Various utility functions to work on Lists of Lists (usually resulting from 'gather'ing and combining information from individual processors)
- combine :
takes (elements of) sublists and appends them into one big list.
The access of data is through an AccessOp so that data can be 'gather'ed in one go, minimising communication, and then picked apart and recombined.
Example:
Combines sublists into one big list.
