Disclaimer : This article is technically in adept for reading. So there is a high probability that u will understand it. A very short post.
The last 3 days were spent reading a subject called parallel processing for the end sems and I was wondering all the time why was I reading it ???? how would it help me ???? I wrote the exam today and i realised that this subject is a must read for people who are toppers like me .hence this article is dedicated to all those people. Reading into the night till 3 and waking up at 6 for the exam at 8.30 can be the worst experience .
The exam scenario (parallel processing exam)
Unlike my earlier adventures I intended to score full marks in this one by leaving one whole unit and sparing the teacher some work. I reached the college on time , seated myself and tried to keep myself busy by observing others. Soon I had the question paper in my hand and I prayed to god to hand me an easy paper and help me score full marks.
Sab upar waale aur teacher ke haath me hota hai(everything rests in the hand of god and teacher).
As I read the question paper , I soon realised my dream of scoring full marks was soon to be realised. I started from the last question a habit I have had since my 10th std and slowly made my way up. In 1.5 hrs I had finished 2 units and was really happy. It was then when god decided to have some fun with me. I couldn’t remember how to draw reservation table from state diagram. I got tensed and nothing seemed to help me. As I looked around hopelessly seeking help , I realised everyone was busy with their own papers . It is then I decided to employ my strength and tried using legilimency on everyone around me only to realise everyone else had mastered the art of occlumency . Damn Harry Potter!!!!
With no other option I decided to use my last option available to me. Till now I was running on uniprocessor . So I decided to turn on my other processors which are connected in parallel . but damn Amdahl was right . No matter how many processors, I wasn’t able to find the way for conversion . I decided to delve into my caches but to cache coherence problem i was left helpless . It was then I realised why I was reading parallel processor . Before I tell u what I did , let me explain u some basic things,
Read-miss : What u didn’t read came in the paper. In such a case u can go for a write hit or a write miss
Read-hit : Whatever u read came in the paper. (very high probability for me)
Write hit : Whatever u write is bang on target. Has two cases
In case of a read hit , u get a write hit
In case of a read miss u can go for a write but the chances of being write hit are very high for people like me. (u better not try)
Write –miss : Whatever u write is shite.
In case of a read miss and u go for a write , this is a very high probability for people like u to have a write –miss .
Snoopy protocol : U try snooping on other’s papers hoping to catch some answers. People like me don’t do such ridiculous things .
Gossip protocol: U try to speak to others in hushed voices for some answers . People like me don’t do things like these either.
With the help of the snoopy protocol and the gossip protocol ( I regret this. My first time), I manage to draw the reservation table and my dreams are back on track . I soon complete the paper and get out realising whatever I read for the exam didn’t go in waste . All the people are advised to use these methods if and only if they are experienced enough.
P.S: In the best interests of the teacher’s and my branch mates health , I decided to leave one unit in the exam. It was high time i allowed others to hog the limelight .
