[QUOTE=Dubslow;327432]If I may, I would recommend [URL="http://filesmelt.com/"]filesmelt.com[/URL] for any more of these transfers. It's completely free, and more importantly, is free of any intrusive ads, doesn't have any bandwidth restrictions, doesn't try to sign you up with your credit card, and doesn't force you to wait 60 seconds to begin the download (and you don't have to press like four buttons).

Edit: Easy way to split up the file into multiple chunks: `more +<1> <filename> | head -<2>`, where <1> is the beginning line number, and <2> is how many lines. So to split up a 1000 line file into 4 chunks, you'd do
[code]for num in 1 251 501 751; do
echo $num
more +$num <filename> | head -250 > <filename>.$num
done[/code] (or something similar).[/QUOTE]
Even easier, and works for aribtrary values of 1000:
[code]split -l 250 <filename>
[/code] if you want an arbitrary number of at most 250-line files or
[code]split -n 4 <filename>[/code] if you want precisely four output files.

I've attached modified msieve MPI polynomial selection patch so you guys wouldn't have to manually split the input files.

jasonp, can you post links to all the batches left?

jasonp 2013-02-04 12:22

Okay, everything is up (I apparently don't have the upload capacity to be a good pirate :)

poily 2013-02-04 13:09

I took batch 7.

Taking batch 8 as well, I'll try to run it on 8 cores of FX-8150.

Ah, gracias! The old "post something bad enough to be corrected" trick has worked again! :smile: (It wasn't deliberate though :razz:)

Nobody took batch 6 yet.just saying it.

and for MinGW32, the line is
[code]
split -b 100m msieve.dat.m
[/code]
to split the file in 100Mb chunk

Just a warning, I plan to upload another batch of 6 million or so stage 1 hits around the end of the week.

That should be fine. I should be done with my two by then, and can pick up Batch 6, plus this new one.

Me too :razz: (my first batch will finish Tuesday to Wednesday overnight). Can we perhaps split 6 and his weekend dump?

Dubslow 2013-02-06 05:04

My batch has finished. Not having heard anything, I started the root sieve... if that finishes too, then I'll grab batch 6.

Edit: In some 20 minutes, I'm seeing 1e-19 with a scattering north of 2e-19. Not particularly impressive, though I am running the full 5000 so... who knows. What's their current best? Is the target still 2e-18?
