Could you stop loading those candidates ?

How high is your files on s9 sieved ? I started sieve s9 from 2T-3T and it finds factors very fast.

edit:p=2058652664447, 126759224 p/sec, 6 factors, 5.9% done, 77 sec/factor

This is in a early stage of the sieving but wait some time then I get more info





Edit 2: p=2500616307971, 126432416 p/sec, 43 factors, 50.1% done, 92 sec/factor

I take this up to 12T now

Oh, that is bad. I did not realize that we had a sieve file that was so woefully undersieved on S9. It appears sieved to only P=2T (before Lennart started on it).

Everybody please hang tight while we get the servers upgraded and the file sieved to an appropriate depth. Do not do any testing on the file.

Max, it would be best if you delete all of the S9 candidates out of the server so that someone does not accidently start testing it.

I am un-sticking this thread until we are more ready with these efforts.

I will sieve more but I think you can start it now.

Edit I am sieving to 21T and it will be done today.
