I guess I'm more geared toward the subproject goals, right now, so I'm less inclined to hang onto these to see where they head. I did keep 802284 for now and have it running on a 24/7 machine, but if I keep too many, I won't be helping the subproject as much. Maybe at some point I'll pick something back up, if no one else has.

Maybe I should put an older (slower) machine onto those "hopefuls"...

Done with 800922, 118 digits, 2^3*3

What I do is use -q to run only one index and alternate between several sequences. This allows me to have 10-13 sequences without drivers and only one processor dedicated to them.

Do you have a script doing this stepping or are you just checking them manually when they finish an index?

I asked if a similar activity would be of interest for the aliperl.pl script project and it didn't seem to be. That one would have moved several sequences one digit at a time, but I might see if there would be a way to add one index at a time processing if there is an interest.

Of course that might be better as a different script rather than overloading the one we have.

do you want either cause i would be interested in 1 or both of them?

I am using a very simple batch script which runs each one once, another script 'runmulti' that runs the simple script 20 times and then 'runmultimulti' to run the multi script 20 times.

I haven't been paying too much attention to the aliperl project. A simple loop over sequences done once that gave a count on which iteration of the loop might be of use. Right now 'runmulti' outputs prog.txt, with 'first run', 'second run' (using a simple echo) so I can see how far it has gotten. It breaks down at 20 however when it goes back to 1.

Note that I have been thinking of trying a different approach which is to modify aliqueit.exe - stopping at a certain number of digits, or when a cofactor is a certain size (so stop post ecm). More complex would be to stop at a certain number of digits only if it has a driver (so stopping at 100 digits with driver, and 110 without would be possible).

If you notice a few lines added to 804462, that was me playing without reserving yet. Not that I want that one. I was just getting ready to take it because it was one of the last in that group.

aliperl actually didn't start out to be what it is. Its inception was from my work trying to complete a bootable CD/USB aliqueit package. I have a running USB version, but I'm not able to use the new factmsieve python script yet. I'm also still working on the CD version.
