Problem: How can a problem be solved with more than one computer?

• Parallelism in the form of threads
• Scheduled onto processors by the JVM
• Creating threads
• Joining threads

Note: Threads may start in the second half of the previous week.

• Simple thread creation
• Thread states demonstration
• Matrix multiply
  Demonstrates speed up extremely well.

Problem: How do concurrently executing threads interact?

• Scheduling
• sleep and yield methods
• Nondeterminism
• Synchronization via polling

• Thread drawing an animation
• Two threads printing their names to the screen
  Demonstrates non-determinism and scheduling.
• Logic Simulator with polling
