Abstract

A fault tolerant processing environment wherein multiple processors are configured as worker nodes and redundant nodes, with a failed worker node replaced programmatically by a manager node. Each of the processing nodes may include a processor and memory associated with the processor and communicate with other processing nodes using a network. A manager node creates a message passing interface (MPI) communication group having worker nodes and redundant nodes, instructs the worker nodes to perform lockstep processing of tasks for an application, and monitors execution of the tasks. If a node fails, the manager node creates a replacement worker node from one of the redundant processing nodes and creates a new communications group. It then instructs those nodes in the new communications group to resume processing based on the application state and checkpoint backup data.
