Maybe, but look at the free advertising VT has got out of this? The whole tertiary computer world knows that VT has the fastest supercomputer. And now when they change to Xserves, they get a second round of free advertising.

And how many computer geeks and boffins have and will trek to VT for a look?

And wouldn't you want to work at or attend VT with the reputation they now have from this?

This has and will put VT in front of people for over a year! That's a good return on investment! 🙂
 
If I was them, I would have waited for the next Xserve update, probably in September. But I expect the savings on the electricity bill will make it worth it. The PowerMac G5s will be used in the University by students and teachers, I expect they have some old G3/4s that need replacing.

Anyway, i hope that the xServe form factor and the proven Super-success of the platform will push someone to go after #1. Oh and the damn good pricing.
Unlikely 🙂 Next year IBM will bring the complete BlueGene/L super computer online. It will aim towards 350 TFLOPs, 35 times faster than VTs cluster.

I'm just wondering why VT is deciding to upgrade now, when the G5 is scheduled for a 50% speed upgrade within the next 6-9 months. Won't this just be wasted $$$ in the long run? Sure it would be nice to cut the cooling costs for a few months, but when they upgrade to 3GHz XServe G5s they will have a much more ass-kicking Mac monster at their disposal.

In 9 months the G5 will be 6-9 months away from another 50% speed upgrade.

It NEVER makes sense to buy a computer, because there will always be a faster, cheaper one if you wait just a little longer.
 
Do you think that maybe another academic institution may be getting their current G5's ???? or they will be upgrading their network to a full mac suite or maybe going to the staff / students at discounts.

Maybe this system was a test bed, dont forgett they got the first shipment of G5's and a completely new architecture, this thing wont have had much real world experience and apple may have offered them a 'Proper' system if they wanted it, to run their projects on e.g. the Xserve systems.

Doesn't look good for apple marketing if a supercomputer is made up of their Desktop Machines and not their servers, what does that say of apple's servers, this has always been a weak point for apple, their servers have never been really upto scratch until the xserves came along.

Its like a company saying to HP/Compaq,, hmm no we wont use your Proliant ML Servers we'll use your EVO Desktops... doesn't happen.

All i can say is this is looking to be a promising future for Apple Servers, I hope they exploit this, who knows a 3u Mac Server next?? Just look at the flexibility this one has offered, and of course its all thanks to the w

But will it play Solitaire?

no surprise there

this was probably planned along with the original purchase. And I bet there's alot of VA engineering students who will love to have those Power Mac G5s for their departments!

The long term energy savings will be large and with the Xserves and time is an issue a 6-9 month wait is not an option. Plus now they can add faster Xserves to the cluster when they come out.

I don't think so. They would only be able to say such things if Virginia Tech would replace the G5’s by Opterons or Pentium Xeons. Since they only change one G5 system for another it makes no difference to their commitment to Apple.
 
Re: Re: Network cards

VAtech is using infiniband. It's faster/lower latency than ethernet. Likely they'll just move the cards over.

But why not keep 2/3's of the towers, replace 1/3 with xServe G5's and end up with like 1700 boxen. Mmm.

Because the cost of the upgrade will be paid for by the sale of the PowerMacs currently in the racks. Even if they only get 80% value that means the upgrade only costs about $660K whereas if they keep 2/3 of the towers then your looking at a cost of around $2.4M.

XServe uses ECC ram which is much more suited to supercomputing than the regular ram used in the G5 tower.
 
So, after they upgrade to all Xserves is it still ranked #3??? I mean, isn't it really differnt supercomputer and not the one that was originally ranked #3. How is that going to work.
 
has anyone checked the VT web site to see if you can sign up to help provide a "very good home"?
 
A bird in the hand . . .

One can always make that argument. It leads to nothing getting done.

Since VT is undoubtedly aware of the SJ's promise to deliver 3ghz desktops by June, they must have decided it was worth it. There just may be details involved that we aren't privy to. Imagine that.

Good question. I imagine they'll have to get it re-certified.
 
I'd really like to see them adding a few more nodes in the proccess. it'd be kickass to steal the number 2 spot. Until IBM gets their behemoth online, that is 😛
 
I have a friend who would love to purchase one of those babies. Guess it's off to the VT website for him.
 
Being the caring, generous, unselfish, and helpful type. I could *ahem* give my precious room to store a few G5s, maybe 1... or 2... or 1100... 😀

But seriously. I wonder if Mr. Varadarajan and the others have considered donating them to the less fortunate mac users? All I have is an old iBook that barely works anymore, and Apple refuses to acknowledge the fact that the logic board is frail. I guess it was my fault for just going out and buying one when I finally saved up enough.

woe is me... and my lil ibook g3...

Unless they did some serios advertising, the will sell for very little.

Unless they are smart and release them at a trickleing pace as oposed to all at once.
 
i wonder what you'd have to do or who you'd have to talk to in order to get your hands on one of those g5's for cheap?
 
As for upgrading and not going any faster at VT,

I think the space saved will be wisely used, more space might mean they can house more machines in future, 2-3 times as many actually, now how would that compete in the supercomputer rankings?
Anyone care to guess?
