I've reworked a bunch of my scripts and now I'm able to update both of these threads and my full local set of sequences without showing any activity toward my db limits. I still need to make some changes to my local set update script, though, due to the few .elfs that aren't supported by the db. I've got a couple options I'm looking at. I have correct .elfs for the sequences, but if I retrieve the one from the db, it overwrites the valid one with an empty file For this sub-project, I simply have it write an error message in my listing when it finds the file is empty, but for my updates, if the file is downloaded directly, the original is lost, so I'll have to address this differently. There aren't many, but enough to be annoying.

 2022-10-10, 09:50 #927 gd_barnes     "Gary" May 2007 Overland Park, KS 2E3F16 Posts 888^56 terminates Its a new base but it was originally in the index 1 effort. That makes 14 terminations there. I won't be on until later today so here is an update to the last status post: 347^63: 149/147/109/full; released 307^63: 140/137/3/full; still working; ECM will not split any of its C120s-130s; 2+ days now 1155^51: terminated per last post I'm done with new base 1264460. Base 888: Still working on ^50, ^52, & ^54. 888^50 turned tough quickly. At 147/143/3/full it will tie a personal largest factoring effort. That plus the small factor 3 will tie up the Ryzen for ~1-2 days. I'm a little extra motivated to take it down. Its starting size of only 148 is far smaller than the 154-digit standard we set a few months ago. The good news is that if all of the above exponents can be terminated, then all sequences < 170 digits will be complete for base 888. ^54 & ^56 are actually much easier than ^50 & ^52.

I'm done with it. I'm now working on 347^63, 373^65, and 1184^54. I noticed that 367^65 from your Oct. 8th post has not been split. I won't object if you skip that one. :-) Last fiddled with by gd_barnes on 2022-10-11 at 03:25

Interesting! You are, of course, correct. Here is my list of completed single runs for that list to now (with end states):
Code:
373^63 (160/152)
367^63 (159/156)
347^63 (150/144)
359^63 (154/152)
373^65 (159/157)
347^63 (147/146)
1184^54 (146/144)
22^123 (166/162)
I'll put it back in the queue again, but I'm currently running with fewer of my machines by about a third. It will take a bit longer than normal.

I'm very confused by this post. In that list are two that I previously reported as terminated (347^63 & 359^63) and one that is an opposite-parity (22^123).

347^63 is listed twice.

Are you saying that you're putting the entire list back in the queue? Per my previous post I'm working on two of them.

I can only assume that you are stating that you will put only 367^65 back in the queue and that you are providing the list so that I can make sure that I run my typical usual process on all of them. That would make more sense.

367^65 is not really a good sequence to spend so much time on a C161, which is why I said I wouldn't object if you skipped it. There are 2 remaining for that base and its current size is 163 digits; not one I would be inclined to stick with.

Edit: After going down the list, I see that all of them are either terminated, in the works now, or were worked previously and released. Here is their current status:
Code:
373^63 160/152/3/t40 released
367^63 159/136/3/full released
347^63 terminated
359^63 terminated
373^65 143/137/5 working on
1184^54 134/125/3 working on
22^123 166/155/2/t35 released opposite parity; I ran some quick ECM on it and added a few indexes.
373^65 & 1184^54 have been long running but they have come down far enough now that I will take them to termination.

 2022-10-11, 21:42 #935 gd_barnes     "Gary" May 2007 Overland Park, KS 11,839 Posts From what I can tell, all previous splits from you are either in process by me or released so I'm now working on new bases 379 and 383; all same-parity exponents > 50.
