Detailed Description

This class implements the operators and virtual methods of the EFichier class as follows: there are as many files as there are processes, physically located on the disk of the machine hosting the master task of the Trio-U application (the process of rank 0 in the "all" group).

The master process reads one item at a time from each file and sends it to the corresponding process. The same applies to the methods for inspecting the state of a file.
