benchmark's Introduction

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
