fnsieve - Page 4

I have reposted the zip file with 32-bit and 64-bit Windows executables. I have no way of testing the Windows builds as the Windows box I produce the build on does not have a GPU that can run the application. Hopefully that will change in the near future.

I'll try Win64 version on a HD5870 GPU by the end of the week - I will let you know.

I was just trying to launch both fnsievecl64 and fnsievecl32 (both under Windows 8 Pro x64) however I am always getting "Fatal Error: First line of the input file is malformed" message.
I tried generating input files using srfile with different arguments -a, -g, -G, -w for a sequence of 7666*10^n+1 - no luck

Send me your input file and I'll take a look. It's probably a relatively stupid bug.

I have moved fnsieve to here. as the old link is gone. The OpenCL version does not have factor validation, so I need to add that before posting it again.

Thank you, very nice.

Small suggestion/request: Only output all the factors to screen if verbose -v and/or -f is used? It spams very much and the scrolling probably slows it down a bit.

I could use -q for quiet mode, but then I miss the stats regarding "p/sec" and "sec/n".

What is the max range of "c" ? Is it just limited by the RAM?

Use -m with a really high value to avoid outputting factors.

The min and max for c is -2^63 and +2^63 (IIRC). You are limited by memory.

Sorry I missed the -m option, that works fine.

The interval cmax-cmin seems to be limited at 2^32, it crashes above that, but that's ok.

Hmm. I'll look into that.

Is this the fastest program available to trial factor a single k,b,n,+-1 pair? If not, which program is the fastest.
