Abstract

Program verification is a resource-hungry task. This paper looks at the problem of parallelizing SMT-based automated program verification, specifically bounded model-checking, so that it can be distributed and executed on a cluster of machines. We present an algorithm that dynamically unfolds the call graph of the program and frequently splits it to create sub-tasks that can be solved in parallel. The algorithm is adaptive, controlling the splitting rate according to available resources, and also leverages information from the SMT solver to split where most complexity lies in the search. We implemented our algorithm by modifying Corral , the verifier used by Microsoft’s Static Driver Verifier (SDV), and evaluate it on a series of hard SDV benchmarks.

分布式有界模型检查

程序验证是一项耗费资源的任务。本文着眼于并行化基于smt的自动程序验证问题，特别是有界模型检查，以便它可以分布并在机器集群上执行。我们提出了一种动态展开程序调用图的算法，并经常将其拆分以创建可并行解决的子任务。该算法具有自适应性，根据可用资源控制分割率，并利用SMT求解器的信息对搜索中最复杂的地方进行分割。我们通过修改Microsoft的静态驱动验证器(SDV)使用的验证器Corral来实现我们的算法，并在一系列硬SDV基准上对其进行评估。

期刊介绍： The focus of this journal is on formal methods for designing, implementing, and validating the correctness of hardware (VLSI) and software systems. The stimulus for starting a journal with this goal came from both academia and industry. In both areas, interest in the use of formal methods has increased rapidly during the past few years. The enormous cost and time required to validate new designs has led to the realization that more powerful techniques must be developed. A number of techniques and tools are currently being devised for improving the reliability, and robustness of complex hardware and software systems. While the boundary between the (sub)components of a system that are cast in hardware, firmware, or software continues to blur, the relevant design disciplines and formal methods are maturing rapidly. Consequently, an important (and useful) collection of commonly applicable formal methods are expected to emerge that will strongly influence future design environments and design methods.
