Many thanks for all these precious information. The settings

-gnatnp -O2 -march=native -ffast-math -funroll-loops

was only 1 s faster (1537 s) as compared to using

-gnatVa -O3 -gnatn -funroll-loops -gnatf -gnato

which took 1538 s. I have two questions:

1. I see that you use -gnatnp. Is this safe to do so i.e. to suppress
all checks?

2. In the specification -march="machine architecture here", you use
native for the machine architecture. Does this apply to Intel
processors as well?


And thank you very much for making accessible the programs on your
website. This is indeed very generous on your part. I find some very
useful codes there.
