I had missed something earlier. The very first line I get is:
Code:
Applying tune_info entry for LINUX64 -        Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz
Then it shows the following messages. This is a second nearly identical machine to the previous one:
Code:
$ ./yafu
Applying tune_info entry for LINUX64 -        Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz


YAFU Version 2.07
Built with GCC 9
Using GMP-ECM 7.0.5-dev, Powered by GMP 6.2.1

Detected L1 = 32768 bytes, L2 = 15728640 bytes, CL = 64 bytes

Here are the last few lines of the tune operation:
Code:
nfs: estimated time for complete factorization = 31033.7059 seconds
best linear fit is ln(y) = 0.101147 * x + -0.891959
R^2 = 0.967072
best exponential fit is y = 0.409852 * exp(0.101147 * x)
QS/NFS crossover occurs at 100.3 digits
found OS = LINUX64 and CPU = Intel(R) Xeon(R) Gold 5122 CPU @ 3.60GHz in tune_info field
Adding tune_info entry for LINUX64 -        Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz


***factors found***


ans = 0
and the last few of the new yafu.ini:
Code:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Tune options
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% If you run tune(), some information about the results should
% appear below here


tune_info=Intel(R) Xeon(R) Gold 5122 CPU @ 3.60GHz,LINUX64,1.59078e-05,0.196092,0.299688,0.0999245,102.36,42
tune_info=       Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz,LINUX64,2.60097e-05,0.197536,0.409852,0.101147,100.272,42
No editing has been done to the yafu.ini file after running tune. The only editing prior, was threads and paths for ggnfs and ECM.

This entire message was constructed via gedit without editing anything via the board's tools.
