Application Fault Injector

Application Fault Injector (AFI) is a simple com- puter program for testing the fault tolerance of other programs. AFI is a library of subroutines designed to inject faults into memory, data structures, and registers. The library is modular, can easily be extended, and can easily be ported to different computer hardware architectures. AFI is not designed to run fault-injection campaigns on complete application programs: instead, it is designed to test fault-tolerant algorithms, subroutines, and data structures. AFI is easy to use. The application programmer has complete control of fault injection.
