Shared Hash Tables in Parallel Model Checking

AbstractIn light of recent shift towards shared-memory systems in parallel explicit model checking, we explore relative advantages and disadvantages of shared versus private hash tables. Since usage of shared state storage allows for techniques unavailable in distributed memory, these are evaluated, both theoretically and practically, in a prototype implementation. Experimental data is presented to assess practical utility of those techniques, compared to static partitioning of state space, more traditional in distributed memory algorithms

Model Checking C++ with Exceptions

We present an extension of the DIVINE software model checker tosupport programs with exception handling. The extension consists of two parts, a language-neutral implementation of the LLVM exception-handling instructions, and an adaptation of the C++ runtime for the DIVINE/LLVM exception model. This constitutes an important step towards support of both the full C++ specification and towards verification of real-world C++ programs using a software model checker. Additionally, we show how these extensions can be used to elegantly implement other features with non-local control transfer, most importantly the longjmp function in C

Abstract PDMC 2007 Preliminary Version Shared Hash Tables in Parallel Model Checking 1

In light of recent shift towards shared-memory systems in parallel explicit model checking, we explore relative advantages and disadvantages of shared versus private hash tables. Since usage of shared state storage allows for techniques unavailable in distributed memory, these are evaluated, both theoretically and practically, in a prototype implementation. Experimental data is presented to assess practical utility of those techniques, compared to static partitioning of state space, more traditional in distributed memory algorithms.
