3. Introduction to Pintos
 Simple OS for the 80x86 architecture
 It was developed at Standford University
 We use bochs, qemu Simulators to run Pintos
 Provided implementation supports kernel threads,
user programs and file system
 In the projects, strengthen support for these +
implement support for virtual memory

4. Objectives
 Extend the functionality of a minimally functional
thread system
 Implement
- Alarm Clock
- Priority Scheduling
- Advanced Scheduler

5. Quick Review: Thread Scheduling
Thread A ___________ ________
Thread B ______ _____ _____
Kernel __ __ __ __

6. H/W & S/W Required
H/W req :
Any 80x86 CPU, monitor, keyboard.
S/W req :
Bochs and QEMU Simulators.
Vmware, Turbo C++.
CVS (Concurrent Versions System)
For managing and merging code written by the team members.

7. Development Environment
ap2.cs.vt.edu containing
repository
import
checkout
& update
commit
Development machine
in McB124
contains “working directory”
Other useful CVS commands
- diff
- add
- remove
- update
ssh transport

8. Pintos Thread System

9. Conclusion
 Build infrastructure and thread
package to allow running user
programs.
 To provide a function to be run in this
context as an argument to
thread_create().
