Abstract
Described techniques and tools help model checking scale to large programs while reducing missed errors. In particular, described techniques and tools help reduce the state space of concurrent programs without depending on cycle detection and without scheduling execution of postponed threads at all cycles. For example, described techniques and tools use a type of partial-order reduction called transaction-based reduction to reduce program state space. Analysis is performed at commit points to determine whether to schedule delayed threads.
