[QUOTE=Joshua2;202511]so it was missing carriage return. I edited my previous post to have all the latest wc lines 58130798. how many relations we need? if I filter once will it have to refilter stage 1 again or i need to wait?[/QUOTE]

Go ahead and filter, but we're nowhere near the number of relations for a matrix. Once the relations are all in, you'll have to filter again, but that won't take more than a couple of hours.

Filtering now will give you a picture of how close you are to a matrix, in terms of unique relations, and number of relations vs. number of ideals.

Looks like you got all posted files downloaded, but...
You included a .tar and a couple duplicate files in your latest merging. I'm counting that you should have 57228329 relations, which is what your total would be (within one or two) without the files I bolded.
Msieve shouldn't really blow up, (I just tried out similar files, and it's quite silent about the whole thing...just a couple unreadable lines from the .tar formatting; now if it were a compression and not simply an archive, like .bz2 or .zip instead of .tar, it would be unable to read that part of the file and so complain with many errors) but it is throwing off your line count a bit. You can rebuild the .dat completely or not, whatever you want.
[quote=Joshua2;202511]how many relations we need?[/quote]
I don't really know, but 10metreh said we should sieve 20M-120M. You've only got the relations from approximately 20M-70M.
[quote=Joshua2;202511]if I filter once will it have to refilter stage 1 again or i need to wait?[/quote]
It will have to do all filtering again. There is no real benefit to filtering yet, besides checking that everything's set up right and there are no major problems with any necessary files.
If you know enough about what msieve is telling you to know how close you are to a matrix, then you can learn that from it. (as FactorEyes said)

Not there, yet
 
[CODE]begin with 47682934 relations and 60169029 unique ideals[/CODE]

This looks about right - you're halfway there, as far as raw relations.

Once the remaining 50% of relations come in, you'll have around 85-90 million unique relations and somewhere between 70 and 80 million ideals, which will give you a matrix.

Not even close :smile:

Andi47 2010-01-20 07:46

67-70 is ~80% done, ~2.7M relations so far.

[/code](the last 4 lines are new)[/QUOTE]
Those last 4 lines are not necessary for postprocessing.

As was mentioned before, there must be a newline at the end of each line, or it won't be read correctly. Which text editor failed to write the last newline?

Yeah, I noticed. Hence my edit. :smile: I thought about taking out what I posted that was wrong, but never did.

Most likely, the text editor was just doing what it was told. If you didn't copy it in a way that included the newline at the end, (and didn't put it there yourself) then it doesn't know there should be a newline at the end, and it won't write a newline at the end. In any case, shouldn't msieve be able to read it even without the final newline? (just to not avoid the question: I used Metapad. I don't know what Joshua2 used, but I'd guess it's a pretty common occurrence.)

I used notepad, most people with windows would use that prob

This is an issue I really have to keep track of here, using both winXP and linux machines. For the linux ones, I need to ensure there isn't anything extra, while the winXP needs an extra CR/LF. If I mess up in either direction the particular machine scolds me.:smile:
