CADO and WinBlows

akruppa · 2013-01-23, 16:06

We're currently in the process of improving portability of the CADO NFS tools, in particular we're trying to get them to compile under Windows. There are a bunch of annoying catches, however, and we're taking stock of the options. One option that was discussed was simply preparing a Linux environment for a Virtual Machine under which CADO could run, with minimal porting work on our part.

So we were wondering how much demand there actually is for CADO on Windows, and whether a VM solution would be considered acceptable.

If you are interested in running CADO on a Windows system, can you please tell which Windows version (incl. 32 or 64 bit) you are running, and whether running a Linux CADO in a VM would work for you?

I would use CADO for Windows 7 64-bit.

How good is CADO's siever in comparison to ggnfs's?

It's under active development, which is a rather big plus.

(In all seriousness, I'd love to see some numbers, like everyone else

)

I doubt it would beat the 64-bit asm but it might stand a chance against the 32-bit asm(which is all we have on windows).
Anyone got numbers?

I can run a comparison on Linux, maybe with polynomials for one of the current team sieve projects. The Windows build does not work yet (tho it appears we're getting closer, now it seems to be mostly a matter of parsing CRLF in the scripts correctly); once it works, I can post a comparison for 32-bit builds on Windows.

This team sieve could handle some extra relations.

1M for each siever would be a reasonable large-scale test. That's around two days on one core of an i5-2500, so perhaps splitting a 1M range among the various sievers would be better.

Hi
It would be nice to have a version for Windows 7 64 bit, I mean a native version, not a virtualized one.

henryzz · 2013-02-21, 23:27

TBH I would recommend making a full windows version now. Eventually I would guess that bits of the CADO tools will become a regular part of people's toolset. It would be better to convert it earlier while the project is simpler than later when it is more complex.
We don't want a situation like we have with the 64-bit ggnfs siever.

Is the Windows version going to use the GMP libraries or the MPIR ones?
