HPC Exercise 4: MPI Collective Communication, Parallel I/O, and Combining Patterns

Objectives

• Use the Data Decomposition. Master-Server, Parallel Loop, Message-Passing, Collective Communication, and Parallel I/O patterns to solve a problem.
• Use compiler optimization to speed up a sequential computation.
• Use parallelism to speed up a sequential computation.
• Analyze a computation to determine its performance bottlenecks.
• Compute the speedup and efficiency of a parallel computation.
