Hi All,

Could someone post super pi mod 1.4.

A group is comparing results and they've chosen mod 1.4 to use as bm.
I've got 1.5, I don't think there's a big difference, but they want us
to post a screen cap to verify. I suppose I could get creative with PS
pro, but that wouldn't be honest!!!

TIA

Al

P.S

If you've got one that works, that would be great too!!

Here is Pi to 300 signifiant digits

In[1]:= N[Pi,300]

Out[1]= 3.1415926535897932384626433832795028841971693993751058209749445923078\

And here is Pi mod 1.4 to 200 digits,

In[2]:= N[Mod[Pi,14/10],200]

Out[2]= 0.3415926535897932384626433832795028841971693993751058209749445923078\

The only difference is the owner of the software was changed in the about
page

http://www.xtremesystems.com/pi/index.php

Changelog:
2005/02/21First version

2005/02/21Fixed minute bug (1:20 would show as 1:80)

2005/02/22Super pi mod now loads/saves the result times in msecs in
pi_rec.dat. The original pi_rec.txt is no longer used in this version
because it just wasn't worth the trouble. Super pi originally stores the
results in seconds internally so I had to do quite a bit of editing to get
this to work at all :)

I changed the text in the title bar so people can see that you haven't
cheated when you post a screenshot with your results.

2005/02/27Added more cheat protection. Try to cheat and it'll crash :)

2005/02/28Moved the code around a bit and changed back the section
permissions.

2005/03/04Restarted from scratch.
New features are an even more precise timer, no more 15 msec jumps.
A checksum has been added which you can validate using the form above. Also
results are now saved in an encrypted format for the jokers that like to
edit the save file :) Your old results will no longer be loaded, a new file
(pi_rec.dat2) is used. Sorry about that but it was the easiest way.
2005/03/14I had to go back to the previous timing, 15 msec jumps are back :(
Problem was the high precision timers were giving completely wrong results
on systems clocked over ~4 GHz.

2006/02/14XtremeSystems branded Pi released!
No physical code changes other than heading at top of dialog box.

## Re: Super pi mod 1.4.

One other question. I looked at task manager while super pi mod 1.5
was running. It shows both cpu's (P4 640) running at ~50% during the
calculation.

When I run other cpu benchmarks, (sandra for example) both cpu's are
at 100 %.

Should super pi be utilizing 100% of my cpu's resources during the
calculation???

Thanks,

Al

The author wrote the program before Dual Cores became popular.  He has since
lost interest in the program.  So it will be up to someone at xtremesystems
to decide if it ever modified for DC
