摘要： 检查点机制是高性能并行计算系统中重要的容错手段，随着系统规模的增大，并行检查点的可扩展性受文件访问的制约。针对大规模并行计算系统的多级文件系统结构，提出了cache式并行检查点技术。它将全局同步并行检查点转化为局部文件操作，并利用多处理器结构进行乱序流水线式写回调度，将检查点的写回时机合理分布，从而有效地隐藏了检查点的写回开销，保证了并行检查点文件访问的高性能和高可扩展性。

Abstract: Checkpointing is a typical technique for fault tolerance, whereas its scalability is limited by the overhead of file access. According to the multi level file system architecture, the cache-style parallel checkpointing was introduced,which translates global coordinated checkpointing into local file operation by out of-order pipelining of checkpoint flushing opportunity. The overhead of writcback is hidden effectively to increase the performance and the scalability of parallel checkpointing.
Key words: Cachcstylc checkpointing, Parallel computing, Multi-level file system, Multi-processor, Out-of-order pipeline
