[DNO] Scoring System Benchmark
Matt,

Can you post a siple loop script that runs for 30 seconds on your Scoring Machine? That way we can benchmark how fast our system is vs. the contest machine.

Thanks

Vader

php Code:
Original - php Code 
  1. <?php
  2. function getmicrotime(){ 
  3.     list($usec, $sec) = explode(" ",microtime()); 
  4.     return ((float)$usec + (float)$sec); 
  5.     } 
  6.  
  7. $time_start = getmicrotime();
  8.     
  9. for ($i=0; $i < 26000000; $i++);
  10.  
  11. $time_end = getmicrotime();
  12. $time = $time_end - $time_start;
  13.  
  14. echo "$time seconds";
  15. ?>


That runs right about 30 secounds, give or take a second....

Xeon 2.4GHz: 11.3 seconds... I'd better adjust my time limit to something much less than 30 :/

RE: [DNO] Scoring System Benchmark
Can one say that if this code works in 1/3 of the time (in comparison to the time on Matt's pc), that all code works in 1/3 of the time?

Does anyone understand what I'm saying?

My Athlon XP1800+ runs it in 13.6 secs. So that means that i 'll have to optimize my script for this time!

Yes i understand what you say but i am not very sure about it. I think as a rough estimate all code will run in 1/3 of the time.

Oups, 10.48757 seconds on my P4 2.4Ghz.
I guess I'll have to seriously optimize my program to finish 50x50 grids !

RE: [DNO] Scoring System Benchmark
matt. on a totaly unrelated offtopic:

why do you insist on using that function getmicrotime() when it can be done with:

$start=time()+microtime();

I guess I just don't like to rely on PHP's ability to convert a string to a float. I'm just used to the strict variables of other languages
