Files are not written for remote jobs

[Leimeroth]

When trying to submit Lammps jobs to a remote cluster only a .h5 file is created, but no input files or working directory. I guess somewhere during restructuring of run functions the necessary call to write_input has gone missing.

EDIT: For VASP it works, so the issue seems to be in the Lammps class.

[jan-janssen]

Can you try to call job.validate_ready_to_run() before submitting the job and check if that solves the issue?

[Leimeroth]

job.validate_ready_to_run() does not seem to change the behavior. Manually doing

os.makedirs(job.working_directory)
job.write_input()

seems to do the job.

[Leimeroth]

For potential that are manually defined via a dataframe the write_input_files_from_input_dict functionality breaks the remote setup because the filepath of the potential does not exist on the remote cluster.

Edit: I use https://github.com/pyiron/pyiron_atomistics/tree/workaround-file-copying as a workaround on the remote hpc right now. As far as I understand the idea of the new workflow is to copy only the hdf5 and write all necessary files on the remote machine, is this correct? If yes, I guess it is necessary to make an exception for potentials that are not part of the default data repository somehow. Also I am somewhat afraid of issues arising due to different pyiron versions/branches/whatever when only writing the files on the remote machine.

bump

[jan-janssen]

Can you be a bit more specific where the potential file is located /nfshome/leimeroth/MTP/AlCuZr/Fractions2//10/14//output.14.mtp is this on the cluster or on the local workstation?

[Leimeroth]

This is the full local path

Regarding file writing I guess the problem is

    def _check_if_input_should_be_written(self):
        if self._job_with_calculate_function:
            return False
        else:
            return not (
                self.server.run_mode.interactive
                or self.server.run_mode.interactive_non_modal

always returning False for lammps, so that

def save(self):
        """
        Save the object, by writing the content to the HDF5 file and storing an entry in the database.

        Returns:

        """
        self.to_hdf()
        if not state.database.database_is_disabled:
            job_id = self.project.db.add_item_dict(self.db_entry())
            self._job_id = job_id
            _write_hdf(
                hdf_filehandle=self.project_hdf5.file_name,
                data=job_id,
                h5_path=self.job_name + "/job_id",
                overwrite="update",
            )

            + str(job_id)
        )
        return job_id

does never call write_input

[jan-janssen]

Just as a workaround, can you check if it works by setting:

job._job_with_calculate_function = False

[Leimeroth]

With job._job_with_calculate_function = False the input and an additional WARNING_pyiron_modified_content file are written.

[jan-janssen]

With job._job_with_calculate_function = False the input and an additional WARNING_pyiron_modified_content file are written.

Does the remote submission work when job._job_with_calculate_function = False is set?

[Leimeroth]

Yes, the job is submitted and runs.

EDIT: The job runs and finished on the cluster. However, retrieving it with pr.update_from_remote() changes their status to initialized instead of finished locally.

[Leimeroth]

As the issue is not part of the Lammps class itself, I am confused why it works with VASP

[jan-janssen]

Ok, an alternative suggestion would be to add the write_input() call before the remote submission. I tried it in https://github.com/pyiron/pyiron_base/pull/1511 but have not tested it so far.

I do not know yet. We had another bug with how restart files are read https://github.com/pyiron/pyiron_base/pull/1509 but that is still work in progress.

Works with the addition of job.project_hdf5.create_working_directory(). Here the warning file is not created

Great, I think that is the best solution, until we have https://github.com/pyiron/pympipool ready to handle the remote submission.

[Leimeroth]

Do you have an idea how to fix the issue of potentials that are not part of the resources dataframe.

[jan-janssen]

I would modify the potential data frame, and maybe just attach the potential as restart file.

[jan-janssen]

@niklassiemer I close this issue, feel free to reopen it if the issue comes up again.

[niklassiemer]

Probably wrong ping @Leimeroth
