Up to Specific issues in real coupled models
Hello everyone, I'm working on a coupled model of ICON + NEMO v3.6 + HD via OASIS3-MCT v4.0 (without XIOS) on the computing system Levante (DKRZ, Hamburg, Germany). The coupled model hangs at line: CALL MPI_COMM_Split(mpi_comm_global,icpl,1,newcomm,ierr) of subroutine oasis_enddef. I printed out the value of mpi_comm_local just before the call MPI_COMM_Split and saw the value of 9 for ICON model, meanwhile in debug.root.01 (for ICON): (oasis_init_comp) mpi_comm_local = 3 The values of mpi_comm_local printed for NEMO and HD models are all 3, like in debug.root.02 and debug.root.03, respectively. Within another coupled model COSMO-CLM + NEMO v3.6 + HD via the same OASIS3-MCT version, on the same computer, the values of mpi_comm_local are all 3, either printed by myself or in the debug.root files. Do you have any idea what would cause that hanging problem? Cheers, Ha
Dear Ha, I am not sure what is happening. You should have a look at how the initialisation calls oasis_init_comp, oasis_get_localcomm are implemented in both codes and compare. I suppose that the components of the coupled model are launched the same way in both case? Maybe you can reply by sending a mail to oasishelp@cerfacs.fr so that we can interact offline on this? With best regards, Sophie
