Thanks for the information! I'll probably go Scientific Linux as well.
Any specific version I should shoot for or is any of them good?
I could probably get by on wgeting the data or running a little LDM.
Does anyone have the instructions for it? I can roll GEMPAK as an
installation OK, but I've never been able to figure out how to get data
going.
Side question, instead of VNC, could I SSH into the machine from another
Linux machine and run the scripts that way? That may allow me to run the
actual graphical stuff on my big machine, but serving right off the
other machine. I could SSH it remotely as well if need be.
Thanks!

Subject: Re: [gembud] GEMPAK and AWIPS II Questions
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.

Nathan,
8G of RAM isn't much if you are going to be ingesting a lot of data with
LDM and running GEMPAK decoders/scripts. If you are going to just
wget or
cURL model data from NCEP and not run an LDM with a big queue then
it would
likely be OK.
I'd go with CentOS myself. I am not a huge fan of Linux (I am a Solaris
guy) but where I have to use Linux I use CentOS and I have been real
happy
with it. Plus since it is Redhat based you will be good to go on
AWIPS II
which at this time will only run on CentOS/Redhat.
I'd go with 32-bit as AWIPS II isn't 64-bit (unless something has
changed
recently).
I am not familiar with TeamViewer but VNC works OK with GEMPAK assuming
you on inhouse modern Gigabit network. However you are going to find
that
doing big radar or satellite loops or displaying big gridded data
sets is
going to be pretty slow. Even on a box with a decent graphics card and
local monitor Solaris and Linux can be slow if you are using the
standard
Xorg drivers instead of say the Nvidia commercial drivers.
I don't think there is anyway AWIPS II will work well with 8GB of
RAM..and
Unidata lists 16GB as recommended. Remember it is Java based, so I think
16GB isn't going to be enough either (I know Unidata disagrees with the
statement)..
This mailing list (gembud) is very helpful to folks starting out with
GEMPAK so I am sure you can get tons of help.
Hope this was of some help. The vast majority of folks on this list are
Linux devotees so they can help you out more there..

Subject: [gembud] GEMPAK and AWIPS II Questions
Hi everyone,
I'm wanting to roll another GEMPAK installation, as well as possibly
install AWIPS II once available. I have a few questions though before I
get started.
I have an extra low power quad core machine outfitted with 8GB of RAM
lying around (I'd just need to pop in a hard drive and boot up).
1. What would be the ideal version of Linux to throw on it? CentOS or
Scientific Linux? Which version number should I shoot for, and should I
go x86 or x64? It is a x64 capable processor.
2. I don't have a great monitor for this machine for Analysis purposes
(just a VGA cheapy from Walmart, my big $1k LED monitor isn't compatible
with the machine). After the initial installation, can I run the machine
headless and VNC to it over the network? Could I also install TeamViewer
on it and remote into it as well?
3. Could someone here assist me in getting data to work in GEMPAK so I
can get the most out of using it?
4. Once AWIPS II comes out, could I upgrade to AWIPS II in place OK over
8GB of RAM or do I need 16 on the data server? I have another machine
running Ubuntu (with 16GB of RAM on it), and if I could install the
client there and connect to the AWIPS II server running 8GB, I'd be OK.
Thanks!

ssh -X into the machine and make sure X is allowed.
I am using SL 6.x, works good.
LDM is too easy to set up (although there are some gotchas) to not use.
Basically, stop thinking about how to do the install and slavishly follow
the LDM installation instructions. Leave your brain at the door; the
instructions were written to allow ANYONE to get it going. There are some
things to look at in the pqact.conf file, but better still, use the one
Gempak creates for you.
