Asserting and checking determinism for multithreaded programs
Jacob S. Burnim, Koushik Sen · 2009
The trend towards processors with more and more parallel cores is increasing the need for software that can take advantage of parallelism. The most widespread method for writing parallel software is to use explicit threads. Writing correct multithreaded programs, however, has proven to be quite challenging in practice. The key difficulty is non-determinism. The threads of a parallel application may be interleaved non-deterministically during execution. In a buggy program, non-deterministic scheduling will lead to non-deterministic results - some interleavings will produce the correct result while others will not.
