Why is Cray, a cutting edge supercomputing company using AMD and not IA64?

I forget the details, but the cray of the past is, unfortunately, no more. the cray these days is just another tech co.

..huh, ..what a statement - "just another tech co" eh?

http://www.cs.sandia.gov/platforms/RedStorm.html

..and some more detailed reading:

http://www.cray.com/products/xt3/index.html

This is where Opteron and the quality of AMD really show in true light. Cray (as always before in history) sure knows very well what they're doing..

cray is good but nec's sx-8 is the top.
as i said, nec(vector) and sgi(non vector) are the two leading companies these days.


Sure SX-8 and Altix 3700 are the most powerful single cabinet systems, but at what price/performance (and power consumption)?

Edit:
..by the way, do you know what is the most powerful single rack-chassis system?

no, they're the most powerful single-IMAGE systems!

but at what price/performance (and power consumption)?


who cares at this level?

it doesn't matter. it's all about smp or not smp and bandwidth.
anything can be clustered...

What is 'powerful' supposed to mean?

Does the system:
- consume the most power?
- have the fastest CPU clock speed?
- have the most CPU cache?
- highest number of transactions per cycle?
- highest number of transactions per second?
- highest number of interconnects?
- highest efficiency of CPUs?
- least drop off of CPU efficiency as the CPU count increases?
- lowest latency between furthest CPUs?
- lowest cost per transaction?
- highest throughput per transaction?
- highest peak throughput?
- highest sustained throughput?
- throughput between what and where? CPU and main memory? or disk?
- and what's a transaction? LINPACK? Oracle? DB2? What type of transaction in those databases?

And I could go on.

Any numeric comparison between *different* computers is essentially useless.

There is no 'most powerful' uber system :roll: I can show you a client who thinks their Origin 200 database server is the most powerful computer they have - even though it has less CPUs than their Sun E6800.

Cheers,
TOM

..so you dragged a discussion to comparing vector processor systems to the scalar ones???

Guys!

Besides, according to top500.org, an IBM PowerPC based machine called BlueGene is top ranked at a theoretical performance of 91750 GFlops with a peak performance of 70720 GFlops which is almost SGI's / NASA's Columbia AND NEC's Earth Simulator put together!

this ranking is useless.
it's just the number of cpus. look at Rmax and Rpeak or how many cpus are needed to get the
result.
i could cluster 87324875324852384 ipods and beat the ibm... got it?

man, that'd be a lot of MP3 ripz... Instead, I'd use PSP's and make a huge Trinitron colour screen visible from space. by covering about 10-20 acres of ground with 'em.

You could use 15" LCD's and each one could be one pixel 8)
