Abstract
A vehicle electrical architecture includes a first vehicle control module node including a first remote direct memory access (RDMA) capable network interface card and a mutex client, and a second vehicle control module node including a second RDMA capable network interface card, a mutex server, and a memory, with an Ethernet link in communication between the first and second RDMA capable network interface cards. The first vehicle control module node is configured to receive a write request for a specified memory region of the second vehicle control module node, communicate with the mutex server of the second vehicle control module node, via the mutex client, to request a mutex lock associated with the specified memory region, and in response to a notification of the mutex lock being obtained, execute an RDMA write operation to the specified memory region.
