FFT objects should define isize and osize attributes #11

Open sbrisard opened 9 years ago

For scatter/gather operations, it would be useful if FFT objects defined isize and osizewhich would store the total size of the input and output arrays. Likewise, the displacement (in the MPI sense) would be useful.

In e6e5496, four new attributes were defined, which will ease MPI communications

isize : the number of elements in the (local) input array,
osize : the number of elements in the (local) output array,
idispl : the displacement (in the MPI sense) of the local input array wrt the global input array,
odispl : the displacement (in the MPI sense) of the local output array wrt the global output array.
