Modern architectures become more susceptible to transient errors with the scale down of circuits. This makes reliability an increasingly critical concern in computer systems. In general, there is a tradeoff between system reliability and performance of multithreaded applications running on multicore architectures. In this paper, the authors conduct a performance-reliability analysis for different parallel versions of three data-intensive applications including FFT, Jacobi Kernel, and water simulation. They measure the performance of these programs by counting execution clock cycles, while the system reliability is measured by Thread Vulnerability Factor (TVF) which is a recently proposed metric.
