Unstructured open boundaries - release 4.0

[mgunduz]

I am testing the new release of nemo_4.0.
I am using one of the available regional configuration "SPITZ12".

When I activated the "ln_bdy", the models stop with the below MPI error message,
however, without an open boundary, the model runs perfectly!

I could not figure out the problem?

Fatal error in MPI_Recv: Message truncated, error stack:
MPI_Recv(224).....................: MPI_Recv(buf=0x8bd2cc8, count=21, MPI_DOUBLE_PRECISION, src=0, tag=2, comm=0x84000006, status=0x2984b90) failed
MPIDI_CH3U_Receive_data_found(131): Message from rank 0 and tag 2 truncated; 504 bytes received but buffer size is 168

which svn revision number do you have?
Do you have the bugfix [10630] in your code?

I can reproduce your error at revision [10606] (SPITZ12 runs with ln_bdy = .false. and does not run with ln_bdy = .true.)

Updating to the HEAD of release-4.0 (svn update), which as Sébastien says will include some bug fixes, solves the MPI errors I was getting from revision [10606]

Please confirm that it solves the issue you've raised.

Yes, with the above-mentioned bugfix the "ln_bdy = .true." is now working in SPITZ12 run!
