In order to deploy a tightly-coupled multiprocessor (TCMP) in the commercial world, the TCMP must be fault tolerant. Researchers have designed various checkpointing algorithms to implement fault tolerance in a TCMP. To date, these algorithms fall into 2 principal classes, where processors can be checkpoint dependent on each other. We introduce a new apparatus and algorithm that represents a 3rd class of checkpointing scheme. Our algorithm is distributed recoverable shared memory with logs (DRSM-L) and is the first of its kind for TCMPs. DRSM-L has the desirable property that a processor can establish a checkpoint or roll back to the last checkpoint in a manner that is independent of any other processor. In this paper, we describe DRSM-L and present results indicating its performance.
