Here is where I see it going
1. Computer nodes with a base minimal generic Linux OS (with PR_SET_NO_NEW_PRIVS in kernel, added in 3.5) 2. A Scheduler (that supports containers) 3. Containers (Singularity mostly) All "provisioning" is moved to the container. There will be edge cases of course, but applications will be pulled down from a container repos and "just run" -- Doug > 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 > > > Jeff White > > On 05/01/2018 01:57 PM, Robert Taylor wrote: >> 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.
