Question 1

5 classes of computers

Answer 1

Personal/Mobile
Desktop
Server
Clusters/Warehouse
IoT/Embedded

Question 2

Data-level parallelism (DLP)

Answer 2

application parallelism where many data items can be operated on at the same time

Question 3

Task-level parallelism (TLP)

Answer 3

application parallelism where tasks of work are created that can operate independently and in parallel

Question 4

Instruction-level parallelism

Answer 4

exploits DLP using ideas like pipelining and speculative execution

Question 5

Vector, GPU parallelism

Answer 5

exploits DLP by applying a single instruction to a collection of data in parallel

Question 6

Thread-level parallelism

Answer 6

exploits DLP or TLP in tightly coupled hardware model that allows for interaction between parallel threads

Question 7

Request-level parallelism

Answer 7

exploits parallelism among largely decoupled task

Question 8

Purpose of ISA

Answer 8

Programmer visible instruction set

Boundary between hardware and software

Question 9

Types of ISAs

Answer 9

Accumulator, Stack, General Purpose Registers

Question 10

What are operands?

Answer 10

Operands are registers or memory locations

2 types: General Purpose and Floating Point

Sizes: word (32 bits). half-word (16), byte (8)
