Re: $smp, $p2p,... parallel options for Firefly 8

Hi Pablo,

sorry for the delayed reply.

The options you are asking for are now turned on by default.

The documentation on P2P is still correct, the only difference
is that the defaults now are:

$p2p p2p=.true. dlb=.true. $end

The documentation on the updated $smp group is now in the process
of preparation. However, typically you do not need to change
the default values using Firefly 8.0.0.

Kind regards,
Alex Granovsky
