[citation][nom]Sam Buddy[/nom]The trade-off between power and performance, is strongly in favor of IBMs PowerPC.I'd rather buy 116,000 PowerPC A2s (consuming 3,480kW), which would equal the performance of the 98,304 SPARC64 IXfxs (consuming 11,600kW), and save tons of money with PowerPCs lower power consumption. Plus, it's more eco-friendly.[/citation]
Good point but I think the article is missing some key details that might change your mind.
1) The cost of both systems. Granted both would be extremely high in their most maxed out configuration but it the Fujitsu solution was say several hundred thousand less, might make power consumption a moot point.
2)Physical limitations of both systems. The article does state the number of racks for the Fujitsu system but not IBM (although I'm sure it exists elsewhere) and while the number of racks is a helpful number it does not state if that is a "turn key" setup, meaning, they don't say if other equipment is needed which could, depending on the equipment could be just as many racks.
3)And this may be the biggest point missed in the comparison, support. That's right folks even supercomputers come with warranties and tech support and at this level it is a HUGE factor. Now most of the places that have computers like this installed have employees that could, in theory, support them but when you have a multi-million dollar investment sitting in a data center. It is get really hard to justify to the top brass that they let a guy who they pay less than $60K a year replace a hard drive on such an expensive piece of equipment. Nope, they hire contractors, buy support contracts or call tech support and all of that comes from the company they bought the machine from, this is where IBM really makes their money.
I'm not trying to say your point is wrong, in fact I think I would go for the IBM if I was in the market for such a beast. Just because IBM has been doing the supercomputer thing for a while now and their support staff in my country is probably more plentiful than a Japanese based company.
Just my 2 cents
