I'm also not a big fan of adding boost. Like devreal already mentioned, boost will complicate things, especially on HPC systems. Put it on the agenda for the next meeting.

I'm on it.

How should a direct halo width specification look like? Lets say, you want a two element halo width in each direction, does it mean including diagonal elements or not etc....

Possible is a stencil spec generator for typical stencil pattern. E.g. a full stencil with a specified width. Maybe this could be something you are looking for.

Hi Goon83, The halo width is based on the stencil spec. But i think it should be possible to also provide the width. I'm interested in your use case. The...

> But, I think the read with halo might be better served by the array created with halo layer. Otherwise, each access to halo layer may trigger a communication and...

Hi Bin, here is an example: https://github.com/dash-project/dash/blob/development/dash/examples/ex.02.matrix.halo.heat_equation/main.cpp Within the iteration loop you can see how to use the iterator. If you use the feat-halo branch the comment in line 145...

> @dhinf Can we merge this branch into development? I need to clean up some code. I think at the end of this week or next week we can merge...

> 1. The iterator (value_at(...) ) on both inner/boundary are 1D-index based. How is the 2D Stencil mapped onto the 1D value_at based one? Any layout changes, or duplication exits?...

Hi Bin, > for(auto it = current_op->inner.begin(); it != it_end; ++it) works on A > for (auto it = current_op->boundary.begin(); it != it_bend; ++it) { works on all 0 elements...
