Factual 'Big Mac' Results
danigiri writes "Finally Varadarajan has put some hard facts on the speed of the VT 'Big Mac' G5 cluster. Undoubtedly after some weeks of tuning and optimization, the home-brewn supercluster is happily rolling around at 9.555 TFlops in LINPACK.
The revelations were made by the parallel computing voodoo master himself at the O'Reilly Mac OS X conference. It seems they are expecting and additional 10% speed boost after some more tweaking. Srinidhi received standing ovations from the audience.
Wired news is also running a cool news piece on it. Lots of juicy technical and cost details not revealed before. Myth dispelling redux: yes, VT paid full price, yes, it's running Mac OS X Jaguar (soon Panther), yes, errors in RAM are accounted for, Varadarajan was not an Apple fanboy in the least... read the articles for more booze."
Slashdot is dying.
It is official; Webalizer statistics now confirms: Slashdot is dying.
One more crippling bombshell hit the already beleaguered Andover.Net when Cmdr Taco confirmed that their servers have gone offline yet again, now down to less than a fraction their functionality when he was unmarried. Coming on the heels of a recent Kuro5hin survey which plainly states that Slashdot has lost its way, this news serves to reinforce what we've known all along. Slashdot is collapsing in complete disarray, as fittingly exemplified by being the most trolled website in the world.
You don't need to be Cowboy Neal to predict Slashdot's future. The hand writing is on the wall: Slashdot faces a bleak future. In fact there won't be any future at all for Slashdot because the Slashdot is dying. Things are looking very bad for Slashdot. As many of us are already aware, as the Slashdot servers continue to crash.
Red ink flows like a river of blood. For all practical purposes, Slashdot is dead, or at least should be.

From the article...
Varadarajan wanted a high-performance supercomputer based on a 64-bit processor and never looked at 32 bit. In addition, he felt that clusters imply gigabit Ethernet.
This is a pretty weak statement to justify the substantial increase in cost for the going to 64 bit and InfiniBand interconnect, compared to just buying more nodes.

d-: I love mac and own a G5, but you are a silly silly person. Macs have always let you get things done more quickly, but it is pretty recent that we can actually process everything more quickly and cheaply too (-:
I miss the SCSI days though.. I remember being on an PC and wondering "why the heck is it taking so long to transfer files and use the floppy drive". With Macs, I've always been able to get work done, the settings don't change themselves and programs don't mysteriously break. I'm a computer engineering major and I do a lot of graphics, so both are well fulfilled by OSX (though I'm not sure about Xcode.. especialyl the debugger, but I haven't had time to really learn it yet)

My photolog
Not after the last fiasco. I can't understand Apple's warranty department. They're virtually no help
I have a G4 powermac, a 1.42GHz machine which worked well and for the most part kept me occupied and did the tasks I needed doing. The noise however, was something that's been driving me, my wife and my pets crazy. The dog wouldn't come in the same room as she's scared of the thing. She also attacks the hairdryer in the bathroom, and I think that's a subtle hint that the thing was too loud and what it sounded like.
Looking deeper into the machine I found a couple of fans that when running at a certain speed reached a phenomenal noise level. With the computer in its cabinet they were bad enough but I felt like I was near a jet taking off if I had the Mac up on my desk. I pulled those fans out and they looked like they could be replaced by standard, quieter fans. I took one from the last PC I'd built (yes I'm multiplatform) and it fit well, so a quick trip into town I bought a pair and installed those.
The G4 was fantastic! The reduction in noise was something I could immediately appreciate, but my happiness didn't last too long. Within half an hour the machine was locking up and crashing. I opened it once more to see I hadn't been a moron and done anything stupid, when I noticed the apple supplied heatsink was BURNING hot. I mean really hot, I couldn't bear to touch it more than momentarily. I never trusted that heatsink, the sheer bulk of it looked like it was made to be produced easily and not cool properly. I ditched that heatsink (after letting the machine cool down for an hour!) and replaced it with a Zalman flower. I'd never seen cooling like it could do, so it was the logical choice. The heatsink for the G4 attached differently, but it was easy enough to adapt the zalman with insulated wire tied underneath the CPU board.
This worked a little better and the powermac booted, and stayed working far longer. For about three days, and from then on it wouldn't boot. No chime, just fans spinning and no video. Even the hard drive barely ticked a couple of times. By now I was furious, my previous macs had given me little trouble but this one was a pain. I phoned the apple center nearest me, and as it was only a few months old I was assured everything should be covered by warranty. It turns out because I had MODIFIED the computer that my warranty was void. wtf? I added a superior cooling system to the machine, quietened it, IMPROVED it in every way, and they deny my claim? I was livid at the store manager, but couldn't get past his denseness. Know what else? Apple keep on record what you've done. I replaced the original loud fan, the original heatsink and tried once more, and again my claim was refused on the basis I'd done the damage myself.
I'm still a Mac user, but a very annoyed one still waiting on repairs to my G4 that I have to pay for myself, and that I consider are Apple's warranty responsibility that they've gotten out of having to pay for by some stupid clause. Read the fine print guys.
Varadarajan is indeed going to publish/open source the documentation and source, which is clear if you RTFA. The parent is giving a false quotation, and is clearly a troll.
YOU ARE STILL UGLY

...so you're saying that the ONLY reason this article is such a macintosh worship-fest is because this moron just HAD to order his stuff in the two week period that G5's were "out" (announced, but not shipping yet) and the AMD's weren't. Poor fool, his two week rush probably cost him another million dollars.
A) Try pricing out some Opterons yourself. Be honest, and leave your fanatical Macintosh Religion at the door.
B) If this guy was honest and NOT looking for some much-needed $FUNDING$ ("Apple gave us no discount on our Macs, however they did donate $2.5 million dollars to build us a new library"), he could have had the same or better Supercomputer for less money with AMDs. You obviously don't know how we grownups play the game.
C) I don't talk to Anonymous Cowards, I believe you are all trolls and aren't worth my time. And you've just proved me right. And telling me to shut up doesn't prove your argument, it proves you try to censor the truth by silencing critics instead of learning and improving from criticism. That's the mark of a complete failure in life.
