I never used Bright. Touched it and talked to a salesperson at a
conference but I wasn't impressed.
Unpopular opinion: I don't see a point in using "cluster managers"
unless you have a very tiny cluster and zero Linux experience. These
are just Linux boxes with a couple applications (e.g. Slurm) running on
them. Nothing special. xcat/Warewulf/Scyld/Rocks just get in the way
more than they help IMO. They are mostly crappy wrappers around free
software (e.g. ISC's dhcpd) anyway. When they aren't it's proprietary
trash.
I install CentOS nodes and use
Salt/Chef/Puppet/Ansible/WhoCares/Whatever to plop down my configs and
software. This also means I'm not suck with "node images" and can
instead build everything as plain old text files (read: write SaltStack
states), update them at will, and push changes any time. My "base
image" is CentOS and I need no "baby's first cluster" HPC software to
install/PXEboot it. YMMV

Hi Beowulfers.
Does anyone have any experience with Bright Cluster Manager?
My boss has been looking into it, so I wanted to tap into the
collective HPC consciousness and see
what people think about it.
It appears to do node management, monitoring, and provisioning, so we
would still need a job scheduler like lsf, slurm,etc, as well. Is that
correct?
If you have experience with Bright, let me know. Feel free to contact
me off list or on.
