1 Petaflop Supercomputer

Funny you should mention that. I now have the name of the manager running the testing. I can drill down through the organization and find the project manager.

Seems IBM tested theirs for awhile on RC-5.

I'm not making any promises... but let me see what I can do. No harm in asking. 🙂
 
Let's see here... this machine was supposed to have 2,728 Alpha processors. If calculated at 667 Mhz and doing the same rate as a celeron (I have no idea about Alpha performance)

That should yield 1819576 Mhz or in other terms:

This machine will crack 5.09 Gk/sec or do 1,639,838 blocks per day.
I wonder how many days we can wrangle?
 
Ah, I think the Alpha's are more efficient than the PPro relatives... in fact I think they're either the PowerPC 603 or 604 from the speed calculator...

that would yield 6GKey/s or a total of 1,932,666WU's/day 😎

/me crosses fingers and hopes you can get it for a day or two Dan 😉

With love and respect your fellow TA member

unfortunatly I have no stats to back this up, but I recall the alpha blew at rc5. I might be completly wrong but even if they cracked like 486's the darn thing would still put out keys!
 
I seem to remember the same thing as Possessed Freak... The alphas suck at RC5.

But, when you throw such an enormous amount of power at it, the results will still be impressive...

Looking at Dnet's speed page (http://www.distributed.net/speed/), it appears that an Alpha at 667Mhz puts about about 1.34Mkeys/s (100Kkeys/s faster than a celery 450).

With 2728 processors, that works out to 3.66Gkeys/s....

Definitely would be a nice addition to the team!!!!!!!!!!!

If I remember correctly, IBM did test the world's fastest supercomputer on RC5 for like 6 days or so. In those 6 days it was faster than any other TEAM....pretty amazing....
 
Hehe, Alpha's may be slow, but boy do they kick butt in those kinds of numbers.😀
