Parity: Protecting Shared Memory
Tuesday November 23, 2004

In recent years, fault-tolerance has become an increasingly
important feature of shared-memory multiprocessor systems.
Researchers have investigated various mechanisms using some
level of redundancy to protect a single processor core, interconnection
network, or memory system. The distributed parity mechanism
was recently proposed to avoid a non-ECC recoverable data loss
in shared-memory multiprocessor systems.
In this talk, I will present our distributed parity proposal.
Our shared-memory protection mechanism minimizes the performance
overheads of past distributed parity solutions.
