Thank you very much.I've successfully submitted a simple test case with settings "-compset X". But when submitting another case, CSM execution failed.POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------------------------------------------------------------------------------ POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------------------------------------------------------------------------------ POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------------------------------------------------------------------------------ POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------------------------------------------------------------------------------ POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------------------------------------------------------------------------------ POP aborting... aborting in io_pio_ropen with invalid file ------------------------------------------------------------------------application called MPI_Abort(MPI_COMM_WORLD, 0) - process 0application called MPI_Abort(MPI_COMM_WORLD, 0) - process 3application called MPI_Abort(MPI_COMM_WORLD, 0) - process 4application called MPI_Abort(MPI_COMM_WORLD, 0) - process 5application called MPI_Abort(MPI_COMM_WORLD, 0) - process 6application called MPI_Abort(MPI_COMM_WORLD, 0) - process 7 POP aborting... aborting in io_pio_ropen with invalid file application called MPI_Abort(MPI_COMM_WORLD, 0) - process 2------------------------------------------------------------------------application called MPI_Abort(MPI_COMM_WORLD, 0) - process 1 Could that be a problem with input_data? Because when I ran 'check_input_data' command, it said "File status unknown: b.e11.B1850C5CN.ne30_g16.tuning.004.clm2.r.0026-01-01-00000.nc " and it's in my input_data path.
