Final Exam Topics

The final exam will be cumulative, but will focus on material since the midterm.

Parallel Concepts

• Be able to define the following:
  • Non-determinism.
  • Race conditions.
  • Thread safety.
• Be able to calculate speedup and efficiency.
• Be able to apply Amdahl's Law.

Pthreads

• Understand usage of mutexes, semaphores, conditions and read-write locks.
• Understand cache issues.

OpenMP

• Understand differences between Pthreads and OpenMP.
• Use OpenMP directives to parallelize short programs.
• Understand OpenMP scheduling and reductions.

MPI

• Be able to compare shared memory vs. message passing paradigms.
• Be able to parallelize short programs with MPI.
• Understand collective MPI communication.

CUDA
