你都沒設參數就給它跑下去喔...288.28S??? 不會吧:eek:

不會啊∼
如果你是設定我說的參數,
這樣算很讚囉!

兄台的記憶體很大啊!
超一下吧!
成績應該也挺可觀的喔!

以前懷疑記憶體有問題的時候
SuperPi還不見得會死, 但是pifast跑一下就重開機了.....

4.3版

Current version : PiFast43 (version 4.3, released on Jul 05 2003, fixed on Jul 08 2003).
New features of version 4.3 :
* Faster than previous version : 4-5% for pi computations, and more (10-15%) for
e computations
* A serious (but rare) bug discovered by Shigeru Kondo in the computation of
64 million digits of e=1/exp(-1) was fixed. The bug existed since version 4.0
* Ability to specify a factor suffix k,K,m,M,g,G after the number of digits
(k=1000,K=1024,m=1000000,M=1,048,576...)
* Maximum number of digits is now 17 billion (instead of 12 billion with previous versions)

一年前就玩過這個了,當時還拿quickpi來比較
quickpi在數值不大的時候比pifast還快很多
(而且記憶體使用量極大)
不過最新版pifast好像比quickpi快了

用了最新版的pifast43算32m

pifast43 windows xp sp1
Series computing time : 187.56
Division time : 22.59
InvSqrt time : 9.02
Final huge multiplication time : 7.45
---------------------------------------------------------------
Total computation time : 227.38 seconds(~ 0.06 hours)

pifast43 windows server 2003
Series computing time : 183.31
Division time : 21.78
InvSqrt time : 8.73
Final huge multiplication time : 7.14
---------------------------------------------------------------
Total computation time : 222.70 seconds(~ 0.06 hours)

Windows Server 2003果然是強悍!!!

我的配備
P42.4CG
