The specialized vocabulary used in this book is defined here. In some cases, where existing terminology is ambiguous, we have given all meanings but note which meaning we primarily use in this book.
absolute speedup: Speedup in which the best parallel solution to a problem is compared to the best serial solution to the same problem, even if they use different algorithms. See relative speedup.
access controls: Any mechanism to regulate access to something, but for parallel programs this term generally applies to shared memory. The term is sometimes extended to I/O devices as well. For parallel programming, the objective is generally to provide deterministic results by preventing an object from being modified by multiple tasks ...
