Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

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.

💡 Hint: Consider the tasks in terms of parallel versus sequential execution.

Question 2

True or False: concurrency issues in multicore processors are strictly related to hardware limitations.

  • True
  • False

💡 Hint: Think about what happens when multiple processes interact.

Challenge Problems

Push your limits with challenges.

Question 1

Analyze how Amdahl's Law affects a given software application with 70% parallelizable code. How much speedup can be expected with addition of cores?

💡 Hint: Remember the formula related to the fraction of non-parallelizable code.

Question 2

Design a thermal management plan for a hypothetical multicore CPU system to mitigate heat dissipation issues. What would be your key components?

💡 Hint: Consider both hardware and software solutions.
