摘要： Methods, apparatus, and products are disclosed for error recovery during execution of an application on a parallel computer that includes a plurality of compute nodes. Such error recovery includes: storing, by the application during execution on the nodes, application restore data in a restore buffer at predetermined points during execution of the application, the restore data specifying an execution state of the application at one or more points during application execution; encountering, by at least one of the nodes executing the application, a recoverable error during application execution; determining, by the application, the nodes affected by the recoverable error; restarting, by each of the affected nodes, execution of the application; retrieving, by the restarted application executing on each of the affected nodes, the restore data from the restore buffer; and continuing, by each affected node, execution of the application with the execution state specified by the retrieved restore data.
