My sieving range of P=1T-4T is complete. Unfortunately I don't have time right now to combine all the factors, remove them from the sieve file, and start another sieving range right now so I'm running my 3 quads on port G8000 for a day or so until I have time to get it taken care of.

A new file will all factors removed up to P=4000G (4T) has been Emailed to everyone.

Reserving P=6250G-9250G. My machines will start on it later today.

Ranges i have already reserved will be finished today.
I'll get them emailed to Gary tonight.

I will then sieve 9250G - 10T. Using the new file sieved to 4T

Per Email received from Brian, his ranges are now complete.

Brian, can you give us an ETA on your new range?

P=6250G-9250G is complete. Factors sent to myself.

Reserving P=12500G-15000G. ETA is March 30th.

I'll continue sievng P=250G per core so will pull a couple of cores off to put on port 5000 for a while.

At P=15000G (15T), that will be a sufficient depth for n=500K-600K, so we can start a new drive for k=1400-2000 for n=500K-1M with just that range to start with (after the 8th drive is done). We could also run a rally or two on the new drive to spike a large # of top-5000 primes and possibly attract some more new folks to our effort. :smile: (Note: Peter Benson has indicated that he will continue with k=1000-1400 past n=600K.)

Once I have all of the factors up to P=10T, I'll remove them from the file, Email everyone the updated file, and compute an optimum sieve depth for the entire range. We'll leave n=500K-600K in there since continuing to sieve it will save time on future double-checking.
