Various technological developments in the microprocessor world make modern computing
systems more vulnerable to soft errors than in the past, and consequently fault tolerance …

In order to allow user-level applications tolerate transient hardware faults, we developed
Romain, an operating system service that transparently replicates unmodified binary …

Operating systems (OS) manage computer hardware resources and provide services to the
user's applications. For reliable execution the OS depends on error free hardware. The …

As voltages decrease, soft errors are expected to become an increasing problem in
maintaining program correctness. Unfortunately, previous mechanisms to improve processor …

Software-based active replication is expensive in terms of performance overhead.
Multithreading can help improve performance; however, thread scheduling is a source of …

Soft errors are an important challenge in contemporary microprocessors. Modern processors
have caches and large memory arrays protected by parity or error detection and correction …

The system reliability becomes a critical concern in modern architectures with the scale
down of circuits. To deal with soft errors, the replication of system resources has been used …

Ever since transistor-based computers were invented in the 1960s, it is common that these
systems suffer from hardware errors. One particular error is a transient hardware error which …

Soft errors are an important challenge in contemporary microprocessors. Modern processors
have caches and large memory arrays protected by parity or error detection and correction …

This paper provides a model and an analytical study of replication as a technique to cope
with silent errors, as well as a mixture of both silent and fail-stop errors on large-scale …
