I think I can use some help...
I only have one core free to chime in.

I opt for the file on friday, and then distribute the load between us (or more people) to get to concluding the drive sooner.

Or I could send you a file sieved to P=60G on Friday. Let me know which you'd prefer. My estimate of the optimum sieve depth for breaking off n=50K-75K would be around P=150-175G but it could be lower...around P=120-130G. The optimum is not going to come in much higher than the optimum for n=25K-50K (P=100G) because there are going to be many less k's remaining. Do you want to sieve from P=60G to P=~150G-175G yourself or do you need help? I assume you know to use srsieve for sieving. If you use more than one core, be sure and use the -f switch for all instances so that it will write out factors for all of them for later removal. Gary

OK, I'll send you the file sieved to P=60G on Friday. My 2 cores are kind of slow; 32-bit operating system; but still sufficient for this small effort.

If you want to sieve P=60G-100G, I'll sieve P=100G-150G or whatever optimal turns out to be. If it needs to be sieved further, we can coordinate at that point.

I can sieve P=~20G per day so my 50G range would take 2-3 days, which would put it done to P=150G sometime on Monday.

Carlos,

Thanks for helping and posting some primes now.

Micha,

Whatever k's Carlos finds primes for, I'll remove from the sieve file before sending to you on Friday. He said it'd be ~24 hours to complete his range so that timing would work out well.

Great. My sieving to P=60G should complete by this time tomorrow plus ~2 hours, i.e. ~26 hours from now. So we'll have a nice efficient file to sieve for P>60G.
