Louis writes a multithreaded program, which produces an incorrect answer some of the time, but always completes. He suspects a race condition. Which of the following are strategies that can reduce, and with luck eliminate, race conditions in Louis’s program?

A. Separate a multithreaded program into multiple single-threaded programs, run each thread in its own address space, and share data between them via a communication link that uses send and receive.

B. Apply the one-writer rule.

C. Ensure that for each shared variable v, it is protected by some lock lv.

D. Ensure that all locks are acquired in the same order.
