Default Citrix' revision to srsieve

I rewrote sr5sieve using the idea mentioned in PSP project forum and I found 3 factors. time per factor = 240 sec.

Is this of any use to anyone?

8002393997041 | 99926*5^1786093+1
8004199695841 | 66916*5^1544589-1
8009635921921 | 92936*5^1315448-1

Machine used = celeron 1.4 ghz RAM=512 Mb L1=32 L2=1024

Hi Citrix,

Thanks for the heads up - I uploaded the factors on our factor submission webpage; the factors appear to be new. Can you give us a link to the source? I saw some discussion at the PSP forum, but no mention of working code. Can you give us a brief overview of this software?

regards,
masser

It is here in this thread.

I just modified the 'y' version so it works for base 5. Geoff will be able to compile it better and reduce the time further.

I used y=720.

Instead of y it should be the x version in the previous post.

Does someone have a working version for SR5sieve "x version" (amd or intel, i don't care). or even a SR1sieve "x version".?

sr2sieve (including the -x version) can sieve in any base, you just need to rename the work file to sr2work.txt and the input file to sr2data.txt, or else specify input with the -i switch and specify the sieve range with the -p and -P switches.
