 2022-09-25, 12:08 #875 gd_barnes     May 2007 Kansas; USA 23·5·172 Posts 51^99 terminates 349^57 terminates 51^99 is the first termination as a result of the index 1 effort. As of a day ago, there were 15 same-parity changes as a result of that effort. I've worked on all of them and 3 of them are interesting: The one above and these two: 21^121: 142/135/3; I'm working on. 24^118: 163/163/(none); No known factor at t45! Ed, are you interested in taking a hack at the C163? :-)

It interests me, but my GPU machine is corrupting its drive continuously. I can't tell if it's the drive or the computer. mprime runs fine for hours. Swapping drives is an option, but it includes other work needed reinstalling all the packages to match the hardware.

The GPU would run LA on the c163 in about 1.5 hours, while the CPU machine would take about 6.

I guess I've gotten "spoiled" running this GPU.

I'm still working on 347^61. 347 currently has 2 remaining. I'm done with 349. It has 3 remaining. I haven't previously taken on a C145 but I might take on 349^61 at 150/145/193/full later on. Other things are in the pipe right now. I'm also working on 780^52 for new base 780. I'm taking on the C141. The 4 sequences above that are tough. Jean-Luc did a lot of work on it. I would have done this one anyway since it's a new base but it was also on the index 1 list so it should be the 3rd termination from that effort. Last fiddled with by gd_barnes on 2022-09-26 at 11:25

I've also got to modify my current script. It worked a sequence that was already past index 1 last night, that it didn't need to.

Clarification: Was it already at index >= 2 when you started working on it or did it start at index 1 and then continue working on past it?

I'm asking because when I noticed you'd split one of those same-parity C138-139-140's, I'd fairly quickly run it through my usual process. So if it was the latter of the two above, it could have been my work on it past index 1.

 2022-09-26, 12:52 #880 EdH     "Ed Hall" Dec 2009 Adirondack Mtns 5·1,021 Posts Actually, I was mistaken (yet again). I thought I was working in the c130s and I have made it into the c140s. I will reset and see where I'm at after my update.
