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. \section*{Acknowledgment} The research was carried out using computational resources of Resource Centre
