Synthesized answer
The author proposes a method for deriving explicit synchronization commands needed for multiprocess programs executing on modern multiprocessors [1]. This method is based on a correctness proof of the algorithm [1].
The passages do not provide specific evidence in the form of experimental results or examples of such proofs. The author's evidence is limited to the proposal of this method.

Title: How to Make a Correct Multiprocess Program Execute Correctly on a Multiprocessor by Leslie Lamport Categories: Computer programs Pages: 10 Snippet: Abstract: "A multiprocess program executing on a modern multiprocessor must issue explicit commands to synchronize memory accesses. A method is proposed for deriving the necessary commands from a correctness proof of the algorithm."
