OBTW, Reserving 4000G to 6000G

No. I'm doing P=250G per core in 15-16 days (i.e. 1T per quad). You're doing P=500G per core in 74 days (i.e 2T on a quad). If it was the same speed as mine, it shoudl take you 30-32 days per core. Hold old is your quad. Although I'm using 2.4 Ghz Intel's, the AMD's should be nearly as fast for sieving. Are you running 64-bit sr2sieve on a 64-bit O.S.? Since it's an older AMD, I would almost exactly twice that speed, i.e. P=500G per core in 37 days.

Are you reserving 74 days work? If so, I'd prefer if people only reserve about 2 weeks worth of work at a time. I'm requesting that in case we have a "heavy player" come along who swoops up and is able to complete everything to P=~15T in 2-3 weeks. We don't straggling ranges holding us up at that point.

On another note, Chris, are you reserving any sieving work? I couldn't tell by your long commentary here.
