Some personal notes on the I/O library MPP_IO

The output file (logfile) is constructued in psmile_io_init based on the name of the application and the rank of the proc in this application. It has the form *.mpp.log*.

To have more informations, it is possible to activate the key debug in module mpp_mod_oa.

stdout() which allows to write in *.mpp.log.* is defined for all the pe.
stderr() which also allows to write in the file *.mpp.log.* is only defined for the master process root_pe.

The total number of processors if defined (in mpp_init) but it is necessary to define a pelist with the number of processors with (at least) one active grid, but this pelist must be known by all processes
