F1850 f19g16 cesm1.2 program stucked

[dingnan0701@163_com]

cesm1_2_0 F1850 f19g16
The program stuck at Initialize ocn component OCN,but with no error in the log.
I instrument some print into the source code, find that the program stopped at shr_mpi_mod.F90, SUBROUTINE shr_mpi_bcastc0(vec,comm,string,pebcast) call MPI_BCAST(vec, lsize,MPI_CHARACTER,lpebcast,comm,ierr).

I also try F1850 T31g37 and F1850 f19f19 and F2000f19g16, the problem are the same!
And I have no idea how to fix it. CALL FOR HELP!! Thanks a lot.
my log is in the attachment.

First try updating to 1.2.2 and see if your problem has been resolved.   If that doesn't work let us know what compiler and mpi library you are using and we'll see if we can reproduce the problem.

HiI try cesm1.2.2, the problem remains the same.  My compiler is :mpiicc for the Intel(R) MPI Library 3.2 for Linux Version 11.0

I think that your compiler may be too old.   But it's difficult to tell - can you send the cesm.log output?

Many thanks. The log  is in the attachment. I am not sure it is the compiler's problem. I update the compiler to  icc version 14.0.2 mpi 3.2. It's  still not work.

If the program is hanging in an mpi_bcast it's becasue at least one process in the communicator is not arriving at the call.   I can't tell from your logs which it might be or why.    Try adding the task id to your debugging and see if you can figure out which process.
