Creating master file fails sometimes

The current solution is to just re-run the integration (it will skip existing files and create missing files).

[...]

Shutting down client

yet the number of files is correct:

paleo@slurm-nice-devel2903:$ ls out/ACL9011001b_0022.h5 | wc -l
125

I suspect a latency between (a) the file creation within a SLURM node and (b) visibility from other hosts.
