Abstract: A computing device configured to identify portions of a computing job that are assigned to the computing device, if any, based on identification information of the computing job and identifiers of a list of computing devices present in a computing network to process the computing job. The portions are identified by the computing device independent of other computing devices in the computing network. For example, the identification information of the computing job can be mapped by the computing device to a set of identifiers of computing devices based on a predetermined computing function. Each of the identifiers corresponds to a predetermined portion of the computing job. If one of identifiers corresponds to the identifier of the computing device, the computer device performs the predetermined portion of the computing job associated with the mapped identifier.

Abstract: A computing device configured with a rule engine to apply a set of predetermined rules to conditions relevant to changes of presence data of computers in a computing network forming a computing entity in which data stored in the computing entity is distributed among the computers for redundancy and data recovery. In response to the absence of a computer previously present in the computing entity, the rules cause the computing device to communicate with one or more of the computers to perform data recovery and store data with redundancy with the absent computer. In response to the addition of a new computer in the computing entity, the rules cause the computing device to communicate with one or more of the computers to redistribute data across the computing entity to use the storage capacity offered by the new computer.

Abstract: A computing system having a plurality of computers connected via a computer network to form a computing entity. Each of the computers operates substantially independent of others. Each of the computers is configured to interrogate network infrastructure of the computer network to determine the identity of the computing entity when the computer is connected to the computer network and thus join the computing entity by announcing its presence in the computing entity. Each of the computers is configured to determine an identifier of the computer in the computing entity based on the connectivity configuration in the network infrastructure and assume a role to perform a portion of operations of a computing request directed to the computing entity over the computer network, based on the presence data of the computers in the entity.
