But if you say a = x + y, the move constructor will initialize that (because the expression x + yis an rvalue), so there is no deep copy involved, only an efficient move. that is still an independent object from the argument, but its construction was trivial, since the heap data di...

Stack-allocation is not an option for us as we want to keep the heap-allocated vectors even after the pipeline ran. Update: I attached perf stats for the various executions with numactl. Interleaving/localalloc has no effect whatsoever (the QPI bus is not ...
