Hahaha!! :D
run QuickPI so we can share results :)
and of course we can calculate much more than 1 million since its soo fast.
100 Million should be a nice test.

where do you find it?
Goto http://home.istar.ca/~lyster/chart.html
there you find all you need
On an E8400 @ 3.6GHz, 4GB DDR2 @ 800MHz 5-4-4-15....
1 Million Digits: 0.67 seconds total
100 Million Digits: 163.52 seconds total
1 Billion Digits: 4453.81 seconds total
Human math is flawed. We cannot resolve Pi with our inferior numbering system nor can we quantify the calculation power of our own brains with our metrics. We need to think more like the Progenitors...
Neat program though.

Is it single threaded or multi threaded?:D
Its multi threaded.
Single from the looks of it. ;) Only one of my cores is maxed out.
It doesnt show up to 100% cpu utilization on 4 cores but its automatic multi threading.
You can even specify how many threads should run.
command line: qpi 1000000 -stats -threads
133.33% utilization! :rofl:
Not bad, by the way, the application closes down when I 'press any key' as it says. :confused: Doesn't work.
Hmmm start it from a command window?
Bah, I'm tired.
