cipher:
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?

thanks

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.
reserve 2t-10t range 2

Ken_g6 2009-09-09 15:09

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!
