For Intel CPUs, max values are not about particular CPU but rather
about limitations of CPU's microarchitecture and design. They are
rather useless.

In most cases, you would like to run Firefly on this system
using -np 2 option as there are only 2 physical cores.
If you want to use all four logical cores, use -np 4 and edit your
input to add this instruction:
$smp httfix=.f. $end
Hope this helps.
Kind regards,
