Webster's 1913 Dictionary
\Par"al*lel*ism\, n. [Gr. ?, fr. ? to place side by
side, or parallel: cf. F. parall['e]lisme.]
1. The quality or state of being parallel.

2. Resemblance; correspondence; similarity.

         A close parallelism of thought and incident. --T.

3. Similarity of construction or meaning of clauses placed
   side by side, especially clauses expressing the same
   sentiment with slight modifications, as is common in
   Hebrew poetry; e. g.:

         At her feet he bowed, he fell: Where he bowed, there
         he fell down dead.                    --Judg. v. 27.

Computing Dictionary

1. parallel processing.

2. The maximum number of independent subtasks in a given task at a given point in its execution. E.g. in computing the expression

        (a + b) *

(c + d) the expressions a, b, c and d can all be calculated in parallel giving a degree of parallelism of (at least) four. Once they have been evaluated then the expressions a + b and c + d can be calculated as two independent parallel processes.

The bernstein condition states that processes P and Q can be executed in parallel (or in either sequential order) only if:

(i) there is no overlap between the inputs of P and the outputs of Q and vice versa and

(ii) there is no overlap between the outputs of P, the outputs of Q and the inputs of any other task.

If process P outputs value v which process Q reads then P must be executed before Q. If both processes write to some variable then its final value will depend on their execution order so they cannot be executed in parallel if any other process depends on that variable's value.

 Definition: a condition in which homoplastic similarities are found in related species that did not exist in the common ancestor. However, the common ancestor provided initial commonalities that gave direction to the evolution of the similarities.
