Speaking of efficiency, it is much better to flip the order of the loops. Exponentiation and the other operations on big numbers are a lot more expensive than division by a single limb, so do the...

The compiler should know to cast 0 and 1 hardcoded constants into the appropriate size (char). The problem is that the primes array is being overrun by this line:

for (i=0;i<=sieve_depth;i++)

The estimated total sieving time looks like it isn't being printed correctly, but other than that it all looks fine and the best poly was chosen. Note that this number isn't 5 digits larger, it is...

Is the C160 a quartic, by chance? The degree of the polynomial matters and degree 4 for a C213 is suboptimal. Unfortunately this is the only way to make a SNFS poly, sometimes. It's better than...

If you use *only* msieve, then by far yes, because msieve does not have a lattice siever. Which is why everyone uses either CADO, or some combination of msieve and ggnfs. msieve does the polynomial...

Several people have asked about yafu on the M1. You are right that it is ARM based. Unfortunately yafu 2.0 only runs on x86-64, as of now. I think only minor changes would be required to make it...

In theory, no, but plenty of weird stuff might happen with inputs near or larger than 1024 digits. Not a corner of the code I test very well.

There is no built-in limit. There is nothing computationally intensive about processing them. So, have a ball! If it helps at all the structure of them is:

Yes that does make sense :smile:.

There is also the existing "inmem" option. As the name suggests, siqs does all work in RAM and never writes to siqs.dat. Of course if something goes wrong or...
