Fail when running CESM on cheyenne

Dear Cheyenne help friends,

I am trying to move from yellowstone to Cheyenne, given that the yellowstone is about to retire. I then downloaded the CESM1.2.2.1, logged in to Cheyenne, and created a new case. The case is successfully be compiled and built, but it failed when being submitted. The error message is copied as follows (cesm log in RUNDIR):

      1 MPT: Launch error on                          

  2 dplace: unable to execute ../bld/cesm.exe. No such file or directory

  3 MPT ERROR: could not run executable. If this is a non-MPT application,

  4 you may need to set MPI_SHEPHERD=true.


  6     (SGI MPT 2.15  09/03/16 04:16:39)


Can anyone help me understand what is going on? Many thanks!!

Hi Everyone, 

Just in case someone else also meet the same problem, I noticed that there is a bug in the script to generate [CASENAME].run code. There is one line like

mpiexec_mpt -p "%g:" omplace ../bld/cesm.exe >&! cesm.log.$LID

But there is no ../bld/cesm.exe under the ${RUNDIR}, where the command is ran. I then changed this line to 

mpiexec_mpt -p "%g:" omplace ${CASEROOT}/bld/cesm.exe >&! cesm.log.$LID

, and it works fine now.

BTW, if you want to change this in the CESM code to save your effort in the future, it can be done in CESM1_2_2/scripts/ccsm_utils/Machines/mkbatch.cheyenne.
