Hybrid Message Pessimistic Logging. Improving current pessimistic message logging protocols. |
Abstract | ||
|---|---|---|
With the growing scale of HPC applications, there has been an increase in the number of interruptions as a consequence of hardware failures. The remarkable decrease of Mean Time Between Failures (MTBF) in current systems encourages the research of suitable fault tolerance solutions. Message logging combined with uncoordinated checkpoint compose a scalable rollback-recovery solution. However, message logging techniques are usually responsible for most of the overhead during failure-free executions. Taking this into consideration, this paper proposes the Hybrid Message Pessimistic Logging (HMPL) which focuses on combining the fast recovery feature of pessimistic receiver-based message logging with the low failure-free overhead introduced by pessimistic sender-based message logging. The HMPL manages messages using a distributed controller and storage to avoid harming systems scalability. Experiments show that the HMPL is able to reduce overhead by 34% during failure-free executions and 20% in faulty executions when compared with a pessimistic receiver-based message logging. A low overhead Hybrid Message Pessimistic Logging (HMPL) protocol is presented.The HMPL focus on providing fast recovery with low failure-free overhead.A temporal buffer in senders is used to reduce penalties in critical paths.A detailed comparison of the HMPL with a classic receiver-based logging is presented.Overhead reductions up to 34% in failure-free and 20% in faulty executions. |
