The shrinking processor feature size, lower threshold voltage and increasing clock frequency make modern processors highly vulnerable to transient faults. Architectural Vulnerability Factor (AVF) reflects the possibility that a transient fault eventually causes a visible error in the program output, and it indicates a system's susceptibility to transient(More)
— In recent years, modern graphics processing units have been widely adopted in high performance computing areas to solve large scale computation problems. The leading GPU manufacturers Nvidia and ATI have introduced series of products to the market. While sharing many similar design concepts, GPUs from these two manufacturers differ in several aspects on(More)
In recent years, single-ISA heterogeneous chip multipro-cessors (CMP) consisting of big high-performance cores and small power-saving cores on the same die have been proposed for the exploration of high energy-efficiency. On such heterogeneous platforms, an appropriate runtime scheduling policy lies at the heart of program executions to benefit from the(More)
