Description

It is currently not possible to influence the optimizer/compiler in its decision to distribute the memory among the different tasks.
A way to weight the different operators, or to prioritize them somehow would greatly help to improve the memory utilization (in terms of performance gain).

Probably we could also add an overbooking of memory.
