• Course History

– An Operating Systems course, coded as CENG312 for juniors, had been

taught with “Windows APIs” and multi-threaded applications and IPC

implementations in accordance with the books by Silbershatz, A., Galvin,

P.A., Gagne, G.; “Operating System Concepts”, and by Nutt, G.,

“Operating System Projects Using Windows NT” for the past three years

in Izmir Institute of Technology.

• WAP Workshop – a small history...

– Early in February 2007, Microsoft Turkey provided WAP for the first time for us

to discover the new opportunity.

– Did meet Dr. Retik and Dr. Probert in Microsoft MEA Academic Days

2007,Tunisia.

– After attending to their WAP workshop, decided to have one in Turkey too.

– Then held a workshop on WAP in our department on September 15th & 16th of

2007 with great contributions of Dr. Retik and Dr. Probert of whom both from

Microsoft, Redmond, USA.

• Workshop on WAP, Windows Kernel Source and Internals: Sept. 15-16 2007, İzmir Institute of Technology, Turkey.

Workshop description:Windows Academic Program Workshop provides information and practical hands-on knowledge of the content, access to the Windows kernel source code, curriculum materials and a project environment for teaching and researching operating system principles. Instructors are Dave Probert (Kernel Architect, Windows Core Operating Systems Division, Redmond) and Arkady Retik (Windows Academic Program Manager, Source Asset Management, Redmond)

• Workshop on WAP, Windows Kernel Source and Internals: Sept. 15-16 2007, İzmir Institute of Technology, Turkey

Workshop objectives:Introduce faculty members to the Windows Academic Program (WAP) materials, Provide rudimentary hands-on experience accessing the Curriculum Resource Kit (CRK), building the Windows Research Kernel (WRK), and ProjectOZ, and Share ideas on how to successfully use these for lectures and projects/labs.

• After the WAP workshop

– Decided to utilize these WAP tools in our undergrad course “Ceng313-

Operating Systems” in a more efficient way.

– Thus, upgraded the course curriculum with the WAP tools and decided

to utilize the materials in the directory “Curriculum Resource Kit Units”

and to use the book named “Microsoft Windows Internals, 4th Edition,

Microsoft Press, 2004” by Russinovich & Solomon.

• Implementation

The Course Schedule

• The course books

– Silbershatz, A., Galvin, P.A., Gagne, G.; Operating System

Concepts, 6th Ed., John Wiley & Sons, USA, 2001.

– Russinovich, M. E., Solomon, D.A.; Microsoft Windows

Internals, 4th Edition, Microsoft Press, 2004.

– Nutt, G.J.; Operating Systems A Modern Perspective, 2nd

Ed., Addison Wesley, 2000.

• Lab books & other references– Nutt, G.J.; Operating System Projects Using Windows NT,

Department of Computer Science University of Colorado,

1999.

– http://www.sysinternals.com :Tools used in labs and

experiments

– http://msdn.microsoft.com: Online resource for information

on APIs required during work on assignments.

• Grading– This semester the course was taken by 58 juniors for

fourteen weeks of both course and lab. The grading was done as below:

[ 20% of midterm + 30% of final exam + 50% of the average of the lab assignments & a lab exam ]

• The overall performance– 12 juniors were unsuccessful out of 58 and they are to repeat the

course. So the overall success of the course is 79%.– The distribution of the grades for the whole class

• Our findings

1. Generally our students were far more attracted to the course and its labs

this year which clearly shows that they did easily grasp the concepts of

the course and thus they enjoyed implementing the exercises and

assignments in the laboratory that all conducted under WAP. At the end

of the year, the course was scrutinized by us and by our students in one

last session and we found out that our students were a lot more happier

since they were able to create and to implement OS codes easily.

• Our findings (continued)

2. The freshmen did have some difficulties with the book “Microsoft Windows

Internals, 4th Edition” for the book actually requires a prerequisite

knowledge of OS theory. For that reason we feel that it is more suitable as

a secondary book for the course along with the other classical books on the

subject. However, this peculiarity makes the book perfect for grad level

studies. So we recommend that the book be utilized as a secondary for

undergrads while can be first for grad level studies and for code

development projects.


3. The system-internals tools are quite useful to understand and to monitor the

objects and to clarify some troublesome concepts of operating systems

such as the difference between process and thread, performance

monitoring, scheduling and of memory usage. Since these tools add a

dimension of visualization to the hard-to-grasp theoretical concepts of OS

we highly recommend it for the undergrad education.


4. Unfortunately the time didn’t permit us to fully utilize “virtual PC” and

“Project Oz” tools and thus they will be utilized in the next fall term.

However; we feel that these tools are more appropriate for the

miscellaneous code development projects and for the graduate level

courses.

Thank you so much for your time!
