A computer system (CS) for executing a customer function (CUS) comprising an automotive customer function, wherein the customer function (CUS) generates customer function output data (OUT-DAT), based on which a machine comprising an automobile, is controlled, wherein the computer system (CS) comprises:
- one or more processing cores, “core” (Core 1, Core 2, Core 3),
- wherein the customer function (CUS) comprises applications (APP1, APP2, APP3), wherein each application (APP1, APP2, APP3) of the customer function (CUS) comprises a multitude of different tasks (T1.1-T1.3, T2.1-T2.9, T3.1-T3.4), wherein during the execution of an application (APP1, APP2, APP3) one or more tasks of said application are executed,
- wherein said applications (APP1, APP2, APP3) are executed in form of a computation chain (CHA) one after the other in a defined sequence,
- wherein a computation chain (CHA) receives customer function input data (IN-DAT) at its start and generates customer function output data (OUT-DAT), which are provided at the end of the execution of the computation chain (CHA),
- and wherein during execution of the customer function (CUS) said computation chain (CHA) is executed once or several times, wherein
- the computer system (CS) provides containers (CON1, CON2, CON3), wherein the computer system (CS) is configured to activate and de-activate said containers, so that a container is active or inactive,
- wherein all tasks of the applications are assigned to containers (CON1, CON2, CON3), and wherein all tasks of each specific application are assigned to exactly one specific container,
- wherein in a timeframe, during which a container is active, one or more cores of the computer system are exclusively reserved for the execution of the tasks of the application of said container, and
- wherein the computer system (CS) is configured such that when a container is inactive, the tasks of said container cannot be executed on the computer system,
- wherein the computer system is configured to executed the containers (CON1, CON2, CON3) according to the sequence of the applications (APP1, APP2, APP3), so that a container is activated before his immediately following container, and wherein a container and its immediately following container of a computation chain are not allowed to overlap in time,
- and wherein for each container a task sequencer is provided, wherein said task sequencer is activated when its container is activated, and wherein the task sequencer of a container decides (“task-sequencer-decision”),
- which of the tasks of the application of the container have to be executed,
- the sequence of tasks to be executed, and
- for each task, which has to be executed, the core or cores which the container provided, on which core or cores the task has to be executed,
- and wherein the computer system is configured to executed the tasks of each container according to said task-sequencer-decision of the task sequencer of each of the containers.
