No,sr2sieve has a -t option to run multiple threads. With that option you can just use one instance/folder/command and still use the 4 cores of a quad. Normally this is slower than running 4 instances,but when the sievefile is big,it can be faster.

Really? Hmm...I didn't know multithreading could be faster with a big sieve file.

The "care package" that I put together to get David started yesterday runs multiple instances using the -u switch--there are eight batch files in the sr2sieve folder, each with 1/8 of the total range.

3. I am planning on all of my ranges being done on Jan. 16th. If you can shoot for that date on your reserved ranges, that would be helpful.
It'll be tight for me but I think I'll sneak in just at the wire (assuming no glitches). As I say that, one of my quads doing the sieving just re-booted all by itself.

If you're in by Jan. 20th, we're good. Thanks for helping!

Just a note: I am still assuming that you will be done with the P=1.4T-1.8T range here in the next day or two, which is what I think you had previously said. Is that correct?

I'll get the n=50K-200K portion of the 9th drive started when you're done.


Thanks,
Gary

I have now removed P=1.4T-1.8T factors from the file link in the 1st post of this thread. 80000+ factors total.

My sieving for P=1.8T-3.4T should be done by morning so I'll have a lot more factors to remove at that point.

Would it be a problem in processing my factors if I drop that new file into my sieving to speed it up? Also I recall that the file can be dropped in over the old one without having to restart sr2sieve, is that right or am I mistaken?
