The Bounded Buffer Problem

[@venkateshpatil7109]

Thanks

[@cloudjumper725]

To make the code a bit clearer, I would suggest renaming "empty" semaphore to "free_slots" and "full" semaphore to "taken_slots". Makes it easier to understand what this code does and to memorize the fact that wait() performs a decrement operation while signal() increments the value. Othervise quality lesson, as always. Thanks.

our teacher recommends ur channel as she herself learns here lmaooo

[@EnigmaAI-88]

😂😂😂

[@yashaswininag3783]

Because it is recommended in VTU syllabus.. You people are unbelievable.. No gratitude towards anyone

[@ChitragaarAshokaraju]

Same

[@Playtimetales65]

​Why show gratitude we are spending lakhs and they don't even know how to explain anything properly. So we end up referring channels on KZbin​@@yashaswininag3783

[@ChandanKSwain]

Explanation level is outstanding. It makes too easy to grasp...

[@maanyamuthamma3577]

You deserve an award for doing this 🎉🎉

[@aquadap219]

i watched the past 6 videos of process synchronization and theyre amazing videos thank you!

[@rupambiswas953]

Thanks for saving my semester exam 🙏🙏💙💙

[@mamathaav4627]

Your teaching method is really good.keep on going sir.😊

[@ganesh_hulagur]

Bruh your videos are really help full Plzz do upload remaining topics like *The reader -writer problem *The Dining philosophers problems #monitors etc🙏

[@adelgado0723]

I think this is a version of the reader-writer problem

[@jameysiddiqui6910]

This is basic discussion which is good, please can you explain the scenario where producer and consumer can work in paralell.

[@kayakMike1000]

I don't think you really need semaphores and mutexes for this. The producer and consumer could be operating in parallel through some threading mechanism. Assuming there's only one consumer and one producer, we could have a read pointer "chase" the "writer" pointer. the consumer thread isn't allowed to change anything other than it's own read pointer, and we also assume that if the previous element in the buffer has already been consumed. If the consumer measures the read and write pointers to be identical, then the consumer doesn't use that value untill the write pointer is different. If the read and write pointers are different, the consumer consumes the data, then increments its read pointer to point at the next element in the buffer. Now the producer has a write pointer that will increment if the next element in the buffer is not where the read pointer is pointing to. The idea here is the read pointer always chases the write pointer, you could even do this with a ring buffer... With this scheme, the buffer is "empty" when everything has been read, and the read pointer and write pointer point at the same thing. The buffer is full if the write pointer can't advance because the next pointer is where the read pointer actually is..

[@j4jeev678]

Just make 2 thread functions for each producer and consumer and then run both the threads and join it with main thread

u are a life saver . thank u so much sir

[@TheEkimjeet]

great presentation and slides! love the content

[@advithgowda620]

Brooo u r a life changer 😘

[@zuhal6900]

That's what i've been looking for!!!! just perfect!!

[@DrJALAGHARI]

A very good way of explanation. Keep it up.

[@user-ytuser]

thanks you explained an important topic in a easy manner

[@codeWithNoComments]

Binary Semaphore and Mutex are different. At 4:29 they are being used interchangeably. To preserve a critical section, semaphore must not be used. It should've been an actual Mutex.

[@snehasharma3041]

Amazing explanation 🥹

[@darshil-oh2le]

Awesome explaination ✌✌

[@adelgado0723]

Thank you for the excellent content!

[@EnigmaAI-88]

Great videos 💯

[@baraaabuasal5626]

i am an electrical engineer i dont know anything about cs but i saw the video, i clicked, i am now studying this problem with you and i understand everything. thank you but may i ask, what is this programming language?

[@pranavvenkata475]

the language used for the implementation of the solution is C

[@lakshyakanjani2313]

Thapu

[@putrescentvermin]

This was basically my OS project.

[@PythonisLove]

great content as always

[@ith3r7]

Well explained !!

[@ayahamad5931]

Thanks sir❤❤

[@tasnimsart3430]

Thanks so much

[@arvinhipolito157]

One of the best explanation. Thank you very much

[@liorlivyatan]

Why performing signal(mutex) before signal(full)? If a context switch happens in between, won't it cause problems?

[@kayakMike1000]

Why are they using mutexes and semaphores in the first place?

[@-shultz]

yeah , empty should be called before and then the lock must be released .

[@kenzakhelkhal7931]

Thank u so much it was very helpful appreciate ur efforts

[@thegamingsoul831]

Please call the mutex Locks by their name. mutex made that kinda confusing. 15:21

[@Rachinter]

Thank u

[@mrymzrzr4741]

Thank you was really helpful

[@sarthakpal5795]

How are we keeping track of the index in which the producer and consumer will insert or consume item?

[@aryansharma9933]

Thank you!

[@kayakMike1000]

I don't think you really need mutex or semaphores if you only have one producer for one consumer...

[@sanathkumarshenoy9955]

Nice one

Thxxx sirr

Fantastic

can you please upload the remaining topics like deadlocks :)

hi neso academy, a copyright thing is happening in our college. our college lecuturer is using your content by taking screen shots and using it to teach our classes. please raise a compliant and remove him from our college as fast as possible thanks in advance!

[@farahmohamed2104]

[@marcustam4387]

I wonder if semaphores can solve this problem

[@siddharthbhagat7637]

bro whats the value of mutex when locked and release

[@FarmanOfficial777]

this is called teaching....

[@pranavmuthige427]

Bhai Tu bhagwaan hai bhagwaan!!!

[@modemharikumar9232]

1st comment good lecture

[@johndoe3092]

Too many semaphores ! Can we do with just 1 ?

[@michaelcenzoprano8173]

i agree, you should only need a mutex lock. You can just maintain a count of elements in the buffer.

[@brahamaggarwal1800]

The thing is when you are dealing with multiple processes that are sharing data then simple if-else statements fail to synchronize our processes that's why it is necessary to use these many semaphores here.

[@adityamishrasc2579]

🙏🙏🙏

[@sricharan8575]

how semaphores solve bounded waiting since u said test.and.set.lock cant solve bounded waiting..coz new process may enter critica.sec while old one was preempted so called the unlucky process?????

[@kswethakumari412]

I haven't listened anything before

[@hombdr.pathakkshetri8893]

wawwwaaaaa

[@satioOeinas]

i dont think this is the correct implementation

[@NireekshaKulali]

Is this a false information??

[@satioOeinas]

@@NireekshaKulalinot necessarily false, but I think it’s incorrect
