| Summary: | Abstract: "Traditionally, distributed recovery schemes have been designed for systems consisting of multiple recovery units. Each recovery unit (RU) resides on a single processor and it can fail and recover as a whole. This report introduces the 'distributed recovery unit (DRU)' abstraction as an approach for design of 'hybrid' and 'adaptive' recovery schemes for distributed systems. The distributed system is viewed as a collection of DRUs, each DRU consisting of one or more RUs. This report presents a new recovery scheme based on the DRU abstraction. The proposed approach combines coordinated checkpointing with independent checkpointing and optimistic message logging to obtain a recovery scheme that can effectively trade the overhead during failure-free operation with the overhead during recovery." |
