I noticed you never checked the return code from your MPI_File_read
statement. If you had used your own mpi() function, it would state
something like this:
MPI_FILE_READ(116): Cannot read from a file opened with amode MPI_MODE_WRONLY

Hello Luís,
You opened the file with write-only mode which causes the subsequent read
to fail - although I do not know why the error checking fails to see that.
If you change MPI_MODE_WRONLY to MPI_MODE_RDWR then your code works fine.
