[QUOTE=richs;309426]Paul, I did 7+6_266, 8-5_259 and 9+5_245. I emailed you the results for these on 15 August, 21 August and 7 August respectively.

Rich

I also did not factor 11+4_224 per your list.[/QUOTE]Thanks Rich. There's quite a bit of confusion as to who did what, how and when. With your help, and that of Rocke and Tom, I hope to get things sorted out over the next day or two.

I did get your mail. I can't work out why it wasn't processed properly though my incompetence would appear to have played a major role.

[QUOTE=xilman;309502]Thanks Rich. There's quite a bit of confusion as to who did what, how and when. With your help, and that of Rocke and Tom, I hope to get things sorted out over the next day or two.[/QUOTE]Tom has told me that he received the submission for 11+4,224 on 20120717 from person or persons unknown. I've taken a guess that it's by SNFS and the entry now reads [code]11+4 224 C183 39067650448279469971149402579560475766645324618608116682559309332697775687340028801. P101 ? ? SNFS 2012-07-17[/code]

AFAIK, the remainder of the data on the web page are correct.

I've been using Tom's reservation website for all the homogeneous Cunningham numbers that I have been working on. Thanks!

[QUOTE=xilman;309380] There are now 525 composites remaining to be completed and the ECM server at 207.192.74.4[B]8[/B]:8194 is allocating tasks with B1=43M. Jon Becker's client found a p52 earlier today.

[/QUOTE]

It's missing a number on the ECM server IP.

Thanks. A C&P error.

Paul, is the server down from your side? Lost contact to the server since yesterday at 8 PM GMT.

Seems fine here. As you can see, internal and external clients are connecting properly.

I'll check to see whether the Homogeneous Cunningham server is accessible.

Added in edit:

The machine had rebooted around 16 hours ago and the ecmserver hadn't restarted. It's not my machine so I tend not to see crashes, etc, until long after they occur. Anyway, it's restarted now.

pinhodecarlos 2012-09-01 16:05

Sorry, I though you would get it due to the post be on the GHC numbers thread but probably it was me who started wrong the phrase giving you the wrong impression to which ecmserver I was talking about. Anyway, already uploaded the curves. Thank you for kicking up the server.

[QUOTE=xilman;309380]There have been quite a few discoveries since I last posted an update almost three months ago. [/QUOTE]The last 6 weeks or so have seen quite a few new factors as in the list below. There are now 513 composites remaining. Surely it should be possible to reduce that to below 500 before the end of the year.

The ECMnet server is still allocating B1=43M tasks, suitable for find factors around 50 digits, but only Jon Becker seems to be working on them. He's doing sterling work but it would be nice if others joined in.
