C201_3366_2226 has built a matrix 43M at TD 120.
It'll take 56 weeks to solve.

A series of random reboots prompted me to try to figure out the instability; since there were a dozen or so reboots while the matrix was running, I have low confidence in the correctness of the 40%complete calculation. So, rather than try to get a 4channel 4x4 + 2x8 = 32GB configuration working, I'm going to move the data to another machine and start the matrix over. The other machine is a bit slower, so it'll be 6 weeks (hopefully?) from now for factors.

I accept! Go for it. I'll shift to poly select on the c220 from Aliquot 4788.

AS 3366:i2233
I have finished test sieving the AS job C201_3366_2233. I even tried varying rlim/alim to 200M/250M and 250M/200M but the parameters listed below worked best.
Code:

Q(M) Yield # of spec_Q Corrected Yield 50 28685 556 29103 100 31706 534 32233 150 32209 536 31919 200 34102 555 32147 250 31112 519 31001 300 33201 575 29581 350 29045 526 28068 850M relations? Less? 850M relations equates to a Qrange of 50325M. Also the yield > 3.0 for much of the sieving range and is arguably too high, but the ideal of running a GNFS 201 job at lpba/r = 32 was not appealing. Open to any suggested improvements.

I'd guess 875900M relations to get a nice matrix; perhaps 50330M and try filtering before deciding how many more Q?
Yield of almost3.0 sounds quite nice!
