Fault-Tolerant Linux
FT-Linux pioneers full-software stack fault-tolerance on a single SMP machine based on the Linux software ecosystem, demonstrating -- through a proof-of-concept -- that monolithic operating systems such as Linux can be made fault resilient.
FT-Linux enables Linux to tolerate transient and permanent hardware failures. FT-Linux is built on top of the replicated-kernel version of Linux, Popcorn Linux, and aims to provide fault tolerance along the whole software stack, from the OS kernel to applications. FT-Linux targets SMP machines in which there are multiple core/processor domains as well as memory controllers (and eventually I/O controllers), with the presumption that each of them may fail independently. Two main categories of faults are considered: a) permanent failures such as fail-stop errors and b) transient errors such as bit-flops in main memory.
