We present VeyMont: a deductive verification tool that aims to make reasoning about functional correctness and deadlock freedom of parallel programs (relatively complex) as easy as that of sequential programs (relatively simple). The novelty of VeyMont is that it “inverts the workflow”: it supports a new method to parallelise verified programs, in contrast to existing methods to verify parallel programs. Inspired by methods for distributed systems, VeyMont targets coarse-grained parallelism among threads (i.e., whole-program parallelisation) instead of fine-grained parallelism among tasks (e.g., loop parallelisation).
