Welcome, and remember:

Every cluster is good.
If a cluster is wasted,

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
