[Wien] Segmentation fault in Supercell Calculation

[Lan, Wangwei]

Dear Professor Marks:


I've check everything you have mentioned, they are all fine, nevertheless it still don't work. I think the input files are ok since I have no problem running in non-parallel mode.

I tried to make the supercell smaller (2x1x1), then it works. However, I don't know why that happens.

By the way, I have "ulimit -s unlimited " in my .bashrc file. I'v also adjusted the RKMAX and RMT before.


Sincerely

Wangwei Lan

You have what is called a "Segmentation Violation" which was detected by 4 of the nodes and they called an error handler which stopped the mpi job on all the CPU's.

This is normally because you have an error of some sort in your input files, any of case.in0, case.clmsum (and clmup/dn if you are using spin polarized).

1) Check that you do not have overlapping spheres and/or other mistakes.
2) Check your error files, e.g. "cat *.error". Are any others (e.g. dstart.error) not empty? Did you ignore an error during setup?
3) Check the lapw0 output in case.output0* -- maybe shows what is wrong.

There are many possible sources, you have to find the specific one.

Dear WIEN2k user:


I am using wien2k_14.2 on CentOS release 5.8. ifort version 12.1.3 with MKL.



After generating a 2x2x1 supercell with 30 atoms, I tried to do the scf calculation. However, I got some errors. I'v attached it at the end of this email. My wien2k was installed correctly. It works well for other calculations. It also worked if I run non-parallel calculation for supercell. I'v searched the mail-list, but can't find any solutions. Could you give me a hint on how to solve the problem? Thank you very much.

On lapw0.error shows:

MPI_ABORT was invoked on rank 18 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.

You may or may not see output from other processes, depending on

exactly when Open MPI kills them.
