Question 1.
What does Amdahl's Law state about performance improvement?
Show hintHide hint
Consider the percentage of tasks that cannot be parallelized.
Question 2.
Name two common concurrency issues that can arise in multicore systems.
Show hintHide hint
Think about what happens when multiple threads access shared data.
3Question 3.
What does Amdahl's Law imply about achieving performance improvements with multicore architectures?
- Performance can always be perfectly improved.
- The speedup is limited by the sequential portion of tasks.
- No speedup can be achieved regardless of cores.
Show hintHide hint
Consider the tasks in terms of parallel versus sequential execution.
4Question 4.
True or False: concurrency issues in multicore processors are strictly related to hardware limitations.
- True
- False
Show hintHide hint
Think about what happens when multiple processes interact.
Question 5.
Analyze how Amdahl's Law affects a given software application with 70% parallelizable code. How much speedup can be expected with addition of cores?
Show hintHide hint
Remember the formula related to the fraction of non-parallelizable code.
Question 6.
Design a thermal management plan for a hypothetical multicore CPU system to mitigate heat dissipation issues. What would be your key components?
Show hintHide hint
Consider both hardware and software solutions.
