Abstract: In some examples, a distributed computer system includes a plurality of computer nodes, where the plurality of computer nodes include respective programs to cooperate to perform a workload. A first computer node includes a communication proxy between the program of the first computer node and a communication library that supports communications between the program of the first computer node and the programs of other computer nodes of the plurality of computer nodes, and a fault management service to monitor a health of the other computer nodes, and in response to a detection of a fault of a second computer node of the plurality of computer nodes, relaunch the communication proxy. The relaunched communication proxy selects, from a plurality of states, a common state to which the programs are to roll back.
