In this chapter, we explain our view on the benefits of using co-scheduling for high performance computing in the future. To this end, we start with the issues of the current situation and a motivation. Then we define what we see as the main requirements for co-scheduling. Finally, we list the challenges we see on the way to effective and beneficial co-scheduling in compute centers.
This way, we want to make the reader aware of the research required within the context of co-scheduling, and we want to prepare the stage for the following chapters which focus on specific parts of the general topic of this book. It should become clear that we are only at the start of the research that needs to be carried out for effective co-scheduling on current peta-, future exascale systems and beyond.
