Dan, The requirement for varying CPU and RAM requirements sounds like it could be met with the Heterogeneous Jobs feature (https://slurm.schedmd.com/heterogeneous_jobs.html <https://slurm.schedmd.com/heterogeneous_jobs.html>) of Slurm. Take a look at that document and see if it meets your needs.

Hi there, I've received a question from an end user, which I presume the answer is "No", but would like to ask the community first. Scenario: The user wants to create a series of jobs that all need to start at the same time. Example: there are 10 different executable applications which have varying CPU and RAM constraints, all of which need to communicate via TCP/IP. Of course the user could design some type of idle/statusing mechanism to wait until all jobs are randomly started, then begin execution, but this feels like a waste of resources. The complete execution of these 10 applications would be considered a single simulation. The goal would be to distribute these 10 applications across the cluster and not necessarily require them all to execute on a single node. Is there a good architecture for this using SLURM? If so, please kindly point me in the right direction. -- Thanks, Daniel Healy
