Parallel implementation of the raytracer, Data Structure & Algorithms

You are supposed to do the following:

  • Write a parallel implementation of the raytracer using pthreads.
  • Measure and compare the execution times for (i) the sequential version given to you, (ii) your parallel version on 1 cpu/thread, and (iii) your parallel version on 8 cpus/threads. Further, calculate the speedup of your parallel application on 8 cpus.
