Fault state recovery using predefined configurations, including: 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, wherein each of the plurality of predefined failure states corresponds to a respective configuration of a plurality of configurations; and applying the respective configuration corresponding to the identified failure state, wherein applying the respective configuration comprises 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.

Fault state recovery using predefined configurations

Shared memory access in a distributed system, including: receiving a memory access request associated with a time value; determining, based on the time value, an entry in a translation lookaside buffer (TLB); and determining, based on the entry, whether to allow the memory access request.

Shared memory access in a distributed system

Fault state transitions in an autonomous vehicle may include determining that a first node of a plurality of nodes has failed; determining, in response to the first node failing, a failure state; determining, based on the failure state, a configuration for the plurality of nodes excluding the first node; and applying the configuration.

Fault state transitions in an autonomous vehicle

Shared memory access in a distributed system, including: determining, in response to a memory access request, based on a time value, an entry in an access permissions table by: determining, based on a modulo of the time value and a number of entries in the access permissions table, a table index; determining, based on the table index, the entry; and determining, based on the entry, whether to allow the memory access request.

Timed memory access

Timed memory access, including: determining, in response to a memory access request, based on a time value, an entry in an access permissions table; and determining, based on the entry, whether to allow the memory access request that can include determining, based on a modulo of the time value and a number of entries in the access permissions table, a table index and determining, based on the table index, the entry.
