Whoops, no Super Pi scores here, but I do have a question.
Why Super Pi?
I have always wondered why Super Pi.
It's slow, not dual-core optimized, and can only do 32 million digits max.

Has anyone ever heard of qpi?
Here's my scores, this was while I was listening to music and doing other stuff, browsing firefox, etc.

(That's 1 minute, 36 seconds for the whole thing)

The theoretical limit is 1 billion digits for a 32-bit OS and a 64-bit OS has a theoretical limit of 500 billion digits. This program can also calculate other irrational numbers...
Catalan's constant, natural log, Euler's constant, natural log of 2 or 10, golden mean, and others.
You can even train the program for your computer to improve performance.

we use super pi because it is universal, there's no "training it to be faster on your computer."
also because it is straightforward, fast, with the xs mod it will tell you thousandths of seconds, and it has a checksum so you can't cheat.
even though it's single threaded, your scores can vary greatly between single and dual core processors even if they are running the same speed with the exact same hardware...

I get better times with all four cores enabled than I do with two cores.

So it has a checksum, what reason does someone have to cheat? What do they gain from saying they got 0 seconds?

You don't HAVE to train, it's a side thing, I didn't train, it's just using the default data.

And yes, I get better scores with two cores than one core on Super Pi, but it's a very slow algorithm, and I just wanted to know if anyone was aware that there are faster programs
