摘要
Abstract
An automatic fault-tolerance method based on job checkpoint/restart in resource management systems is pro-posed The key technologies are presented, including the separation of job checkpoint and task checkpoint, management of checkpoint image files, and automatic job restart.Automatic job checkpoint/restart with BLCR is implemented in SLURM and the challenges are discussed. Analysis and experiments show that the checkpoint and restart works correctly, and the time to complete large-scale jobs is reduced effectively.关键词
