Objectives:

1. Use High Performance Linpack and other common benchmarks to explore fundamental concepts in parallel computing:

   * Strong scaling & Amdahl’s law

   * Weak scaling & Gustafson's law

   * Theoretical performance & efficiency

   * “Memory wall” and arithmetic intensity

   * Bandwidth & latency

2. Gain practical experience with parallel computing software and tools:

   * MPI & OpenMP

   * BLAS libraries

   * Linux perf counters

3. Understand the impact of system and processor architecture on performance:

   * P-states

   * Hyperthreading

   * NUMA

   * SSE/FMA instructions

   * Processor cache hierarchy
