\section{Conclusion}
+In the paper we propose a system architecture consisting of two tree
+hierarchies of entitites, mapped on each other, that simplifies provision of
+resilience to failures for parallel programmes. The resilience is solely
+provided by the use of hierarchical dependencies between entitites, and is
+independent on each layer of the system. To optimise handling failure of
+multiple cluster nodes, we use the hierarchy implied by the order of creation
+of subordinate entitities. The hierarchical approach to fault tolerance is
+efficient, scales to a large number of cluster nodes, and requires slow I/O
+operations only for the most disastrous scenario~--- simultaneous failure of
+all cluster nodes.
+The future work is to standardase application programming interface of the
+system and investigate load-balancing techniques, which are optimal for a
+programme composed of many computational kernels.
