For boundedness and deadlocks... - one of

the most important properties .. you can use petri nets

and reason about place invariants equations that you

extract from the resolution of the following equation:

Transpose(vector) * Incidence matrix = 0

and find your vectors...on wich you wil base your reasonning...

you can do the same - place invariants equations... -

and reason about lock and lock-free algorithms...

And you can use also graph reduction techniques...

As an example , suppose that you resolve

your equation Transpose(vector) * Incidence matrix = 0

and find the following equations

P,Q,S,R are all the places in the system...

2 * M(P) M(Q) + M(S) is constant

and

M(P) + M + M(S) is too equal to a constant

Note also that vector f * M0 (initial marking) = 0

So, it follows - from the equations - that since

M(P) + M + M(S) = C1 , it means that

M(P) <= C1 and M <= C1 and M(S) <= C1

and, from the second invariant equation , we have

that M(Q) <= C2 , this IMPLY that the system is

structuraly bounded.

That's the same thing for deadlocks , you reason

about invariants equations to proove that there is

no deadlock in the system...

Now, if you follow good patterns , that's also good...

And what's a good pattern ?

It's like a THEOREM that we apply in programming...

As an example:

Suppose that or IF - we have two threads that want to aquire

crtitical sections, IF the first thread try to aquire critical section A and

after that critical section B, and the second threads try to

aquire B and A THEN you can have a deadlock in this system.

you see ? it's look like this: IF predicates are meet THEN somethings ...

Now suppose there is many criticals sections... and the first

thread try to aquire A ,B ,C ,D,E,F,G and second thread try to

aquire A,G,C,D,E,F,B that's also a problem ... you can

easily notice it by APPLYING the theorems that we call

'good patterns'.

You see why good patterns - that looks like theorems -

are also very powerfull ?

That's what we call a good pattern - it's like a theorem ,

and it looks like this: IF predicates are meet THEN somethings ...

There is also good patterns - like theorems - to follow for false

sharing etc.

Do you understand why I and others follow also good patterns

- that look like theorems - ?

Think about it...

Take care...

Sincerely,

Amine Moulay Ramdane.
