to me the goal of having 'ps' show everything in the cluster is kind of cute at best.

but yes, right now you install all kinds of services and support nodes, and distributed filesystems, and orchestration tools and software management tools and job schedulers. every cluster is a bespoke mess that takes a large staff to maintain and is always broken.

this is kind of the projection of web software onto hpc clusters.

in the 90s it wasn't nearly as hard to run a supercomputer because it was an integrated software platform. they were still a lot dodgier than the needed to be. but you could run a 64k node system with one support person, and there weren't really very many support tickets because things just mostly worked.

but I certainly can't imagine trying to do a company that solves this problem. or I should say I keep trying to and just seeing failure. part of the issue is that the people that you are selling to are personally and monetarily invested in the status quo. I don't think they _want_ to relieved of the burden of messing around with Kubernetes all the time, and having distributed filesystems that need to be nursed all the time, or having provisioning tools that have a 80% success rate and take hours to spin up a node.
