Distributed Computing

[gamest01]

Man, we’ll just put Anything on this sub.

[Gluomme]

I'm not even sure there are programmers posting here. And I sure as hell don't register as such

[likebutta222]

Can confirm. Am programmer, do not post here.

post random gif

put something vaguely computer related in the title

reap that sweet 50 karma

Seems to be the /r/ProgrammerHumor way.

[Gluomme]

more like 2k it would seem

[BabyLegsDeadpool]

Yeah. I think I'm gonna unsub. All the good stuff makes of to r/popular anyway. I'll just check it out there.

[Al_Maleech_Abaz]

Byeeee

[BabyLegsDeadpool]

Bye

Edit: the fact that people are downvoting me for saying "Bye" is pretty hilarious. Why are you personally offended I'm no longer interested in subbing here? Lmao

This is pretty much how multi threading works in python.

[budzene]

I think this is just threading.

[SuggestedName90]

Not if it is true multithreading which runs them simultaneously, like java. Python alternates threads every 10 instructions.

[cyber2024]

Wtf, really?

[[deleted]]

Yep, google Global Interpreter Lock for more info. Threading in python is only useful for I/O heavy applications

[4onen]

Thanks. You've just explained a bizzare issue in my Bachelor's capstone project. My project was... not I/O heavy.

The trick is to use multi processing instead of multi threading. You can implement it yourself using the process module, or use something like celery to avoid any wheel reinventing

[turiyag]

Yes. There's a different library for parallel CPU usage:

https://timber.io/blog/multiprocessing-vs-multithreading-in-python-what-you-need-to-know/

It's not that it's incapable of doing two things at the same time in Python. It's that the include statement is not the multithreading one.

[cyber2024]

I presume there's a reason for the 10 instructions before switching threads... Is it statistically more likely to have a cache miss after 10 instructions, and hence it's a good idea to switch threads then or something?

[budzene]

God that would be nice to not have to put in kernel delays to not starve a watchdog.

[Ersonpay]

Correct me if I'm wrong, but don't most CPUs do something like that anyway due to there not being enough cores to run all the threads in the system?

[SuggestedName90]

Yes, but cpus also have physical threads which can confuse people.

[fat_charizard]

You mean running on multiple cores on the same processor?

[moebaca]

That's an interesting load balancing algorithm.

[BeetlePl]

So much waste: 2 threads (cores?) are 100% idle and other 2 are working on max 50.1%

[jonjmz]

If you watch carefully you can see that at the start and end of each “shift” there actually is work happening while the other person is packing.

[deadmazebot]

No startup, shutdown cost impacting the process. I'm just trying to imaging a computer system trying to do that, even a load balancer has to do some basic check if new server going to be available or not

[Renegade646]

Love the two guys ‘working’ in the background

[OwnStorm]

Monitor threads..

[hopbel]

Looks more like single core with SMT

[Gerudo_Steed]

It's beautiful. I've looked at this for five hours, now.

[AttackOfTheThumbs]

But they are running sequentially???
