I have run WRF 4DVAR successfully with AMSU radiance data and GF prepbufr data. But when I tried to assimilate MHS and HIRS4 data the program terminates with the following error:
Fatal error in PMPI_Cart_shift: Invalid topology, error stack:
PMPI_Cart_shift(198)....: MPI_Cart_shift(comm=0x84000005, direction=0, displ=1, source=0x7fff49f1d4e8, dest=0x7fff49f1d4ec) failed
MPIR_Cart_shift_impl(42): No Cartesian topology associated with this communicator
I have tried to run both in serial as well as parallel mode in multicore single workstation as well as IBM cluster. But no success. I am using WRF 4DVAR version 3.7. rsl file is attached with it.
