Wasn't Brucifer sieving this?

This is a range accidentally missed.

Ok. Good work!

Bruce is going on vacation and his machines are off now. Lennart is sieving from P=4920G-14T plus the accidentally missed range. Bruce had sieved to P=4920G minus the missed range.

Sieving will probably be needed up to P=20T-25T. At P=14T, we're going to pause, combine the k=300-400 range in with it, and compute optimum sieve depth. It will then be one big sieving effort for k=300-1001 that will also reduce the future LLRing time needed for the individual-k reservations, which were originally sieved on a 32-bit operating system.

Gary,

Post here the sieve file and start a reservation board. Quickly you'll have people helping you.

It is only 13T-14T done now I have 5T-7T 7T-9T 9T-11T and 11T-13T left they are 60% done and we have to wait for them.

Lennar,

With n up to 1M we need to go to P=30T or 40T but I suppose we will only do that to the range 900k<n<1M.

Why ?? If we sieve all range to 30T or 40T we save more time.
Sieving does not take much longer if we keep all n.

I think sieve deep should be around n=850k -900k LLR time
and if you need to doublecheck it would be 2*LLR time. :smile:

Hi Carlos,

Actually, that would be a little tougher than it would seem: the first and foremost problem being that the sieve file is really huge! :smile: If you (or anyone else, for that matter) would like to help out, though, please send Gary a PM/email--I'm sure he'll be glad to have you help. :smile:
