Reserving 40T-45T [Range 1] Ken_g6

cipher 2009-09-06 19:07

In range 1 we have:
21282782 falctors total
16429092 factored numbers
39248305 numbers total in 480000-484999.txt

~77.2% of factors are not duplicate.
~41.9% of numbers in 480000-484999.txt have been factored.[/quote]

Thanks Gribozavr, I send a PM to MooMOOO it looks like he is nowhere to be found also. Can any one else take over stats and Range Reserve/completion duties? Can you Gribozavr?

If it is possible I would like to be added a moderator to help out with this thread. All ranges complete, reserving 45-65T
[url][/url] for both previous ranges

I have not updated the stats, but if any one wants to update it and post it feel free. If there is any error in range reserved etc please let me know.

40T - 45T [url=]complete[/url] (Range 1)

Joshua2 2009-09-08 17:27

45-65T complete 1.45 factors / second. Reserving 65-90T

are all 3.6.4 versions the same speed? I had downoaded something slightly different I think. I'm going to try a X2 Neo and see how it does and it seemed the file was different when I downloaded it here. I run x64 on my C2Q and Neo. Any optimized versions? I have visual studio if that helps.

0.3.4/0.3.4a versions should be the same. I made a couple of minor tweaks that shouldn't affect the binaries at all a day or two ago. The _x64 versions are the fastest; -sse2 versions are 80% as fast, but work on 32-bit; and the plain 32-bit version is slow.

You might be seeing the difference that P size makes. Speed is proportional to log2(P/kmax), for P > 2*kmax.

Edit: Optimized versions for X2? No; but I benchmarked the 32-bit versions on an Athlon64. I expect it's about half as fast clock-for-clock as Core 2; but I would be curious whether the SSE2 version is faster than the 64-bit version (which I didn't try.)

Joshua2 2009-09-09 19:14

I'm getting 6.7M p/sec ~2T on range 2 on the Neo X2 64 bit. It is a ultraportable chip competitor to the Atom running on like 10W-15W. 256kb cache was a tad faster even though it has 512kb. I doubled the block size and made the checkpointing less often as well, cause I figured that would make it a little faster.

Ken_g6 2009-09-09 19:47

Did you try the 32-bit SSE2 version? It actually looks to be faster on my Athlon64!

Joshua2 2009-09-10 04:14

That raised it to 10.15M p/sec!
