I replied to your PM. Overclocked results coming later this evening... Should be interesting to see if a 33% increase in clock speed equals a 33% faster time.

Got a few results coming in, thanks for all of you who are helping out. Looks like the time of 05:30:37 will fall today as that was his UN-OVERCLOCKED time.

Making the 2.4 GHz AMD box (used at the "baseline", and I do mean base) look really, really slow!

Excellent, this is what I was hoping for!

Results are at

The results should scale almost perfectly linearly since there is no floating point used and it is all done in RAM. If that is the case, it should take about 3 hours 40 minutes to run if you maintain a steady 4 GHz.

Overclocked and running now.

So do you think overclocking the RAM will have a noticeable effect on the benchmark times?

RAM is pretty darn fast. And, I believe, since the entire program is so small, if you launch it first, it will almost certainly fit inside the L2/L3 cache.

It would be tough to improve on those switching speeds. The speed of light is over 182,000 miles per second, which is about 983,571,056 feet/second. Call it a billion, and that means for every tick of a 1 GHz clock, a beam of light travels only 1 foot! At 2 GHz, light travels 6 inches per pulse, and so on. Cache switching is on par with this, surely within an order of magnitude, so overclocking this would have negligible performance gains.

The program may be small but while it's running it's using almost 900 megs of ram on my machine. Obviously it has quite a bit of data to manipulate but I don't know how often it has to move that info around to know if the memory speed will make much of a difference.

Ahh, yes... correct. I forgot, this is the unbuffered version.

OK then, scratch that about the cache, of course.

it's rarely MOVING data in RAM. Every position is given its own byte. So, it's fetching and overwriting mostly, all in contiguous blocks that are allocated on startup.

I added a link to the fastest solution's report file

It was interesting to see that you solved the entire 2-piece and 3-piece databases in a total of 2 seconds!

Here is a link to the "report of the champion" with the fastest confirmed solve time.

http://www.liquidnitrogenoverclocking.com/report.txt

Something else you might like to search for after you complete the solve then have your report. Open the text file, and do a FIND on

#################### This entire database was solved in

It will give you the times of your 2-piece, 3-piece, 4-piece, 5-piece, and 6-piece databases, tracked separately.

lets see what she can do

running on the benchmark on my buddys athlon x2 5000 @2.2Ghz for the second time, last time someone CLOSED the program 5 hours in......will post results for you soon.



I will also be running the program on my AMD Opteron 1.8ghz OC'd to 2.2Ghz as soon as i find space to hook it up. It's old but im intrested to see what this relic can pull off.

In Japan, I think they chop off a finger if you do something like that!

Very cool, and thanks. And, if you haven't seen it yet, I linked in a form where you can copy the text from the report.txt file and just send it to me.

It's here:

...and also available from the benchmark results page here:
