Example text

Since shared objects encapsulate their state, those fragments are always disjoint. The fragment corresponding to a shared object X is called a local state of X at pi . Consider any implementation history E of a shared object X, and let Y be any shared object whose events are in E (including X). Again, because of encapsulation, and since processes are deterministic, it is possible to unambiguously determine the local state of Y , at every process, at every point in E. 18 2. SHARED MEMORY SYSTEMS Let E and E be some implementation histories of any shared object X, and let pi be any process.

Write(4); tryC → C1 ; Consider another transaction T2 that is executed by some process pi concurrently with T1 . 3. PRECLUDING INCONSISTENT VIEWS 39 1. If pi tries to compute the value of 1/(y − x), then a “divide by zero” exception will be thrown, which can crash the process executing the transaction or even the entire application. 2. read ; while vx = vy do array[vx ] ← 0; vx ← vx + 1; (where vx , vy , and array are variables local to pi ), and indeed pi reads vx = vy = 4, then unexpected memory locations could be overwritten, not to mention that the loop would need to span the entire value domain.

Where each αk → vk , k = 1, 2, . , is one of the following: • write(vk ) → ok, where vk ∈ D, or • read → vk , and either (a) the latest write operation preceding read → vk is write(vk ), or (b) no write operation precedes read → vk and vk = v0 (the initial value of x). For instance, the following sequences are some elements of the sequential specification of a t-variable with the initial value 0 (we omit the ok return values of write operations): read → 0 , write(1), read → 1 , write(1), write(2), read → 2, write(3), read → 3 .
