Coordinated multi-mode allocation and runtime switching for systems with dynamic fault-tolerance requirements

摘要

A method for dynamically re-allocating controller functions based on minimizing utilization. A lookup table is generated based on functions and mode of operations. Each entry in the lookup table includes a number of executions required for a respective function in a respective mode of operation. Functions for execution to the controllers are assigned based on the number of executions for a function of an entry of a respective mode of operation. A utilization rate is determined for each controller in each mode of operation. Utilization rates of the various modes of operation are compared for each of the controllers. Matching utilization rates are identified between controllers of different modes of operations. A multi-mode re-allocation of function execution in the controller is coordinated by switching a set of pre-allocated functions between different controllers within a respective mode of operation to reduce the utilization rate of at least one controller.
