| Abstract(in English) | Cluster systems have been widely utilized especially in high performance computing because of its good cost performance. Fault tolerant techniques are needed for such cluster systems. Conventional checkpointing techniques assume common and constant failure-rate among nodes and during execution time. However, in practice, failure-rate is different among nodes and fluctuates during computation. We proposed a checkpointing method which is adaptive for such variations by focusing on the interval of checkpointing. In this paper, performance evaluation of our new checkpointing is presented. The result shows that our method reduces the overhead for both space and time variations of failure-rate. |
