[Swift-user] max number of jobs?

[Ioan Raicu]

I can't help with the Swift or coaster settings, but don't forget that 
Falkon is also installed on Ranger, and you can use it the same way that 
you use it on intrepid. I have yet to do extremely large runs on ranger 
to see how well things scale, but you might want to give Falkon a try as 
well.

Also, I recall something about the development queue being limited to 16 
or 32 nodes. The normal queue, which allows larger allocations, usually 
also has higher wait times. Coaster might be configured to use the 
faster development queue, which has a limited number of nodes you can 
use. You might want to look into changing the queue Swift/Coaster 
submits the jobs to. Perhaps Mihael or others can offer details on how 
to change the queue Swift will submit to.
