[Users] Error with CarpetIOHDF5 Checkpoint Iteration

[Wei Sun]

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,
