For this quiz, be able to:

-- Read and write parallel programs that use the OpenMP shared memory
model, when reminded of the syntax for the commands.

-- Read and write parallel SPMD programs that use message passing commands
      Send,
      Receive,
      Reduce,
      AllReduce,
      Broadcast,
      Scatter,
      Gather/Allgather,
      Barrier
when given the syntax for the commands.

-- Identify and avoid the main pitfalls of parallel computing:
deadlock, sequential execution, race conditions.

-- Measure speedup and efficiency.

-- Use Amdahl's law to bound parallel execution time.

-- Distinguish between shared memory computing and distributed
memory computing and identify advantages/disadvantages.

-- Distinguish between SIMD, MIMD, and SPMD programming and
identify advantages/disadvantages.

-- Explain what GPUs are, why they are good computational 
devices, and why they can be difficult to use effectively.

-- Read parallel programs that use Cuda or OpenCL, given
syntax definitions for calling upon the GPU.
