The error detected is a dead lock. Look at the end of output file :

...
MPI process (universe 0, rank 0) terminated by signal(36); Deadlock detected (dumped to core.7766)
mercure13: mpid: MPI process terminated by signal(36)

Josefine Ghattas worked on that. Changes are included in dyn3dpar on LMDZ cvs server.
Look at :

• ​dyn3dpar/parallel.F90
• ​dyn3dpar/mod_const_para.F90

Tests are under progress.

[mafoipsl]

Modifications in parallel.F90 and mod_const_para.F90 are avalaible through LMDZ CVS server under tag LMDZ4_V3_2.
