Exercises and review questions

• Questions on current lecture's material
  1. Write code to estimate pi using numerical integration, and parallelize it using OpenMP.

• Questions on next lecture's material
  1. How will you use the schedule clauses to perform cyclic distribution of loop indices to the threads (that is, thread t gets iterations t, t+P, t+2P, ... with P threads)?
