High performance linpack benchmark: a fault tolerant implementation without checkpointing

  title={High performance linpack benchmark: a fault tolerant implementation without checkpointing},
  author={Teresa Davies and Christer Karlsson and Hui Liu and Chong Ding and Zizhong Chen},
The probability that a failure will occur before the end of the computation increases as the number of processors used in a high performance computing application increases. For long running applications using a large number of processors, it is essential that fault tolerance be used to prevent a total loss of all finished computations after a failure. While checkpointing has been very useful to tolerate failures for a long time, it often introduces a considerable overhead especially when… CONTINUE READING
