Hi Weiguang,
I examined this issue and am positive that this is a bug in the intel_mpi/2018 module you are using (Intel Parallel_Studio_XE_2018, 2018.2.199).
The code works fine at this place with intel_mpi/2020 or OpenMPI (openmpi/4.1.1 tested 4.1.1) on your machine Cosma6. So either use the module intel_mpi/2020 or the module openmpi/4.1.1.
Best,
Volker

It seems that the program can not write group catalogues for this particular output redshift. I have checked several things: previous outputs are fine; there is no problem with my disk space or the memory cost; I have tried to tune several parameters, but it always hangs at the same step; the zoomed-in IC runs fine with GIZMO.
