Distributed computing management

Management of distributed computing systems is required, for example, to carry out activities using shared resources such as computational tasks, in-silico experiments and other tasks. In an embodiment a distributed computing graph represents processes executing in the distributed computing system in order to carry out the activity and this graph is available to entities in the distributed computing system. For example, a user interface at an entity in the distributed computing system enables a user to view a local representation of the distributed computing graph and to control the activity using that local representation which maps dynamically to and from the underlying distributed computing graph. In examples, the local representation of the distributed computing graph enables live control of the activity without the need for compilation. In examples the distributed computing graph is shared through the distributed computing system using peer-to-peer distribution or using a replication mechanism.
