Hello,
I encountered an error with CarpetIOHDF5 when reaching the checkpoint iteration, which stops my job if I use too many nodes for parallel processing. I am wondering if this issue is related to the HDF5 library I used during building and if there is a way to resolve it. I utilized the bundled HDF5 from the toolkit itself.
The warnings I received are as follows:
*WARNING Level 1* from host d24cepyc083.crc.nd.edu, process 0, while executing schedule bin CCTK_CHECKPOINT, routine CarpetIOHDF5::CarpetIOHDF5_EvolutionCheckpoint in thorn CarpetIOHDF5, file /Cactus/configs/sim/build/CarpetIOHDF5/Output.cc:442: "Values for DISTRIB=CONSTANT grid variable 'TERMINATIONTRIGGER::watchminutes' (time level 0) differ between processors 0 and 95; only the array from processor 0 will be stored."

Best regards,
