Please explain step-by-step how to solve these kinds of questions
For each of the following five statements, state if the statement is true or false. If you claim that the statement is false, answer shortly why the statement is false (2 sentences). You do not need to give a motivation if the statement is true. (5 points) i. Weak scaling means that the experiment was performed on few computers with Weak processing powei. ii. SIMD can work for applications that can make use of data-level parallelism iii. A processor that supports VLIW (Very Long Instruction Word) is designed to utilize instruction level parallelism (ILP). iv. Register renaming is a way to solve hazards due to out-of-order execution. v. Hyper-threading is Intel's approach for scheduling software threads efficiently within the operating systemExplanation / Answer
1) Weak scaling means that the experiment was performed on few computers with weak processing power .
FALSE
Weak scaling is the process of keeong work per worker fixed and addition of more processors or workers . The efficiency is calculated as,
( t1 / tN ) * 100%
2) SIMD can work for application that can make use of data level parallelism.
TRUE .
It is the class of parallel computers it can make use of data level parallelism but not in concurrency .
3) A processor that supports VLIW is designed to utilize ILP .
TRUE
VLIW is the instruction set architecture it is designed to utilize ILP .
4) Register renaming is a way to solve hazards due to out of order execution.
TRUE
The register renaming removes the false data dependencies which are caused because of out of order execution.
5) Hyper threading is intel approach for scheduling software threads efficiently within the operating system.
TRUE
The Hyper threading approach makes sure of the utilization of multiple threads efficiently in an OS .
