| 发明名称 | Checkpointing for a hybrid computing node | ||
| 摘要 | According to an aspect, a method for checkpointing in a hybrid computing node includes executing a task in a processing accelerator of the hybrid computing node. A checkpoint is created in a local memory of the processing accelerator. The checkpoint includes state data to restart execution of the task in the processing accelerator upon a restart operation. Execution of the task is resumed in the processing accelerator after creating the checkpoint. The state data of the checkpoint are transferred from the processing accelerator to a main processor of the hybrid computing node while the processing accelerator is executing the task. | ||

| 主权项 | 1. A method for checkpointing in a hybrid computing node, the method comprising: executing a task in a processing accelerator of the hybrid computing node; creating a checkpoint in a local memory of the processing accelerator, the checkpoint comprising state data to restart execution of the task in the processing accelerator upon a restart operation; resuming execution of the task in the processing accelerator after creating the checkpoint; and transferring the state data of the checkpoint from the processing accelerator to a main processor of the hybrid computing node while the processing accelerator is executing the task, wherein the transferring is performed asynchronously on a lower bandwidth interface with the main processor, and a higher speed interface is used to create the checkpoint. | ||
