VULFI - An LLVM based Fault Injection Framework

Download this project as a .zip file Download this project as a tar.gz file


VULFI is an open-source instruction-level fault injection framework developed using LLVM compiler infrastructure. VULFI performs fault injection at LLVM's intermediate representation (IR) level. It currently supports C, C++, ISPC, OpenCL, and MPI-C languages. Note that to target an OpenCL program for fault injection using VULFI, the program should be compiled using Intel's OpenCL Compiler. Conceptually, VULFI can target any high level language which can be compiled to LLVM's intermediate representation. It is our intention to keep VULFI up-to-date supporting the latest LLVM development branch while also maintaining reasonable support for older versions of LLVM.
