Passed but 44/80 on locking

General Considerations (maximum = 100): 90
Documentation (maximum = 70): 69
O-O Design (maximum = 30): 30
GUI (maximum = 40): 28
Locking (maximum = 80): 44
Data store (maximum = 40): 40
Network server (maximum = 40): 40
Total 341.

I believe the poor locking score is due to using a scheme that requires notifyAll and thus burns some CPU, I know some students have got full marks for that.

Hi Peter,

Congrats on passing

As an FYI, I'm pretty sure I know what the score is all about, and it's not notifyall. Now that you've passed, do you want send me your code?

Would you be willing to share with us, in a general way of course?

Congratulations Peter, I know I've looked at many of your posts here for tips, and it's good to know the person I was getting tips from passed!

Congratulations Peter!

Glad to see that you passed the test too. When I started out on my assignment, you had convinced me to go for the fat client model, so in that sense you have had a major influence on my own general design.

BTW, I am curious why you had the infamous 44/80 locking score. If possible, could you share Max's findings with the forum?

Frans.

Congrats Peter.

I don't know if I interpreted you correctly, but I have a colleague who used notifyAll() and got 80/80 for locking.

I'm aware that some people have got 80/80 using the simple Map and notifyAll method for locking, it appears that everybody who got 44/80 also used that method.

Max says that's not the cause, but I've gone over everything else and I'm mystified by that score.

Hi, Peter. First off, congratulations on your passing the exam! If I may ask, could you also send your code to my email agolovin@hotmail.com? I used the notifyALL() and a simple Map, and was fortunate to avoid 44/80, so I think there is something else which may cause this deducation.

It would be very interesting to take a look at the actual code.
