Maybe your download failed. The file available at https://github.com/bbuhrow/yafu/blob...e/yafu-x64.exe is (currently) 2,582,528 bytes.

When I try to build yafu under Ubuntu with make NFS=1 USE_SSE41=1 USE_AVX=1 it quits with:

Omitting the USE_AVX2=1 flag, then it builds successfully.

I've got another of those "it won't factor it" jobbies in Yafu 2.08. For some reason it won't go into QS/SIQS.

Code:

I thought this was fixed.

The next stage for this number must to be GNFS

No, a C102 can easily be solved by QS. It's not the ideal method, but shouldn't be more than 2-3x slower than GNFS.

According to tune_info the crossover point is 112:
Code:
