CSCI 3150 - C program optimization

In this tutorial, we are going to learn some optimization methods for C programs, as outlined as follows:

• The performance of programs are measured by cache misses and TLB misses, which can be checked by using perf

• Some concrete examples showing the optimization tricks are given:

  • Sorting and Hack

  • Loop unrolling

  • Sequential access and random access

Try to play around with them! Hope you can enjoy this lab!
