Hello all. I am just entering the HPC Sales Engineering role, and
would like to focus my learning on the most relevant stuff. I have
searched near and far for a current survey of some sort listing
the top used “stacks”, but cannot seem to find one that is free.</blockquote>

<br>
Not really, although there's some overlap.<br>
<br>
Resource managers like Torque (PBS) are in charge of ... managing
the resources.<br>
<br>
Job schedulers (e.g. Maui, MOAB) decide which job gets to start
next, and talk to the resource manager (i.e. poll for available
resources, instruct which job should start next, etc.).<br>
