I'am writing a small program where the process of rank 0 sends "alo alo" to the process of rank 1 and then process 1 will show this message on screen. I am using boost++ library but result stays the same when I use the MPI standard.
The program work locally ( that means: mpirun --host localhost), on the distant machine (mpirun --host name_of_distant_machine) but not on both ( mpirun --host localhost, name_of_distant_machine). There is no error message so i don't have any idea to resolve this.
The machine I am running is a virtual one, and the distant machine too.
Thank you in advance!
