Hi,

This problem was known to appear in very rare cases, but should have been fixed in the QATK-Q-2019.12 version.
Which QATK version are you using?

Best,
Julian

Hi Julian,
thanks a lot for your help. It took me some time to get to it so sorry for a late reply. I used 2019.03 version but I tried it also with the new 2020.09 version and unfortunately I got the same type of error:

TremoloXCalculator: Cart_create with procs 1 1 1 and periods 1 1 1 failed

tremolox.RuntimeError: SomeError: Error in file ../../../../src/comm.c, line 238 (0): SomeError: StartParallel: Cart_create failed

Would you have any further suggestions what to do?

Thank you, Vaclav
