Will automatic techniques like concurrent garbage collection be more or less relevant at exascale?<br /> == Resource Management ==<br /> How can different runtime components cooperatively manage shared resources? For example, cores can be used to support computation, communication and resilience. <br /> == User directives ==<br /> How can a runtime support both user directives and automated adaptations in an integrated manner?<br /> == Relaxed Synchronization ==<br /> What role can &quot;relaxed synchronization&quot; play in exascale software e.g., allowing tasks to execute even in the presence of data races so long as the probability of wrong answers is shown to be (or made) low?<br /> == Transactional Memory ==<br /> What role can transactional memory and related ideas for optimistic concurrency play in exascale software? How about actors?<br /> == Runtime / OS interoperation ==<br /> What assumptions should exascale runtimes make about exascale operating systems?</div>
