Deadlock using Cmpi.convertFile2PyTree with a wrong file name

[nicolasgruel]

Hello everyone,

I create this issue to share the problem encountered in ticket #11526 (https://elsa.onera.fr/issues/11526#change-379348).
It seems that the problem comes from Converter.Mpi methods. When you give a wrong file name in methods such as 'convertFile2PyTree' or 'convertFile2SkeletonTree', the calculation crashes but the job still runs.

The deadlock likely comes from the fact that processor 0 reads the file, then transmits the PyTree to other processors. With a wrong filename, processor 0 returns an error and the other processors wait for the PyTree, without returning errors.

You can find here a small case reproducing the problem, you can launch it using 'job_juno.sh' : /stck/ngruel/Public/11526

Thanks in advance,
Nicolas
