Description:
please see attachment


Write a program in C++ and Win32 API to simulate the function of snoopy caches.

Your program actually contains four files, each representing a process. Among the four processes, three of them perform the operation of cache controllers and the fourth one performs the operation of a memory controller. Win32 API socket message passing mechanism is used to simulate the operation of automatic detection of modified data in a cache.


>cpsc735p3m1 {this is the memory controller}
>cpsc735p3c1 {this is the first cache controller}
>cpsc735p3c2 {this is the second cache controller}
>cpsc735p3c3 {this is the third cache controller}
>s(a,3) {in m1 console}
>s(b,1) {in m1 console}
>w(a,4) {in c2 console}
>r(a) {in c3 console}
>w(a,5) {in c3 console}
>s(c,2) {in m1 console}
>r(c) {in c2 console}
>r(c) {in c1 console}
>s(d,6) {in m1 console}
>w(d,7) {in c2 console}
>w(c,8) {in c1 console}
>r(a) {in c2 console}
>p {in c1 console}
c = 8


>p {in c2 console}
a = 5
c = invalidated
d = 7
>p {in c3 console}
a = 5
>p {in m1 console}
a = 5
b = 1
c = 8
d = 7
>exit
>



Deliverables:

Pseudo code for r(v)
if the variableis in the cache then
if the variable is invalidated then{
the cache controler sends a message to the memory controler
the memory controler sends a variable to the cache controler
the cache controler update the varaibles in the cache
the cache controler validates the variable in the cache
}
else{
the cache controler sends a message to the memory controler
the memory controler sends a variable to the cache controler
the cache controler stores the value in the cache

}
psudeocode for w(v,i)
if the variableis in the cache then{
the cache controler update the varaibles in the cache
the cache controler sends a message to the memory controler
the memory controler updates the variable in memory
the cache controler sends a n invalidations message to all other cache controlers;
those cache controlers having a copy of the variable invaldate the variable
}
else{
the cache controler sends a message to the memory controler
the memory controler update the varaibles in the memory
the memory controler sends a variable to the cache controler
the cache controler stores the value in the cache
the cache controler sends a n invalidations message to all other cache controlers;
those cache controlers having a copy of the variable invaldate the variable
