Thank you Peter. You did a huge amount of work! It's also a several hour effort to update everything from my perspective. I'll be making some time later today to start downloading and updating everything. Unfortunately sendspace has a 300 MB hourly and 1 GB daily download limit so I'll have to space out the updates over several days.

Gary-
I have one more 25k chunk to finish my part to 2500M; once I complete that in the next few weeks, I'll re-learn how to send you the relevant data. Then, I suppose, I can test out the limits of sr2sieve's ability to handle thousands of k's? I think it will be more efficient to sieve as many k's as possible over a smaller n-range than previous sieves (say, 50k for the first pass), but memory constraints may decide this for me.
With Peter's immense amount of work done, we're over 20% of the way to the conjectured k-value, right?

Oops
 

[QUOTE=Puzzle-Peter;343668]I just finished uploading the rest of my reservation to sendspace. As always, a download link has been sent to Gary.

This didn't run as smoothly as I had hoped. I'll have to investigate what caused the huge speed differences on - to the best of my knowledge - identical machines.

No new reservations for now.[/QUOTE]

Peter,

Unfortunately I did not get the range of k=9.6G-10.2G downloaded from Sendspace in time before the site deleted them. Can you upload them to Sendspace again?

Sorry about that.

Will you be finished testing k=2.05G-2.5G to at least n=25K?

When your range is complete to n=25K, we'll not quite be at 20%. We'll be at 11G / 63G = 17.5% of the conjecture complete to n=25K.

No problem. I'll re-upload them on them on monday.

I have started a sieve from 2.5G-9.6G to see if it works.

Gary-
I ran PFGW script to 15k instead of 25k; I'll sieve and test to 25k so that everything is consistent to everyone else's work.

I am taking 2.5G-9.6G up to 100k.

Can you provide some stats on that sieve? Specifically:
How many k's?
How many MB does sr2sieve take to run- or do you have to use srsieve?
How many k/n pairs are in the sieve at whatever depth you're at?

That's one big sieve.

I am only using srsieve.

I sieve 2.5G<k<9.6G 25k<n<100k in one file.

Then I cut out 0.5G and run it alone to get a range I can LLR to 100k

You can't use sr2sieve on 0.5G k's maybe later after 100k are done.

I shall see how many k's I can use in sr2sieve but I think that will make very small ranges and you may save some time with a lot more work. :)


The first range is not sieved very high, it's 2.5G-3G 25k<n<35k. 2787 k's They are soon done. It seems to end up in about 700 primes so I expect the range will have about 65% primes (25k-100k).
That will reduce the amount of k's and it will be easier to manage the base.

If you have any better ideas pse. share them :)

I use srsieve on a i7 2600k and I am only running 1 sieve using about 6G memory total on that computer. I have only 8GB on that computer. I think I will split it in 3 ranges and use 2 computers (3 ranges) later

Gary, did you get the email generated by sendspace?
