Yes.  I use all of the default settings to ssh-keygen and the default for
number of rounds is 100.

The exact commands used for the single threaded version are here:
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/moduli-gen/

As previously mentioned I have a wrapper script to split up work over
multiple processors but it only adds -J/-j flags for "start here" and
"process this many" which I run over multiple machines.  I will tidy up
this script and publish that too when I get a chance.

Once I have the complete list assembled I re-screen it on OpenBSD and make
sure the output agrees (other than the timestamp).  I would be happy to add
a verification by an independent software implementation (for practical
purposes it'd probably need to be free-as-in-speech; it sounds like ecpp-dj
might be a candidate).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
