Abstract : Traditionally, tightly coupled multiprocessors allow data sharing between multiple caches by keeping cached copies of memory blocks coherent with respect to shared memory. This is difficult to achieve in a fault tolerant environment due to the need to save global checkpoints in shared memory from where consistent cache states can be recovered after a failure. The architecture presented in this report solves this problem by encapsulating the memory modifications done by a process into an atomic transaction. Caches record dependencies between the transactions associated with processes modifying the same memory blocks. Dependent transactions may then be atomically committed. Such an operation requires a cache coherence protocol responsible for recording process dependencies as well as keeping coherent cached copies of blocks and a shared stable transactional memory owing to which all memory updates are atomic to allow recovery after a processor failure. This report also presents potential performance for this architecture the data for which was obtained through simulation.
