Operating system purpose on some website is vague and not some canonical truth. It doesn't even necessarily say what you think it does, and doesn't justify itself if it did anyway.

I'm not sure why you're replying then.

> All implementations are not equivalent w.r.t. all parameters; hence the various tradeoffs in competing designs.

I know, and not all are equally good.

Some Website? It's Wikipedia and curated; short of handing you a book (i recommend Tanenbaum) that is a good place to start from and then branch out of.

> It doesn't even necessarily say what you think it does,

That means you have not understood it.

> I'm not sure why you're replying then.

Because you made a untenable blanket statement that Distributed OS research was all wrong which cannot go unchallenged.

> I know,

I doubt it based on this conversation.

You definitely didn't understand the first thing I wrote, or you're deliberately misrepresenting it because you're intellectually incapable of addressing it.

Weasel words and Ad hominem attacks are not arguments; I had quoted your own words to you which leaves no doubt as to your position.

"Because you made a untenable blanket statement that Distributed OS research was all wrong which cannot go unchallenged."

That was not my direct quote, so you can dismount your high horse now.

And it's telling that responding to the question of why an OS should do these things, you finding a definition of an OS and asserting (falsely, I might add) that transparent distributed systems and only those meet that definition.

You apparently can't follow a chain of comments in a thread nor understand what is written down. My comment pointing out yours is here - https://news.ycombinator.com/item?id=40784174

Again, you have not read/understood what has been written down nor the sources to which i linked to elaborate my points. And also i never said "that transparent distributed systems and only those meet that definition". In my comment here https://news.ycombinator.com/item?id=40766810 i explicitly say "an OS is supposed to do viz. provide a uniform interface and transparent access to various Compute, Storage and Network resources wherever they might be." and then link to the distributed OS Wikipedia page for further details. If you had cared to even read that page you would have understood the key "Design Considerations" (see https://en.wikipedia.org/wiki/Distributed_operating_system#D...) driving the approach. It is the "User Experience" that makes a distributed OS approach so compelling; though its realization can be more complex/difficult compared to other approaches w.r.t. certain parameters eg. Scaling.

To summarize, i would advise you to read up on Distributed OS research before making silly blanket claims which can be easily disproved. Just because today the Cloud model has established itself as the industry standard doesn't mean that is the correct approach. You have to know both sides before you can argue for/against.

That's not the one I was responding to. I replied to the comment I was responding to, it's not that complicated.

> Again, you have not read/understood what has been written down nor the sources to which i linked to elaborate my points. And also i never said "that transparent distributed systems and only those meet that definition".

That was certainly the implication if you use that to answer the question, why must the OS do that.

You do understand how "The OS must do it because that's how I define the OS" does not actually say anything, right? Even if that is the definition of the OS (which it isn't), it just shifts the question to "why should the OS be defined that way?"
