Detailed Description

Event that will collect the size in MBs used by each DataBox item on each parallel component.

Details

The data will be written to disk in the reductions file under the /DataBoxSizeInMb/ group. The name of each file is the pretty_type::name of each parallel component. There will be a column for each item in the DataBox that is not a subitem or reference item.
