Don't worry, I'll still post-process it. Just don't forget to send me by PM the link to download the relations file.

OK, I'll start testing for a matrix at about 75M and let you know. I'm still going to try to find out if my cluster could handle it and what ETA it would give me. I would like to see how it compares to yours. If it says it would wok and it's not that far off, I'll let you decide which of us finishes it. Thanks.

 2016-10-10, 00:52 #322 EdH     "Ed Hall" Dec 2009 Adirondack Mtns 3,617 Posts Well, I have enough relations for a matrix according to msieve, at a little under 50M. My trouble is that I can't get any file hosting service to accept anything of size. I'm currently trying to get sendspace to accept them, but at 150KB/s, it'll be tomorrow before I can get "all the little pieces" up on line. And, yes, I compressed them. I used split to make smaller parts - cat can sew them back together. I .zipped each one and am trying to upload them to sendspace. I tried some other file hosting places, but nothing else worked. On the bright side, if I let my cluster do it, it says ~59 hours. Might be sooner than it will take to transfer the relations and start another machine. Thoughts? After-thought: Maybe I should have been sending groups of raw relations all along, rather than waiting to compile a file of unique relations...

What's the size of your files? drive.google.com offers 15 GB of free space for example.

My total file is about 2.7G compressed. I also tried breaking it into 2, 4, 8 pieces. But, all the sites that said they would accept it, either wouldn't at all or had some error page show up. I finally went with sendspace, which I have used in the past, but they insist on uploads of less than 300M.

Thanks...

Thanks Carlos,

I should have the factors on Wednesday morning from my cluster. I'll do some research and come up with a better method for next time. Even if I found a good place to put them, my upload speed isn't all that great, so it would still be quite a while before they would be available.

Take Care,
Ed

 2016-10-10, 15:31 #329 pinhodecarlos     "Carlos Pinho" Oct 2011 Milton Keynes, UK 5·7·139 Posts Ed, Are the fb and ini files on the zipped files? EDIT: do you know how many unique relations do you have so I can guess which target density to use on msieve? EDIT2: Missing downloads should be completed within 1 hour. Then I guess in 1h30 I will have an ETA for the LA. Last fiddled with by pinhodecarlos on 2016-10-10 at 15:48
