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.

*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.
You'll meet some very knowledgeable folks here, Welcome any time!
Kind regards,

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!

Hi folks,
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...
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 (http://www.nec-labs.com). 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 :)
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.
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...
Thanks for reading, and let me know your opinions :)
Best,
Will
