Hey, All,

Just got back from a vacation to DC, and one of the places I went to was the Aerospace museum. There, they had a Cray-1, the first supercomputer. It has a computing power of about 140 megaflops. I laughed at this, but the person who was with me said that it was probably more powerful than my nice machine that has an e6750 core 2. I want to prove him wrong, so if anyone can provide me with the cpu's power in megaflops (or gigflops) or point me in the right direction to benchmarking software that will tell me my cpu's power in megaflops, i would really appreciate it.

Thanks,
Tekgek

SiSoftware's Sandra has the ability to test FLOPS.

Look under the CPU benchmarks, and they are the Whetstone FPU (MFLOPS) benchmark. Sandra uses the SSE3 instruction set etc, but the cray wouldn't of had that. So if you want to go oldskool just look on google for a FLOPS benchmark.

I found an oldskool one and it put my MFLOPS (3Ghz E6600) at an average of 1000 MFLOPS over the four runs it did, and that was only using one core, so technically its 2000 MFLOPS for both. Sandra puts the performance at 18689 MFLOPS with all the sse etc performance boosts. So use the Sandra result to show off more

2000 vs. 18689...something isn't quite right here.

I didn't link the random one I found as I don't trust it

But i don't know if the huge performance difference can be solely accredited to things like SSE boosts, or if the one i found was completely unoptimised, and the sandra is optimised. etc.

I trust sandra more out of the two anyways.

Okay, I ran a benchmark that I found. I ran it on my wimpy little, single core, celeron m 1.5 ghz laptop (which I am writing to you from), and it said that I have a score of 1,065,877 FLOPS, or 1 gigaflop. And now I get to gloat: "You thought that the cray 1 was more powerful than my good machine, but I crushed the cray 1 with a LAPTOP, A WIMPY LAPTOP! OWNAGE ", I said to him. That was fun.

What benchmark was it? That's some crazy high FLOP score.

I used Whetstone. It came as a single exe. You can get it here:

isnt 1000000 flops= 1 megaflop?

maybe that was not a raw score. I probably was not reading that right.

Yes martini161, I think these guys have to go back to school. so its 140,000,000 flops

there is a different between m and M.

You also have to realize that this machine is from 1968-1972, so its over 30yrs old, and just until a couple years ago, machines were just breaking this barrier. So if your happy you can beat a 30yo machine, that's great but you have to put this in perspective.

One of the latest crays can hit 101.7 TFLops ( 1x10^12 Flops)

And that being said Flops are great, but MIPS is really want counts.

it depends on what your doing, but yes generally MIPS are more important.

I do not think that I need to go back to school, but I get the point. I was wrong, and was seeing what I wanted to see. I apologize for the error and I hope that I did not mislead anyone into thinking that I was running a supercomputer in my garage.
