Abstract	Software distributed shared memory (DSM) improves the programmability of message-passing machines and workstation clusters by providing a shared memory abstract (i.e., a coherent global address space) to programmers. As in any distributed system, however; the probability of software DSM failures increases as the system size grows. This paper presents a new efficient logging protocol for adaptive software DSM (ADSM), called adaptive logging (AL). It is suitable for both coordinated and independent checkpointing since it speeds up the recovery process and eliminates the unbounded rollback problem associated with independent checkpointing. By leveraging the existing coherence data maintained by ADSM, our AL protocol adapts to log only unrecoverable data (which cannot be recreated or retrieved after a failure) necessary for correct recovery, reducing both the number of messages logged and the amount of logged data. We have performed experiments on a cluster of eight Sun Ultra-5 workstations, comparing our AL protocol against the previous message logging (ML) protocol by implementing both protocols in TreadMarks-based ADSM. The experimental results show that our AL protocol consistently outperforms the ML protocol: Our protocol increases the execution time slightly by 2% to 10% during failure-free execution, while the ML protocol lengthens the execution time by many folds due to its larger log size and higher number of messages logged. Our AL-based recovery also outperforms ML-based recovery by 9% to 17% under parallel application examined.
