super pi

J/c, once again about my MBP that will hopefully arrive sometime before I die (Apple, you should really open a store in New Orleans or Jackson, MS so that people from the gulf coast don't have to drive 6 hours to the nearest store!!). I'm getting the 2.2Ghz with a glossy screen, and me a friend were testing out super pi on computers around the house. My poor old desktop ran 2million in 3 minutes 24 seconds. I was just curious as to what the MBP was running. It would be helpful if ppl could repy with your stats and the configuration your running. I tried finding in on the web, but I could only find stats for the 2.4 (53 seconds) and last generation MBPs. Thanks

MBP 2.2 GHz being shipped, Choose

I don't know if super_pi is the ideal software to benchmark a MacBook Pro, as there is no Universal Binary version nor sources today (or if you have found something, give us the link !)
If you want to try with the Windows version under bootcamp, or using Roseta here is the homepage :

Also, to calculate 2M digits of Pi, you'll have to use 21 as the parameter.

./super_pi 21

I just tried it in Terminal on my mac Pro and it only uses one of its 4 cores. That was disappointing. Regardless, with a parameter of 21, 1 core came in at 62 seconds…

End of calculation. Time= 62.282 Sec.
End of data output. Time= 0.398 Sec.
Total calculation(I/O) time= 62.680 (11.663) Sec.

super_pi is single-threaded - it will only use one CPU. The calculation of pi is the type of operation which can't benefit from multi-threading and multi-processors, since every step depends on the result of the previous step.

Hmmm, there might be an algorithm for calculating pi which can be threaded... I don't know of one.
