+    title: "Individual time-stepping in cosmological simulations: A challenge for strong scaling and domain decomposition algorithms"
+    author: Matthieu Schaller
+    abstract: "For many decades cosmological simulations have used individual time-steps for the particles (or cells) that are evolved forward in time. Given the large range in time-step sizes
+    required for accurate integration, this allows substantial gains in time to solution compared to the more widely adopted in science technique of using a single time-step for the whole
+    computational domain. However, only limited work has been done to improve domain decomposition techniques to make them aware of this multiple time-stepping scheme. This results in domains
+    perfectly suited for time-steps where most particles require updating but leads to terrible performance with large levels of imbalance for the steps where only a small fraction of particles are
+    being updated. This generates poor overall strong-scaling performance and leads to a poor utilisation of the systems. 
+
+    In this paper, we will introduce some of these short-comings and present a solution based on task-based parallelism and a weighted graph domain decomposition algorithm implemented in the
+    open-source cosmological code SWIFT. By carefully weighting the different tasks in an overall cluster-wide graph, we can divide the work and not the data optimally. If we further penalise the
+    creation of communication tasks we can achieve a domain decomposition where no MPI communication is required for the time-steps with few active particles. This effectively eliminates most imbalance
+    issues and leads to optimal performance not just for time-steps with large number of updates but also for the ones with few particles to update. We achieve much better strong-scaling performance than
+    commonly used codes and achieve a time-to-solution 30 times smaller than the de-facto standard Gadget code."
