This topic explains how to measure the efficiency of a parallel program and describes strategies for using parallel resources effectively.


After you complete this topic, you should be able to:

  • Explain how to measure the performance of parallel programs
  • Compare Amdahl's Law and Gustafson's Law and explain their implications
  • Explain how synchronization impacts program efficiency
  • Distinguish between weak and strong scaling

This topic assumes a basic understanding of serial (single-threaded) programming and familiarity with computer terminology.
