I use Scientific Linux these days. The differences between Scientific and
CentOS are trivial for these purposes. CentOS went into near-melt-down when
RHEL 6 came out. Scientific, with "real" funding, didn't. And, for me,
there are some additional benefits to Scientific. However, the real
differences are not worth any more discussion, and either will work with
Gempak. Or AWIPS-II. Various Solaris variants will also work, as Robert can
attest.
VNC will work. Friends don't let friends, or enemies, install TeamViewer.
I've extensive recent experience trying to get a Gempak install up with TV
and if I NEVER see that software again, it'll be too soon. It's slow,
temperamental and not ready for prime time. It's Windows code forced to
work "with" linux. VNC, sure. TV? NEVER. Did I mention I really don't like
TeamViewer?
For AWIPS-II, plan on one mega-machine, or 2-3 smaller ones. I'm
experimenting with a VM installation, with 3 VMs, mimicking National
Centers installations, each with 16 GB RAM. And, this doesn't include CAVE.
Hope this helps some.

That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.”
