Abstract: A method of operating programs on a computer cluster comprising non-virtual real hardware resources with variable configurations and virtual resources. Each cluster resource has a configuration description and a type, the type comprising a unique type identification and descriptions of operations which can be performed by the cluster resource of the each type. Each program is operable to request usage of the cluster resource specifying the type and the configuration description; and requesting a modification of the variable configuration of the non-virtual real hardware resource with the variable configuration. Execution of each program requires the dedicated execution environment on the computer cluster. The generation of each dedicated execution environment requires one or more dedicated virtual resources and one or more dedicated non-virtual real hardware resources with the variable configurations. Each dedicated resource has an execution environment specific type and an execution environment specific configuration description. In response to a modification request a real resource is reserved with a record being generated. On completion of the program the created record is used to roll back the configuration and release the reserved resource.
