Hi Matt,

I was making thin projections. Each output dataset (DD****) is about 14G. What are "multiple root level tiles"? I have 256^3 root grids...

I just submitted another job asking for more nodes. I will let you know how that goes (in two days).

Thanks!
Yuan

What operation are you doing, and how big is your dataset?  And, does
your data have multiple root level tiles?
