Week 09 Notes for CS 3750 -- Fall 2002

• Take Roll.
  
  
• Look at the upcoming schedule and homework.
  
  
• Announcements
  
  
  • I posted a ThreadInfo directory and a Prog01 directory with your first concurrent programming assignment
    
    
  • Lets look at some homework solutions.
    
    
  • We are reading chapter #13 (I/O Systems) and some of chapter #14 (Mass-Storage Structure)
    
    
  • Lecture topics are deadlock, memory management, and virtual memory
    
    
  • 
    
    
• We need to talk about the programming assignment -- look at the "HiHo" code and the passFood shell code -- see the difference between the output you get with and without synchronization.
  
  
• You need to study the solutions in the text that use semaphores to solve synchronization prolems: the producer-consumer problem, the readers-writers problem, and the dining philosophers problem.
  
  
• I need to go over part of the worked-out example of application of the bankers algorithm and finish up with discussion of deadlock detection before going on to lecture on memory managment.
