Burgi

i'm going to compile an answer based around the impact on games

qasdfdsaq

@Burgi Honestly, IMO the names may end up changing but the overall landscape of the tech industry would be the same as it is now

Everyone is doing the same thing, numerous companies from all over the world are all competing in the same markets. If one were to disappear, we'd just have another with a different name.

Burgi

maybe

qasdfdsaq

We might have Myspace instead of Facebook. Yahoo instead of Google. Linux instead of Windows, etc.

They'd still end up doing the same things, with the same broad market strategy.

If you look at what tech companies are doing today, none of them are particularly unique. They're all doing the same thing, in slightly different ways.

Burgi

11:57 AM

Windows would still exist but possibly run on different hardware

RISC chips would probably be dominant in desktop machines

Journeyman Geek

We wouldn't have SGI tho

and maybe sun

qasdfdsaq

Would it? Would Intel, AMD and Via all be entirely wiped out by a small geographical incident?

Journeyman Geek

isn't via taiwanese?

@Burgi windows was designed to be architecture independant.

Just that realistically there's no real market outside the big two architectures

qasdfdsaq

@JourneymanGeek Which two would that be?

Journeyman Geek

Arm and x86_64/AMD64?

qasdfdsaq

12:10 PM

Eh.

Journeyman Geek

longsoon (which is mipsish) only exists due to government assistance, mips...

qasdfdsaq

I don't know enough about the technological differences. But a decade ago there was PowerPC, Itanium, MIPS, and so forth.

IMO Windows is irrelevant - it just has the dominant market position as a result of the circumstances. There's nothing on Windows that couldn't have been done on Mac, Android, or Linux.

We may even have ended up with OSR2 or IBM Unix being dominant, but it doesn't matter. Over 30 years development would have followed market needs and demands in the same way.

@tereško What a load of rubbish. Console manufacturers know full well the human eye can see more than 30fps, they deliberately cap at 30fps for reasons that have nothing to do with what you can see.

'sup, Super Users? I'm currently trying to get a Gentoo Prefix set up (on a machine that actually runs Gentoo, funnily enough). I grabbed the bootstrap script and ran it, and somewhere along the line, the prefixed Portage broke. Looks like the portage Python module disappeared; trying to run the prefixed emerge gives me a Python ImportError. Anyone had this problem before?

Portage uses Python 2, right? Oddly enough, there is an $EPREFIX/usr/lib/python2.7/site-packages/portage, complete with __init__.py and not few other modules. Hmm...

Even odder, invoking the prefixed python2 directly with -c 'import portage' works fine (the non-prefixed one gives that ImportError). As far as I can tell, though, things in this environment should be using the prefixed Python; the prefixed bins are at the front of $PATH...

Burgi

12:59 PM

@JourneymanGeek what i meant is that if you think of windows you think intel x86/x64

qasdfdsaq

And a 24-core system is 192-thread

It's a bit dated though.

The z196 is a 45nm part from 2010.

qasdfdsaq

Despite massively different companies producing massively different architectures, Intel, AMD, IBM POWER, z/Arc, plus loads of different mobile architectures were all fabbed on 45nm processes within a couple years of each other.

Bob

tomsitpro.com/articles/ibm-mainframe-z13,1-2414.html

qasdfdsaq

Sounds like the mainframe z/Arc is a class above what the POWER8 is aiming at

Bob

@qasdfdsaq Probably.

IBM claims it to be the most powerful CPU available.

qasdfdsaq

And the POWER8 is already somewhat above the Xeon class, and barely competes with it only when you cut prices extensively on the IBM

Bob

2:23 PM

So it should at least beat whatever POWER they have.

~10 TB of RAM though O_O

qasdfdsaq

Eh that's not really all that impressive

10TB of RAM across 168 processors is about 60GB per CPU

Bob

And that's just the usable space.

I don't know what the ratio of usable to physical is for RAIM.

qasdfdsaq

Intel's E7 series support 1.5TB per CPU, so 12TB in an 8-way system

Journeyman Geek

168 processors is pretty impressive...

qasdfdsaq

Yup. Intel are trying to get into that market with their OmniPath architecture

Hennes

Suprisingly enough win10 recognised it out of the box.
win7 needed drivers.

also surprisingly win10 recognised an E2400 Killer NIC, but not the very plain Itel 219 NICs

qasdfdsaq

That's because Intel 219's are extremely new

Y'know I'm tempted by those Mellanox 10GbE cards now.

I'm pretty sure last time I looked at them they weren't supported on my virtualisation platform. But a) I'm not using ESXi anymore and b) They seem to work on Linux

Odd. Their support page denies it's supported under Windows at all.

And apparently it's not supported under 6.x Xensever which I do use, but there are drivers for RHEL 5, 6, and 7, which Xenserver is based on
