A couple more caveats: no native 64-bit images yet, interrupt throttling.

Also add names of machines to table of how-many-have-what-nics.

currently possible. We plan to upgrade our Linux and FreeBSD 5 images
to support SMP in the near future as well as address the 4.x SMP issue
for standard images.
<li> <b>The nodes run in 32-bit mode.</b>
The processors in these machines are the Intel EM64T Xeons, but we have
not yet created 64-bit native versions of FreeBSD, Linux or Windows.
<li> <b>The network interfaces use "interrupt throttling."</b>
The Intel Pro1000 cards used for the experimental interfaces in
these machines default to using interrupt throttling. This will
add latency to packet delivery and reception. See the

knowledge base entry</a> for how to change or disable this feature.
