Hi Volker,

Sorry for this late reply, Cosma is just back online.
I have turned off ALLOW_HDF5_COMPRESSION and given it a try, but this does
not help.
All simulation data is saved in the cosma6
disk: /cosma6/data/dp004/dc-cui3/group-zoom/G4-test/
Please let me know if you can not access it.

Best,
Weiguang
