Duplicate clock alarm error when using multiple blocks per MPI task

[YongjunZHENG]

I would like to use multiple blocks per MPI task. When set the following config in namelist.atmosphere

&decomposition
config_block_decomp_file_prefix = 'x4.163842.graph.info.part.'
config_number_of_blocks = 576
config_explicit_proc_decomp = .false.
/

and run atmosphere_model which 192 MPI task (3 blocks per MPI task), I got the following error:

ERROR: OOPS -- we have a duplicate alarmIDradtlw
ERROR:
ERROR: ------------------------------ FATAL CALLED ------------------------------
ERROR: subroutine physics_run_init: error creating radtlwAlarmID
CRITICAL ERROR: MPAS core_physics abort

It seems to add the clock alarm with the same ID for all the blocks of a MPI task.
Is there a quick way to fix this issue? Thanks.

The use of multiple blocks per MPI task isn't supported in MPAS-Atmosphere. Out of curiosity, what is your interest in doing so?

Thanks for your reply. I would like to implement the local time stepping (LTS) scheme to improve the efficiency for variable resolution configurations. The LTS has been implemented in MPAS ocean using multiple blocks for better load balancing.
