Abstract
A method, apparatus, and program product checkpoint an application in a parallel computing system of the type that includes a plurality of hybrid nodes. Each hybrid node includes a host element and a plurality of accelerator elements. Each host element may include at least one multithreaded processor, and each accelerator element may include at least one multi-element processor. In a first hybrid node from among the plurality of hybrid nodes, checkpointing the application includes executing at least a portion of the application in the host element, configuring and executing at least one computation kernel in at least one accelerator element, and, in response to receiving a command to checkpoint the application, checkpointing the host element separately from the at least one accelerator element upon which the at least one computation kernel is executing.
