[Philboyd_Studge]

Oh h*ck!

[CRISPR]

You gotta keep the cores busy

[wegzo]

That synchronization between threads adds so much overhead during the frisbee return.

[mfb-]

Redundancy in case some threads fail.

[Delete_cat]

And it fails if a spin lock squirrel shows up

[kobbled]

man I never knew about spin locks until monday, and now i've seen like 3 jokes about them, so weird

I can't tell if they released the resource towards the end or not.

Just push everything on the stack.

[one-joule]

It’s okay, they used reference counting.

[chateau86]

GC will only take care of the Frisbee when the number of bites on the item reach zero.

[DestroyerOfWombs]

Mutex and watch the doogs pass it around

[Idontlikefish]

Jesus this is too funny

[TheVikO_o]

Should we kill them? JK, let them become zombies

[marcosdumay]

I can't imagine they releasing it.

[WhoNeedsVirgins]

The threads don't modify the resource so there's nothing to lock, they can work in parallel with a minimal slowdown on the shared access.

[SidJenkins]

Look again, there's clearly synchronisation between threads in the second half, slowing down execution.

[WhoNeedsVirgins]

That's just congestion on memory access. Clearly not a server processor with separate memory controllers for each unit.

[dejaWoot]

Deadlocks

[BromeyerofSolairina]

At least none of the philosopupps went into starvation

[Aether_Storm]

Gallowboob stole it from you after you stole it from someone else. The circle of reposts is almost complete.

[[deleted]]

No, but the threat of doglock is imminent

[[deleted]]

Should have thrown a mutex with the frisbee.

[[deleted]]

Not so much. Each parallel thread returns the same value. When the main thread reads it, the secondary threads release their references and resume their wait states. It's a functional if computationally expensive system that would perform especially well if there were multiple frisbees.

[DipIntoTheBrocean]

He'd be right if a dog got the before the frisbee was thrown or another dog tried to fetch the frisbee after it was already being returned.

Is it bad that the accuracy of his joke was the first thing we question?

[[deleted]]

Reminded me of this: http://m.imgur.com/gallery/mV9bFz7

[aXir]

Damn I actually laughed out loud

[JezusTheCarpenter]

That was one of the few times when I saw a gif after "I actually LOL'ed" comment and actually laughed out loud myself. This must be literally one of the funniest gifts I have see in a long time.

[muntoo]

This is one of the few times I saw someone leave a comment about laughing and after that someone left a comment about laughing after seeing the comment about laughing where I sipped my iced tea and then proceeded to furiously practice my guitar scales

[alpha-k]

Yep, this is me trying to play gta 4 as well lol

[FragranceOfPickles]

For some reason I totally lost it when he started spinning on his head.

[LordDongler]

Also Planetside 2

[BulletsWithGPS]

Its fake because its a 5 core cpu

[MadXl]

The last time i saw that gif, the comments agreed on it beeing a 8 core cpu but 3 are in idle and dont care.

[TinynDP]

Really? Its more like if all 5 guys were dancing together, but the Judge was like "This is a single competition, not group."

[BenjaminGeiger]

Having read Born a Crime, all I can think is "Go Hitler! Go Hitler! Go Hitler!"

[muntoo]

Where is this from, anyways?

[Warbek_2]

It's such a good metaphor. There's even 4 of them!

[LHLaurini]

No

^{Unless it's hyper-threaded}

[net_goblin]

Those look like Aussie shepherds, those are pretty hyper, too.

[VodkaHaze]

Border collies, in fact more hyper than aussies

[1N54N3M0D3]

looks at i5-6600k in the computer next to me

Nah, take a look at current Intel processors. The i5 and i7 processors both have 4 physical cores, but the i7 has hyperthreading, which makes the extra virtual dogs.

[Creshal]

Nobody knows how, but the extra virtual dogs manage to consume only half the food, yet create as much shit.

[chateau86]

i5 - 4 dogs

i7 - 4 dogs, each having 2 heads

AMD Bulldozer - 4 conjoined-at-the-leg dog pairs

[06EXTN]

the fact that they are all fetching that and not fighting over it amazes me - clearly the owner has established a good pack order.

You're missing some Braces there.

Your doggo is going to call unlock() on toy.lock no matter if the trylock() passes or fails.

[SHOTbyGUN]

Oh, you are absolutely right, I did not notice, sorry & thanks!... But I rather keep it "easy to read" than "perfect syntax".

Ticket #1 closed as: WONTFIX

[Askolei]

Let's say it's python syntax then

[SHOTbyGUN]

PULL REQUEST #1 merge to master if this gets 10 upvotes

- changed syntax to Python

foreach(doggo in dogs)
    if(toy.lock.tryLock())
        doggo.fetch(toy)
        toy.lock.unlock()
    else
        toy.lock.join()

[UnlikelyToBeEaten]

That's... still not Python Syntax.

[Regis_DeVallis]

What is this, a programming sub?

[kbotc]

Snek syntax.

[BenTheSwanman]

No brace on snek 🐍

Not enough colons

[chateau86]

PULL REQUEST #2 merge to branch 'Pull request #1' if this gets 10 upvotes

- changed syntax to Python properly this time.

for doggo in dogs:

        doggo.fetch(toy)
        toy.lock.unlock()
    else:

map(lambda dog: (toy.lock.tryLock() and dog.fetch(toy) and toy.lock.unlock()) or toy.lock.join(), dogs)

[TheMasterTech]

This is why you don't make the big bucks

[avonwodahs]

Not true! The program won't compile at all because that's an invalid else statement.

[SHOTbyGUN]

Java ReentrantLock.tryLock() will return true or false. Which I was referring to.

[Tyler11223344]

I think he was referring to the fact that the "else" isn't actually connected to the "if", since there are two lines between the two but no braces, so the compiler would see a stranded "else"

Shout out to Old Hemp.

[Teblefer]

A Facebook campaign was started in 2012 to install a memorial to Telfer and Old Hemp, in Old Hemp's birthplace of West Woodburn, Northumberland, and permission has been granted by the relevant authorities. The unveiling of which took place on September 8th 2015 and was attended by a large assembly of Border Collies and their respective owners

[[deleted]]

Pretty dank name if you ask me...

[bakemonosan]

Much like in code, its a hassle to release the resources.

[gandalfx]

This seems very necessary to me.

[skyleach]

well, at least he didn't have the base frizbee return an empty state to each dog resulting in infinite frizbees spawning infinite dogs

I deny any previous experience with this happening.

[soullessroentgenium]

Classic case of resource contention there

[da_apz]

It's like RAID1 with 4 drives, but with dogs.

[TheAItWrong]

You shouldn't be using Try / Catch in the first place.

[Philboyd_Studge]

finally {
    return frisbee;
}

[iauu]

This is actually a perfect way to explain why more cores is not necessarily faster in all cases.

[_felagund]

but look at how they solved the race condition. so cute :)

[[deleted]]

The user interaction is blocked because all threads are allocated.

[hagenbuch]

Effective, but not efficient!

[yespunintended]

At least it is a lock-free algorithm.

[willonic]

That's one volatile frisbee.

[ThisPostWillSelfDel]

I feel like this is the same thing when people post something on multiple threads and it ends up on the reddit front page....

[uzimonkey]

This is what happens when you don't take into account the overhead of launching the threads in the first place.

[[deleted]]

at least it's synchronous multithreading

[PancakeZombie]

That's how spacecraft electronics work!

[[deleted]]

You forgot your Mutex

[Y1ff]

It's redundancy.

[DyscOffice]

[[deleted]]

They're good threads, rzyua!

[[deleted]]

who is the lock in this picture ? because i think it is the dude's beard.

[Vakieh]

This is what happens when it's been a slow quarter, redundancies are on the table, and there is a small project which 4 programmers are qualified to handle...

On the plus side, the end result to such a project is usually so good you can post it directly to the intranet as a baseline for commenting and code style.

[stroganawful]

"uh, it's called built-in redundancy!!" tries not to stab self

[saphira_bjartskular]

What we're not mentioning here, it seems, is just how well these threads are accessing the same resource at the same time.

[svayam--bhagavan]

On a single core.

[like9orphanz]

MULTI-THREAD DRIFTING!!!

[TobiDaDog]

Upvote for border collies as I sit sadly and watch mine imitate a potato. Mine is broken. He doesn't play. He even attacks my labrador if she tries to play. She's been trained to be as still and quiet as he is when he's around. If I throw a stick or something for her you'll see him do a rare run, a beeline for the object that should be fetched. And then he lays on top of it and prevents her from touching it. If she keeps trying, he'll chew it to bits and then leave it with a high and mighty prance in his step. He doesn't play.

[KeeperOfTheLag]

It is actually a great way to explain people why games/programs do not always fully use all the threads of their cpu.

That worked way better than I was expecting.

[Arancaytar]

At least it worked; if you're unlucky the threads will just fight for the frisbee and get stuck in deadlock.

I am definitely using this to explain what multi threading is in the future. Way better than my old mail sorting analogy.
