C952 Computer Architecture Chapter 7
Multiprocessor - correct answer ✔✔A computer system with at least two processors.
This computer is in contrast to a uniprocessor, which has one, and is increasingly
hard to find today.
Task-level parallelism or process-level parallelism: - correct answer ✔✔Utilizing
multiple processors by running independent programs simultaneously.
Parallel processing program - correct answer ✔✔A single program that runs on
multiple processors simultaneously.
Cluster - correct answer ✔✔A set of computers connected over a local area network
that function as a single large multiprocessor
Multicore microprocessor - correct answer ✔✔A microprocessor containing multiple
processors ("cores") in a single integrated circuit. Virtually all microprocessors today
in desktops and servers are multicore.
Shared memory multiprocessor (SMP - correct answer ✔✔A parallel processor with a
single physical address space.
To benefit from a multiprocessor, an application must be concurrent. - correct
answer ✔✔False:
Task-level parallelism can help sequential applications and sequential applications
can be made to run on parallel hardware, although it is more challenging.
Strong scaling - correct answer ✔✔Speed-up achieved on a multiprocessor without
increasing the size of the problem.
Weak scaling - correct answer ✔✔Speed-up achieved on a multiprocessor while
increasing the size of the problem proportionally to the increase in the number of
processors.
