A method for executing a comprehensive real-time computer application including an application software including a description of functions on a distributed real-time computer system including sensors, actuators, computing nodes, and distributor units having access to a global time. The application software including a number of real-time software components (RTSWCs). When executed, the RTSWCs exchange information by time-triggered messages. Each RTSWC is allocated a time-triggered virtual machine TTVM, wherein, during a service interval SI, an operating system running on a computing node provides a TTVM realized on the computing node with protected access to the network resources and memory resources of the computing node assigned to the TTVM, and wherein, during the SI, a defined computing power for processing the RTSWCs running in the TTVM is allocated to the TTVM by the operating system of the computing node such that the RTSWCs provide a result before the end of the SI.
