Mark,
I'd start with OpenHPC on linux. They provide well-tested recipes with
multiple software options and make the whole thing pretty easy.
I'd use slurm for the scheduler (a single hetergeneous cluster) and the
various other bundled OpenHPC components to manage nodes and so forth.
We do this for both small and medium clusters and it works well. We
chose centos 7/warewulf/slurm as our track.
Regards,
Bill

I'm getting into the game again as a private individual. When I was
active Opteron was just launched - I was an early adopter of amd64
because I needed the RAM (maybe more accurately I needed to thoroughly
thrash my swap drives). I never needed any cluster management software
with my 3 node, dual socket, single core little baby Beowulf. (My
planned domain is computational chemistry and I'm hoping to get to a
point where I can do ab initio catalyst surface reaction modeling of
small molecules (not biomolecules).)
I'm planning to add a few nodes and it will end up being fairly
heterogenous. My initial plan is to add two or three multi-socket,
multi-core nodes as well as a 48 port gigabit switch. How should I
assess whether to have one big heterogenous cluster vs. two smaller
quasi-homogenous clusters?
Will it be worthwhile to learn a cluster management software? If so,
suggestions?
Should I consider Solaris or illumos? I do plan on using ZFS,
especially for the data node, but I want as much redundancy as I can
get, since I'm going to be using used hardware. Will the fancy Solaris
cluster tools be useful?
Also, once I get running, while I'm getting current with theory and
software may I inquire here about taking on a small, low priority
academic project to make sure the cluster side is working good?
Thank you all for still being here!
