C201_3366_2226 has built a matrix 43M at TD 120.
It'll take 5-6 weeks to solve.

The 48GB machine solving this had a memory stick go bad. It was 4x4GB and 4x8GB, and one of the 8's failed. It's stable with 4x4 installed, but that's not enough memory to solve the matrix.

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 4-channel 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.

If it's more convenient for you, I can finish this one off. Just let me know.

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

Default 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:
n: 131059381160969890473184300494609882864431978456309837392557442177052630795870868382351497139096300267026719895523089453234540027837272339241326353564822104741922921032481193771448768282517397405699723

rlim: 225000000
alim: 225000000
lpbr: 33
lpba: 33
mfbr: 66
mfba: 96
rlambda: 2.8
alambda: 3.6

Test sieving on the algebraic side with Q in blocks of 10k:
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
I will admit to some uncertainty as to how many raw relations to generate. In the past with 16f/33 I would aim for ~930M raw relations, but perhaps a lower value of relations might be a better. Allows us to avoid oversieving and we can always add some more to the Q range if needed.

850M relations? Less? 850M relations equates to a Q-range of 50-325M.

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 875-900M relations to get a nice matrix; perhaps 50-330M and try filtering before deciding how many more Q?

Yield of almost-3.0 sounds quite nice!
