Cores are used for computer memory. Originally solid iron, some cores now are laminated or powdered iron. A current trend in systems design is to place multiple computing cores on a single chip to improve performance. These are called multicore or multiprocessing systems.

• Discuss multicore programming. At a minimum, include the following:
  • A brief explanation of what multicore programming is
  • The relationship between multithreaded programming and multicore programming
  • The difference between parallelism and concurrency
  • Types of parallelism
  • Challenges in programming for multicore systems
