I'll look into it. I had not considered a sparse representation but that might 
be a good solution to keep everything in locals.

Could you use a sparse representation for the electron positions
rather than a dense scalar grid?

Something like a list of positions, an octree, or some other adaptive
mesh might allow you to fit smaller sub-problems in each work-group
and merge these results back into the global representation with
more sequential access patterns...?
