Synthesized answer
The provided passage discusses a method for deriving synchronization commands from a correctness proof of an algorithm to ensure multiprocess programs execute correctly on a multiprocessor [1]. It states that modern multiprocessors require explicit synchronization commands for memory accesses [1].
The passages do not contain information about what questions remain unanswered.

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."
