并行作业容错自动调度环境设计
Design of a Fault-Tolerant Environment for the Automatic Scheduling of Parallel Tasks
摘要
Abstract
Large-scale scientific and engineering computing needs to realize unprecedented complex numerical simulation and process huge data,and it is necessary to design a fault-tolerant environment for auto-reloading the failed parallel tasks. Based on parallel jobs and the system-provided checkpoint/restart function, we design a user-level,fault-tolerant environment for job auto-scheduling, including the auto-perception of fault-tolerant parallel program scheduing, auto-reloading, and data integrity ensuring. The experimental results demonstrate that the design of the fault-tolerant environment achieves the de-sign requirements of parallel program scheduling which requires auto-reloading the failed applications and ensures the cor-rectness and completeness of the checkpoint data.关键词
