9.1 Synchronization
Note:
instruction sequences regardless of how multiple threads alternately executed, the program must work properly
-> multithreaded program is uncertain and non-reproducible features
-> not been designed, very difficult to debug
uncertainty require parallel program correctness
-> to think clearly questions the behavior of the program design is clear
-> Do not rush to start writing code, having problems re-commissioning
9.2 some of the concepts
(1) Race condition race condition
system deficiencies: the result depends on the order or events executed concurrently: uncertainty, not reproducible
avoid race: Let instructions is not interrupted
9.3 concepts
To be added complete
