Speed report: Old timings are sr1sieve 1.1.12.
Core2 Suse 64-bit: 11.1 mp/sec to 12.6 mp/sec. 14%.
X2 laptop Suse 64-bit: 4.1 mp/sec to 5.3 mp/sec. 30%!
This makes athlons even more specialized for sieving. Interesting, eh?

Speed measurements are from the current k=5 sieve.

Is version sr1sieve-1.2.2-linux-x86-64 safe to use?

Edit: NM, it's slightly slower than 1.2.1 on Gentoo x86_64, or perhaps posting this question slowed it down.

I am using this version some time now without a problem, but still it is marked as experimental.

The latest sr2sieve version is now 1.6.13. Trying it on my Athlon right now.

It seems that beginning from 1.6 he has only a single exe file for both Intel and AMD cpu's, before there was one for each of them.

Is anyone using the 64 bit windows version (sr1sieve-1.2.2-windows-x86-64)? Should this run on Vista 64?

Yes, that's the version you should use on Vista 64-bit. I haven't ever tested any of the 64-bit apps (don't have a 64-bit machine myself), but they should provide a 2x speed increase over the 32-bit versions, from what I hear.

I've executed "sr1sieve-1.2.2-windows-x86-64" on two Vista 64-bit operating systems with the same results:

"Faulting application sr1sieve.exe, version 0.0.0.0, time stamp 0x4731ac12, faulting module sr1sieve.exe, version 0.0.0.0, time stamp 0x4731ac12, exception code 0xc0000005, fault offset 0x000000000000745c, process id 0xd38, application start time 0x01c83162273cf469."

This happens just after the output:

Read XXX terms for XXX*2^n-1 from NewPGen file `XXX.txt'.

Are you sure that you're using Vista 64-bit? If you're accidentally using it on a 32-bit Vista installation, I can imagine why it would give an error at that point in the output--that's when it would be starting the main computation code (the part that would actually use the 64-bit features, I would think).

If you know that you're definitely using the 64-bit version of Vista, then I would recommend downloading sr1sieve again--maybe something got messed up during the download process, and your copy is corrupted somehow. And if that doesn't fix it, I have no idea what's going on--maybe Geoff can have an answer there, since he wrote sr1sieve.

AFAIK, A 32-bit kernel cannot execute a 64-bit binary at all.
