Yes, according to CADO manual A can be used to fine-tune that parameter. So for integer values of I (or odd values of A) it doesn't matter which one is used?

Alright, thanks. The tasks.sieve.adjust_strategy = 2, is there a general rule if it's useful for SNFS or not? And if I was to test and change this back to 0, I should probably also revert to tasks.I?...

Then that might be a big part of the problem, I didn't include it in the params file.


Other than that, I don't remember the exact point of this increase but it was quite sudden. I found a...

Btw, I had 75% uniques with the c135 params for one number, I think this is relatively high? It's good, but maybe it still gives a hint what could be optimized?

So having an SNFS-177 take as long as a GNFS-139 really seems a bit long? I thought it might be due to the large coeffcient but the steep increase surprised me.

I was using these (slightly...

Ok, thanks everyone. The sieving times for 1281979*2^n+1 suddenly increased strongly from about 5 h at n = 578 to 9 h for n = 590. In terms of time that places the SNFS-174 as a GNFS-135 while the...

Ah, thanks. Is there any good advice on which q-ranges to test? If the dependence of relation yield to q is linear, just the beginning and end should suffice, is it like that?

How to test-sieve

How is test sieving done with CADO? I thought to just start it normally and have it sieve for a defined time or percentage, but that doesn't measure how strongly yield will decrease at larger q. How...
