Description
I found a viscious error when trying to run NEMO on IDRIS/IBM SP6. It's perhaps due to the fortran compiler xlf version 13.1.0.3 recently installed on that machine.
Here is a list of 3 results obtained by the tests I made :
- ORCA2_LIM 2x2 domain decomposition : compilation OK, 1 year run OK
- ORCA2_LIM 4x4 domain decomposition : compilation OK, the model stops at the first time step with a segmentation fault in routine limthd_2.F90
- ORCA2_LIM 2x32 domain decomposition : compilation fails and gives back this error :
"/workgpfs/rech/fry/rfry154/NEMOGCM/CONFIG/ORCA2_LIM/BLD/ppsrc/nemo/limthd_2.f90", 1500-004 (U) INTERNAL COMPILER ERROR while compiling limthd_2_NMOD_lim_thd_2_. Compilation ended. Contact your Service Representative and provide the following information: Internal abort. For more information visit: http://www.ibm.com/support/docview.wss?uid=swg21110810
1586-346 (U) An error occurred during code generation. The code generation return code was 1"
The compiler seems not be able to interpret this fortran instruction in routine limthd_2.F90 :
(*) ztmp(:,:) = 1. - AINT( frld(:,:), wp )
When replacing (*) by
DO jj = 1, jpj
DO ji = 1, jpi
ztmp(ji,jj) = 1. - AINT( frld(ji,jj), wp )
END DO
END DO
everything works fine : the model compile and run whatever the domain decompostion is
