Process Synchronisation

Question

What is the significance of infinite loop that is written in every example of process synchronisation?

What would happen if there wasn't any infinite loop?

Comments

are you talking about busy waiting?

---

infinite loop :  deadlock state in which  process never do progress

busy waiting :  process go in busy state for limited amount of time or we can say definite amount of time.

starvation :  somewhere in between busy wait and infinite loop, process doesn't go to deadlock but we not know  how much time it will take in that process.

while(True) or while(1) {

Logic

}

What's the need of infinite loop here?

(e.g. while demonstration of strict alteration, etc)

Answer 1

$to\ check\ synchronization\ between\ processes\ have\ to\ consider\ few\ points$

• mutual exclusion
• bounded wait
• progress

$\ to\ check\ this\ have\ to\ execute\ code\ number\ of\ times\ but\ few\ programs\ give\ correct\ result\\$

$certain\ amount\ of\ times.\ In\ terms\ of\ mathematics, it\ is\ similar\ to\ finding\ a\ counter\ example.\\$

$to\ use\ infinite\ loop\ we\ try\ to\ find\ more\ accurate\ code\ for\ concurrency\\$

$It\ would\ need\ a\ significant\ amount\ more\ in-depth\ understanding\ of\ the\ situation\ to\\$

$determine\ why\ an\ infinite\ loop\ was\ selected\ in\ a\ certain\ situation.$
