[Swift-devel] RAM needs for running a swift workflow

[Mike Wilde]

Does anyone have any data on how much memory is used for simple swift 
workflows, and how that scales up?

I ask because if we have numerous students in a workshop running swift on the 
same submit host, we need to know how many it can handle before it consumes 
all RAM and starts paging/swapping.

A good thing to measure in the future for our application workflows (albeit 
not the most critical for most applications).

Alternatively - with the current command set, is there a practical way to have 
many users share the same JVM to run small independent workflows?  (I assume 
not, and that this might be a feature to consider in the distant future. Would 
there be much savings for sharing a JVM, or is more of the memory overhead 
per-workflow than per-JVM?)
