<p>Another one of us! I got a rush just then when I seen the figures
5-30 servers in collections and then looked at my home built rig.</p>

<p>*Yes, you belong here, sorry I'm rammed with work currently! But
you are very welcome and over the period of my membership I've
been helped many times, even offered an open invite to come and
visit a proper professional HPC data centre too of which soon I
might hope to take them up on the offer if it still stands.<br>
You'll meet some very knowledgeable folks here, Welcome any time!</p>
<p>Kind regards,</p>

<p>P.S: If you spot any drink or drugs in the images, I never posted
them.. Right?? (but want them back) I'm only kidding! Honestly!<br>

<p class="MsoNormal">Hi folks,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I thought I’d give a brief
introduction, and see if this list is a good fit for my
questions that I have about my HPC-“ish”
infrastructure...</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am a ~30yr sysadmin
(“jack-of-all-trades” type), completely self-taught
(B.A. is in English, that’s why I’m a sysadmin :-P) and
have ended up working at an industrial research lab for
a large multi-national IT company (<a
href="http://www.nec-labs.com" target="_blank"
moz-do-not-send="true">http://www.nec-labs.com</a>).
In our lab we have many research groups (as detailed on
the aforementioned website) and a few of them are now
using “HPC” technologies like Slurm, and I’ve become the
lead admin for these groups. Having no prior background
in this realm, I’m learning as fast as I can go :) </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Our “clusters” are collections of
5-30 servers, all collections bought over years and
therefore heterogeneous hardware, all with
locally-installed OS (i.e. not trad head-node with
PXE-booted diskless minions) which is as carefully
controlled as I can make it via standard OS install via
Cobbler templates, and then further configured via
config management (we use Ansible.) Networking is basic
10GbE between nodes (we do have Infiniband availability
on one cluster, but it’s fell into disuse now since the
project that has required it has ended.) Storage is one
or more traditional NFS servers (some use ZFS, some
not.) We have within the past few years adopted Slurm
WLM for a job-scheduling system on top of these
collections, and now are up to three different Slurm
clusters, with I believe a fourth on the way.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">My first question for this list is
basically “do I belong here?” I feel there’s a lot of
HPC concepts it would be good for me to learn, so as I
can improve the various research group’s computing
environments, but not sure if this list is for much
larger “true HPC” environments, or would be a good fit
for a “HPC n00b” like me...</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks for reading, and let me know
your opinions :)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Best,</p>
<p class="MsoNormal">Will</p>
