SY40-Project

The goal of this program is to simulate the behaviour of a jam factory. We split the problem in 4 separated elements which must be synchronized.

• The small jar injector
• The big jar injector
• The valve
• The clock

We need to make the same exercise using two separate sets of tools

• Processus and semaphores
• Threads and monitors For both we can write a solution (pseudo-code) considering we have a function P(int i) which is called by a processus/threads waiting for another processus/threads to call V(int i).

Pseudo-code

Jar Function	Valve Function	Clock Function	Jar_2 Function
Start While True Then Insert_Jar() V(1) P(0) Remove_Jar() V(3) P(3) End While End	Start While True Then P(1) Open_Valve() V(2) P(2) Close_Valve() V(0) End While End	Start While True Then P(2) Sleep(30) V(2) End While End	Start While True Then P(3) Insert_Jar() For i from 0 to 2 V(1) P(0) Remove_Jar() V(3) End While End

Usage

 Usage ./main
  -t              , run the demo using threads and monitors. (Default use semaphores and processus)
  -v, --verbose   , explain what is being done
  -g1 [VALUE]     , number of small jar to produce (Default 1)
  -g2 [VALUE]     , number of big jar to produce (Default 1)
  -h, --help      , display this help and exit
      --version   , output version information and exit
