DA output question

[Amit.Itagi at seagate.com]

Randy,

In the general case, I may not have memory to scatter the entire gird to
the oth processor.  I guess, I will have to use the DA information to just
scatter the relevent portions.

Thanks

Rgds,
Amit

I simply scatter the DA vector to a natural vector on the 0th processor and
then output the grid, slice by slice, for example.
