Fault state recovery using predefined configurations

An apparatus comprising one or more processors and memory storing instructions that, when executed, cause the one or more processors to perform steps comprising:

• determining that a first node of a plurality of nodes has failed;
• identifying, based on the first node failing, a failure state from a plurality of predefined failure states each corresponding to a different combination of one or more failed nodes;
• applying the respective configuration corresponding to the identified failure state, by at least one of updating one or more memory mapping tables based on the respective configuration or copying data from memory locations used based on a previous configuration to memory locations indicated in the respective configuration;
• and
• determining, during a code compilation, the plurality of predefined failure states.

A computer program product comprising a non-transitory computer readable medium and computer program instructions disposed upon the non-transitory computer readable medium, the computer program instructions that, when executed, cause a computer system of an autonomous vehicle to carry out the steps of:

• determining that a first node of a plurality of nodes has failed;
• identifying, based on the first node failing, a failure state from a plurality of predefined failure states each corresponding to a different combination of one or more failed nodes;
• applying the respective configuration corresponding to the identified failure state, by at least one of updating one or more memory mapping tables based on the respective configuration or copying data from memory locations used based on a previous configuration to memory locations indicated in the respective configuration;
• and
• determining, during a code compilation, the plurality of predefined failure states.
