All of my params files include a target number of relations, so I would be able to tell when your runs use one of my files because the number of relations found would be just over my target number set.
Also, my files use a substantially larger LP bound than default, so the number of relations is quite a bit larger than default settings.
The only item I'd want that wasn't in your paste of the data dump is the size of the input number.
For my own data-gathering, I record Q-range sieved (which isn't in the summary, but also isn't that important), poly select time (size and root, but total is enough), sieve time, bwc time, wall-clock time. Recently I've been also recording the total weight of the matrix (the number printed just before linear algebra starts), so that I could see how various density selections influence matrix size; again, not too important but if we start collaborating on C150+ settings it would be nice to have.

I encoded the composite size in "<XXX>" right after the N in the first line:
Code:
 N<138> = 107858998268122985412779892463164903278148452826296404480200645178455386381787979632919305998206531705192000227253731053070278282139941833
I put it there instead of at the end, so it would be more accessible.

I'll work on adding your list items. Should I trim the rest, or leave everything.

Actually, I'm wondering if you were referring to the correct post. I had two posts earlier. The first was the samples for a C138, C133 and C135.

The second was to point out a discrepancy in the LA mksol ETAs.

Do any of the interested parties watch this thread for this type of info, or should I try to post to the CADO-NFS project?

I see the composite size now, that's an excellent way to encode it.
I don't know what is valuable for other people; the timings in the summary are all that's really needed to evaluate the params for a composite.

I realize these have duplication, but I haven't figured out how to automatically remove duplicate lines, yet.

Anyway, Is all the info you need contained in the following three samples?

C86, C129, C121:

Code:

Sure, looks like enough to make some observations.

On your C129, sieve time was 120ksec, while bwc was 24ksec; in wall clock time, bwc was 6200 of your 10600 sec job.

On your C121, sieve time 53ksec, bwc 5300 sec; in wall clock time, bwc was 1300 of your 3000 sec job.

So, the C121 was over-sieved enough to make bwc time 1/10th of sieve time, resulting in a substantial savings in wall clock time.

The files I posted target bwc time to be 1/6th to 1/5th of sieving time; I think your C121 shows the way for your setup at bwc time = 1/10th of sieving time. Factoring a C120 in under an hour is pretty snazzy.

I also like the C138 in just over 4.5 hours, although I think my CADO/msieve hybrid would do better, which is what's driving my interest in your params and the mpi bwc.

Anyway, here is a file of data for 87 runs ranging from 74 through 138 dd. It does include all previous samples. These are with unmodified params files from the original developmental version from a few days ago:

I'm running a "last" test of new C120 and C130 files; if results fit the time-vs-size curve I expect, I'll have them posted in the morning for you to the params thread. C125 is still a little slower than the curve suggests should be possible, I still have some tweaking to try there to get a bit more speed.

Default The Last Four Unmodified Runs

I have installed all your modified params files from the other thread. These are the last four unmodified that ran. Of course, I realize that not all of the params files in my current set are modified, but I'm considering the next sets as Modified:

Default Of All the STUPID Things I've Done!!

I accidentally wiped out all my scripts that ran my Aliquot Sequences on my controlling machine - the ones that communicated with the db and ran the ecm and nfs scripts!

The nfs script itself was untouched and I've found an earlier backup for the main controlling script, which is quite fortunate, since I remember having to solve several issues and I have no recollection of how I did solve them. I would have had to research and relearn a bunch. Still, reconstructing all the other scripts may be time consuming, so it might be a while before I get any more data compiled and uploaded.

BTW, in case you're interested, I used a recovery program to try to bring them back, but was only able to get the filenames, which unfortunately overwrote the original "deleted" files with zero-byte replacements.

Default Back Factoring...

I have the scripts pretty much rewritten and they are "mostly" working correctly.

Here is a file of Info for 91 composites factored using VBCurtis' params files, where available. (There may be duplicate runs for some of the numbers.)
