Fault tolerant control phd thesis proposal

Fault tolerant control phd thesis proposal Computer Engineering, North Carolina State


Overview

There’s growing concern that transient problems, brought on by cosmic sun rays along with other factors, will occur frequently later on high-performance processors, as designers push technology to the extreme limits. Existing fault-tolerant techniques are generally too pricey (system-level replication), too intrusive (gate-level replication), or too specific (e.g. ECC on memory). In 1999, we suggested a microarchitectural method of fault tolerance (AR-SMT), achieving broad coverage of transient problems with low performance overhead and couple of changes towards the underlying microarchitecture. We revisit this notion and explore different ways the microarchitecture might help reliability.

This project is continuing. For background, please stick to the Slipstream Project link around the primary research page.
