Directly from the article: The machine, a cluster of powerful IBM Unix computers, has a total of 812 processors and 2 terabytes of memory, for a peak performance of 4.2 teraflops, or trillions of calculations per second. It took 31st place late last year in the Top500 list, a ranking of the world's most powerful computers by Jack Dongarra, a professor of computer science at the University of Tennessee in Knoxville, and other supercomputer experts.
But as it turns out, even the most powerful machine on Earth couldn't possibly replicate exactly the matter distribution conditions of the 380 000-year-old universe the Virgo group chose as the simulation's starting point.
Bob's emulation software SimH is a *fantastic* bit of kit. Runs vanilla OpenVMS without modification - VMS doesn't even know it's in a sim until you tell it so when you licence it.
Why is it a ridiculous password? Why is it any different from 18972345? Or 97852354? If you had fought your way to the control booth of a Minuteman silo i'm sure that you would have gone to the trouble of stealing the password so that you could use the damned thing - and by then it doesn't matter which number it is.
Indeed, I am inclined to believe that 00000000 is a very good choice because anyone who did manage to steal it would have a hard time believing that they did not have erroneous data.
I am only a little surprised that it was not changed from time-to-time.
Bittorrent and ISO downloading. We're in the UK so we actually have to pay more than 10p/year for our power too.
I also run a public-access VMS account service.
That's why we have to leave our computers on. Perhaps you could consider that your usage patterns aren't the same as the next person's before you open your mouth... huh?
I know what he means, and I totally agree with him. I try and fit filters over some of the brighter LEDs around.
For example, my girlfriend's PC has a magnifier in the front that puts out a 4cm-squared window of blue light. We fitted some pink paper to it and it's now a very very muted glow that doesn't keep us awake.
I don't need LEDs screaming out at me all the time - that's why my racks have dark smoked-glass doors.

Slight failure of basic logic here...
Yes!
:(
;)
Shame I live in the UK, really
Get over to classiccmp.org and post about it on the Classiccmp mailing list and you'll find quite a few people who'll help you get that space back
Aye, i've emulated an entire VAXcluster on a single-cpu x86 box with no problems. Bob deserves beer, and lots of it :)
My god, that's you?
*shakes your hand*
Thanks, i've referenced countless people to your page, it's really well-done.
A PC 5.25" drive won't read hard-sectored RX50 (DEC VAX) floppies. The world is not a PC.
You use your old VAX to make disk images for you before you give it to a collector.

DEC also refused to call any VAX a Mainframe apart from the 10000, which it deemed "Mainframe Class".
You can emulate a VAXcluster with multiple instances of SimH on a single-cpu x86 box with no problems.

(re-posting my anon comment)
DEC never made mainframes - there was one "Mainframe-class" VAX, the 10000, but DEC always conceded that the VAXen were minicomputers.
Don't get me wrong - i'm not beating on them. I have three of my own...

HAHAHAHA! You are the funniest poster I have EVER had the fortune to read! Go you!
PS: Lurk more.
You don't say.
We've seen it. Twice.
Lurk more.
I've never heard that one before. The traces on a VAX/VMS system should be wide enough to withstand that. I call BS.

Is this three or four weeks old now?
I'm sure you mean load value, not uptime value. An uptime of 0.8 days isn't really that impressive...
That would only take about a day to code and a few to perfect.
Go on then, scratch your own itch.
Er... so you can be contacted if there is a problem with your code? Don't use your primary email address, dumbass.
Hang on, you care about quality that much but you witter on about having DVDs?
If you really cared that much, you'd still be using laserdisc.
DEC had it with VMS on VAX, and later, Alpha. Multi-CPU clustering and seamless failover of all components in the system - software, CPUs, storage...
RIP DEC.
Contrary to popular opinion, London doesn't cover the entirety of England, Northern Ireland, Scotland and Wales.
Just y'know, FYI.

Sure, run an ISP in their own house... User? Define
You just did.
The user here is the ISP.
Wasn't that hard, was it?
I believe you mean missile. Been listening to that Dubyaspeak compilation again, haven't you?
