    • A method, system, and computer usable program product for energy-efficient soft error failure detection and masking are provided in the illustrative embodiments. A soft error is injected to occur during execution of a set of instructions. If an output of the execution of the set of instructions is incorrect, a record is made of the instruction that was affected by the injected soft error and led to the incorrect result. This identified instruction is designated as vulnerable to the soft error. Several soft errors are injected with different input data sets over several executions of the same set of instructions, and a probability of each instruction in the instruction set is computed, the probability of an instruction accounting for the vulnerability of the execution of the instruction sets to errors that affect the instruction. A report including several probabilities of instruction vulnerabilities is produced.
    • 在说明性实施例中提供了用于节能软错误故障检测和屏蔽的方法,系统和计算机可用程序产品。 注意在执行一组指令期间发生软错误。 如果执行该指令集的输出不正确,则记录受注入软错误影响的指令,并导致不正确的结果。 该识别的指令被指定为易受软错误的影响。 在同一组指令的几次执行中,通过不同的输入数据集注入了几个软错误,并且计算指令集中的每个指令的概率,指令执行指令集的脆弱性的概率 影响指令的错误。 产生了一个报告,其中包括几个指令漏洞的概率。
