Data efficient container for CutCellData

[ankithadas]

Dear AMReX team,

Is there any data containers (like MultiFab) that can store only SingleValued data? I know that MultiCutFab exists but it doesn't have most of the functionalities of MultiFab (eg FillBoundary). Would MultiFab work if I change the factory where only SingleValued fabs are allocated ?

Thank you in advance

Kind regards,
Ankith

Could you explain what functionalities you need? MultiCutFab does support ParallelCopy. It should not be hard to support FillBounary.

If you want to store only SingleValued data, you could put them into vectors. amrex::Scan::PrefixSum can be a useful tool.

We used to store cutfab's data in a compressed form and support communication. But the implementation was inefficient. So we changed to the current way. We do plan to do more works on EB in the near future. So maybe we will try again.
