[MITgcm-support] Raw binary output error when using MPI

Mon Aug 5 23:05:29 EDT 2024

Dear MITgcm community,I'm trying to run MITgcm in a new machine. However, there is something wrong in the raw binary output.I tried to run my case using mpi with 48 cores. However, the output files were not sperated into 48 subfiles, such as *.001.001.data/meta.Instead, the output file is just like *.data/meta. Thus, these output binary files can not been read by the provided code "rdmds" successfully.I'm not sure what causes this problem, could you help me check my code (presented below and also attached)? Thanks very much for your time!Best,Yanhong##### SIZE.h file in code/     &           sNx =   8,
