#SBATCH --error=test_ams-%j.err
#SBATCH --partition=tue.default.q

On some nodes, AMS is not running due to the processor type. Adding the following option the the AMS startup command might help:
-C "amd|haswell|cascadelake|broadwell"

AMSJob Python example
from scm.plams import *
gr = GridRunner(parallel=True, maxjobs=16, grid='slurm')
gr.settings.special.export = '--export='
job_settings = Settings()
job_settings.runscript.preamble_lines = [
'export SCM_TMPDIR=$SLURM_TMPDIR',
]
job = AMSJob(..., settings=job_settings)
job.run(jobrunner=gr, queue='myqueue.q', cores=16, nodes=1, C="amd|cascadelake|broadwell")
job.ok()
