Question

• Can Petersons solution for controlling access to
  critical sections be extended to more than two
  concurrent activities?
• What are the essential elements of a solution?

3
Requirements Controlling Access to a Critical
Section

• Symmetrical among n computations
• No assumption about relative speeds
• A stoppage outside critical section does not lead
  to potential blocking of others
• No starvation i.e. no combination of timings
  that could cause a computation to wait forever to
  enter its critical section

Virtual Machines Linux Kernel

• Requirement for CS-502 programming projects
• to be able to build, modify, and install a Linux
  kernel with root password
• SUSE Linux 9.3
• How many people have this environment set up
  already?

5
Options / Alternatives

• VMware Server, accessed via VMware client
• Requires ability to install client
• VMware Workstation on your personal computer at
  home or office
• VMware Player running previously created virtual
  machine
• Macintosh on Intel platform
• Parallels install SUSE Linux 9.3 directly
• Boot Camp install VMware xxx on Windows
  partition
• An other computer on which you can install SUSE
  Linux 9.3 directly
