A blog about making HPC things (kind of) workDid you know, the typical HPC node has a bunch of programs running in addition to the users application? Have you ever wondered what these are and what they are doing or if they are needed?Most of the programs are service daemons or things that run in the background. For instance, the web server httpd daemon waits for input on port 80 and then tries to deliver a web page based on the request. Of course, there is no need for a webserver to run on an HPC cluster node.
