Adjoint with MPI?

#1 Unread post by hjsong »

Hi,

I have a quick question.
Does adjoint model is available with MPI?
I tried to compile the adjoint sensitivity run with MPI, but it gave me an error.
(It successfully compiled with serial mode, though.)

Thank you!
Hajoon

Yes, the adjoint model can be run in serial and distribute-memory (MPI) but not in shared-memory (OpenMP).

You need to provide more information :idea: Unfortunately, we don't have divine powers to figure out what kind of errors did you got.

Dear Hernan,

In order to identify the error messages, I tried to compile it with MPI again.
But it worked at this time.

Sorry about the misleading posting.

Best,
Hajoon
